 ### Language
 
+The set of operations allowed in constant expressions has been expanded as
+described in
+the [constant update proposal](https://github.com/dart-lang/language/issues/61).
+The control flow and spread collection features shipped in Dart 2.3 are now also
+supported in constants
+as
+[described in the specification here](https://github.com/dart-lang/language/blob/master/accepted/2.3/unified-collections/feature-specification.md#constant-semantics).
+
+Specifically, it is now valid to use the following operations in constant
+expressions under the appropriate conditions:
+  - Casts (`e as T`) and type tests (`e is T`).
+  - Comparisons to `null`, even for types which override the `==` operator.
+  - The `&`, `|`, and `^` binary operators on booleans.
+  - The spread operators (`...` and `...?`).
+  - An `if` element in a collection literal.
+
+```dart
+// Example: these are now valid constants.
+const i = 3;
+const list = [i as int];
+const set = {if (list is List<int>) ...list};
+const map = {if (i is int) i : "int"};
+```
+
+In addition, the semantics of constant evaluation has been changed as follows:
+  - The `&&` operator only evaluates its second operand if the first evaluates
+  to true.
+  - The `||` operator only evaluates its second operand if the first evaluates
+  to false.
+  - The `??` operator only evaluates its second operand if the first evaluates
+  to null.
+  - The conditional operator (`e ? e1 : e2`) only evaluates one of the two
+    branches, depending on the value of the first operand.
+
+```dart
+// Example: x is now a valid constant definition.
+const String s = null;
+const int x = (s == null) ? 0 : s.length;
+```
+

+The Dart-to-JavaScript compilers — dartdevc and dart2js — recognize these
+annotations, using them to connect your Dart code with JavaScript.
+
+**Important:** This library supercedes `dart:js`, so don't import `dart:js`.
+Instead, import `package:js/js.dart`.
+
+A second library in this package, `js_util`, provides low-level utilities
+that you can use when it isn't possible to wrap JavaScript with a static, annotated API.
+
+
+## Example
 
 See the [Chart.js Dart API](https://github.com/google/chartjs.dart/) for an
 end-to-end example.

+# AOT code size analysis
+
+The Dart VM's AOT compiler has support for emitting binary size information
+for all the code that gets generated. This information can then be visualized.
+
+## Telling the AOT compiler to generate binary size information
+
+Our AOT compiler accepts an extra `--print-instructions-sizes-to=sizes.json`
+flag. If supplied the AOT compiler will emit binary size information for all
+generated functions to `sizes.json`.
+
+This flag can be passed to `gen_snapshot` directly, or to the various wrapper
+scripts (e.g. `pkg/vm/tool/precompiler2`):
+
+```
+% tools/build.py -mrelease -ax64 runtime_kernel dart_precompiled_runtime
+% pkg/vm/tool/precompiler2 --print-instructions-sizes-to=hello_sizes.json hello.dart hello.dart.aot
+```
+
+## Visualizing the information from the binary size json file
+
+To visualize the information emitted by the AOT compiler one can use our binary
+size analysis tool:
+
+```
+% dart pkg/vm/bin/run_binary_size_analysis.dart hello_sizes.json hello_sizes
+Generated file:///.../sdk/hello_sizes/index.html
+% chrome hello_sizes/index.html
+```

+## Object IDs
+
+An object id is a 1-origin index into SnapshotGraph.objects.

-# Dart VM Service Protocol 3.26-dev
-
-> Please post feedback to the [observatory-discuss group][discuss-list]
-
-This document describes of _version 3.26-dev_ of the Dart VM Service Protocol. This
-protocol is used to communicate with a running Dart Virtual Machine.
-
-To use the Service Protocol, start the VM with the *--observe* flag.
-The VM will start a webserver which services protocol requests via WebSocket.
-It is possible to make HTTP (non-WebSocket) requests,
-but this does not allow access to VM _events_ and is not documented

-## RPCs, Requests, and Responses
-
-An RPC request is a JSON object sent to the server. Here is an
-example [getVersion](#getversion) request:
-
-```
-{
-  "jsonrpc": "2.0",
-  "method": "getVersion",
-  "params": {},
-  "id": "1"
-}
-```
-
-The _id_ property must be a string, number, or `null`. The Service Protocol
-optionally accepts requests without the _jsonprc_ property.
-
-An RPC response is a JSON object (http://json.org/). The response always specifies an
-_id_ property to pair it with the corresponding request. If the RPC
-was successful, the _result_ property provides the result.
-
-Here is an example response for our [getVersion](#getversion) request above:
-
-```
-{
-  "jsonrpc": "2.0",
-  "result": {
-    "type": "Version",
-    "major": 3,
-    "minor": 5
-  }
-  "id": "1"
-}
-```
-
-Parameters for RPC requests are always provided as _named_ parameters.
-The JSON-RPC spec provides for _positional_ parameters as well, but they
-are not supported by the Dart VM.
-
-By convention, every response returned by the Service Protocol is a subtype
-of [Response](#response) and provides a _type_ parameter which can be used
-to distinguish the exact return type. In the example above, the
-[Version](#version) type is returned.
-
-Here is an example [streamListen](#streamlisten) request which provides
-a parameter:
-
-```
-{
-  "jsonrpc": "2.0",
-  "method": "streamListen",
-  "params": {
-    "streamId": "GC"
-  },
-  "id": "2"
-}
-```
-
-<a name="rpc-error"></a>
-When an RPC encounters an error, it is provided in the _error_
-property of the response object. JSON-RPC errors always provide
-_code_, _message_, and _data_ properties.
-
-Here is an example error response for our [streamListen](#streamlisten)
-request above. This error would be generated if we were attempting to
-subscribe to the _GC_ stream multiple times from the same client.
-
-```
-{
-  "jsonrpc": "2.0",
-  "error": {
-    "code": 103,
-    "message": "Stream already subscribed",
-    "data": {
-      "details": "The stream 'GC' is already subscribed"
-    }
-  }
-  "id": "2"
-}
-```
-
-In addition to the [error codes](http://www.jsonrpc.org/specification#error_object) specified in the JSON-RPC spec, we use the following application specific error codes:
-
-code | message | meaning
----- | ------- | -------
-100 | Feature is disabled | The operation is unable to complete because a feature is disabled
-101 | VM must be paused | This operation is only valid when the VM is paused
-102 | Cannot add breakpoint | The VM is unable to add a breakpoint at the specified line or function
-103 | Stream already subscribed | The client is already subscribed to the specified _streamId_
-104 | Stream not subscribed | The client is not subscribed to the specified _streamId_
-105 | Isolate must be runnable | This operation cannot happen until the isolate is runnable
-106 | Isolate must be paused | This operation is only valid when the isolate is paused
-107 | Cannot resume execution | The isolate could not be resumed
-108 | Isolate is reloading | The isolate is currently processing another reload request
-109 | Isolate cannot be reloaded | The isolate has an unhandled exception and can no longer be reloaded
-110 | Isolate must have reloaded | Failed to find differences in last hot reload request
-111 | Service already registered | Service with such name has already been registered by this client
-112 | Service disappeared | Failed to fulfill service request, likely service handler is no longer available
-113 | Expression compilation error | Request to compile expression failed
-114 | Invalid timeline request | The timeline related request could not be completed due to the current configuration
-
-## Events
-
-By using the [streamListen](#streamlisten) and [streamCancel](#streamcancel) RPCs, a client may
-request to be notified when an _event_ is posted to a specific
-_stream_ in the VM. Every stream has an associated _stream id_ which
-is used to name that stream.
-
-Each stream provides access to certain kinds of events. For example the _Isolate_ stream provides
-access to events pertaining to isolate births, deaths, and name changes. See [streamListen](#streamlisten)
-for a list of the well-known stream ids and their associated events.
-
-Stream events arrive asynchronously over the WebSocket. They're structured as
-JSON-RPC 2.0 requests with no _id_ property. The _method_ property will be
-_streamNotify_, and the _params_ will have _streamId_ and _event_ properties:
-
-```json
-{
-  "json-rpc": "2.0",
-  "method": "streamNotify",
-  "params": {
-    "streamId": "Isolate",
-    "event": {
-      "type": "Event",
-      "kind": "IsolateExit",
-      "isolate": {
-        "type": "@Isolate",
-        "id": "isolates/33",
-        "number": "51048743613",
-        "name": "worker-isolate"
-      }
-    }
-  }
-}
-```
-
-It is considered a _backwards compatible_ change to add a new type of event to an existing stream.
-Clients should be written to handle this gracefully.
-
-
-
-## Types
-
-By convention, every result and event provided by the Service Protocol
-is a subtype of [Response](#response) and has the _type_ property.
-This allows the client to distinguish different kinds of responses. For example,
-information about a Dart function is returned using the [Function](#function) type.
-
-If the type of a response begins with the _@_ character, then that
-response is a _reference_. If the type name of a response does not
-begin with the _@_ character, it is an _object_. A reference is
-intended to be a subset of an object which provides enough information
-to generate a reasonable looking reference to the object.
-
-For example, an [@Isolate](#isolate) reference has the _type_, _id_, _name_ and
-_number_ properties:
-
-```
-  "result": {
-    "type": "@Isolate",
-    "id": "isolates/33",
-    "number": "51048743613"
-    "name": "worker-isolate"
-  }
-```
-
-But an [Isolate](#isolate) object has more information:
-
-```
-  "result": {
-    "type": "Isolate",
-    "id": "isolates/33",
-    "number": "51048743613"
-    "name": "worker-isolate"
-    "rootLib": { ... }
-    "entry": ...
-    "heaps": ...
-     ...
-  }
-```
-
-## IDs and Names
-
-Many responses returned by the Service Protocol have an _id_ property.
-This is an identifier used to request an object from an isolate using
-the [getObject](#getobject) RPC. If two responses have the same _id_ then they
-refer to the same object. The converse is not true: the same object
-may sometimes be returned with two different values for _id_.
-
-The _id_ property should be treated as an opaque string by the client:
-it is not meant to be parsed.
-
-An id can be either _temporary_ or _fixed_:
-
-* A _temporary_ id can expire over time. The VM allocates certain ids
-  in a ring which evicts old ids over time.
-
-* A _fixed_ id will never expire, but the object it refers to may
-  be collected. The VM uses fixed ids for objects like scripts,
-  libraries, and classes.
-
-If an id is fixed, the _fixedId_ property will be true. If an id is temporary
-the _fixedId_ property will be omitted.
-
-Sometimes a temporary id may expire. In this case, some RPCs may return
-an _Expired_ [Sentinel](#sentinel) to indicate this.
-
-The object referred to by an id may be collected by the VM's garbage
-collector. In this case, some RPCs may return a _Collected_ [Sentinel](#sentinel)
-to indicate this.
-
-Many objects also have a _name_ property. This is provided so that
-objects can be displayed in a way that a Dart language programmer
-would find familiar. Names are not unique.
-
-## Versioning
-
-The [getVersion](#getversion) RPC can be used to find the version of the protocol
-returned by a VM. The _Version_ response has a major and a minor
-version number:
-
-```
-  "result": {
-    "type": "Version",
-    "major": 3,
-    "minor": 5
-  }
-```
-
-The major version number is incremented when the protocol is changed
-in a potentially _incompatible_ way. An example of an incompatible
-change is removing a non-optional property from a result.
-
-The minor version number is incremented when the protocol is changed
-in a _backwards compatible_ way. An example of a backwards compatible
-change is adding a property to a result.
-
-Certain changes that would normally not be backwards compatible are
-considered backwards compatible for the purposes of versioning.
-Specifically, additions can be made to the [EventKind](#eventkind) and
-[InstanceKind](#instancekind) enumerated types and the client must
-handle this gracefully. See the notes on these enumerated types for more
-information.
-
-## Private RPCs, Types, and Properties
-
-Any RPC, type, or property which begins with an underscore is said to
-be _private_. These RPCs, types, and fields can be changed at any
-time without changing major or minor version numbers.
-
-The intention is that the Service Protocol will evolve by adding
-private RPCs which may, over time, migrate to the public api as they
-become stable. Some private types and properties expose VM specific
-implementation state and will never be appropriate to add to
-the public api.
-
-## Public RPCs
-
-The following is a list of all public RPCs supported by the Service Protocol.
-
-An RPC is described using the following format:
-
-```
-ReturnType methodName(parameterType1 parameterName1,
-                      parameterType2 parameterName2,
-                      ...)
-```
-
-If an RPC says it returns type _T_ it may actually return _T_ or any
-[subtype](#public-types) of _T_. For example, an
-RPC which is declared to return [@Object](#object) may actually
-return [@Instance](#instance).
-
-If an RPC can return one or more independent types, this is indicated
-with the vertical bar:
-
-```
-ReturnType1|ReturnType2
-```
-
-Any RPC may return an _error_ response as [described above](#rpc-error).
-
-Some parameters are optional. This is indicated by the text
-_[optional]_ following the parameter name:
-
-```
-ReturnType methodName(parameterType parameterName [optional])
-```
-
-A description of the return types and parameter types is provided
-in the section on [public types](#public-types).
-
-### addBreakpoint
-
-```
-Breakpoint addBreakpoint(string isolateId,
-                         string scriptId,
-                         int line,
-                         int column [optional])
-```
-
-The _addBreakpoint_ RPC is used to add a breakpoint at a specific line
-of some script.
-
-The _scriptId_ parameter is used to specify the target script.
-
-The _line_ parameter is used to specify the target line for the
-breakpoint. If there are multiple possible breakpoints on the target
-line, then the VM will place the breakpoint at the location which
-would execute soonest. If it is not possible to set a breakpoint at
-the target line, the breakpoint will be added at the next possible
-breakpoint location within the same function.
-
-The _column_ parameter may be optionally specified.  This is useful
-for targeting a specific breakpoint on a line with multiple possible
-breakpoints.
-
-If no breakpoint is possible at that line, the _102_ (Cannot add
-breakpoint) error code is returned.
-
-Note that breakpoints are added and removed on a per-isolate basis.
-
-See [Breakpoint](#breakpoint).
-
-### addBreakpointWithScriptUri
-
-```
-Breakpoint addBreakpointWithScriptUri(string isolateId,
-                                      string scriptUri,
-                                      int line,
-                                      int column [optional])
-```
-
-The _addBreakpoint_ RPC is used to add a breakpoint at a specific line
-of some script.  This RPC is useful when a script has not yet been
-assigned an id, for example, if a script is in a deferred library
-which has not yet been loaded.
-
-The _scriptUri_ parameter is used to specify the target script.
-
-The _line_ parameter is used to specify the target line for the
-breakpoint. If there are multiple possible breakpoints on the target
-line, then the VM will place the breakpoint at the location which
-would execute soonest. If it is not possible to set a breakpoint at
-the target line, the breakpoint will be added at the next possible
-breakpoint location within the same function.
-
-The _column_ parameter may be optionally specified.  This is useful
-for targeting a specific breakpoint on a line with multiple possible
-breakpoints.
-
-If no breakpoint is possible at that line, the _102_ (Cannot add
-breakpoint) error code is returned.
-
-Note that breakpoints are added and removed on a per-isolate basis.
-
-See [Breakpoint](#breakpoint).
-
-### addBreakpointAtEntry
-
-```
-Breakpoint addBreakpointAtEntry(string isolateId,
-                                string functionId)
-```
-The _addBreakpointAtEntry_ RPC is used to add a breakpoint at the
-entrypoint of some function.
-
-If no breakpoint is possible at the function entry, the _102_ (Cannot add
-breakpoint) error code is returned.
-
-See [Breakpoint](#breakpoint).
-
-Note that breakpoints are added and removed on a per-isolate basis.
-
-
-### clearVMTimeline
-
-```
-Success clearVMTimeline()
-```
-
-Clears all VM timeline events.
-
-See [Success](#success).
-
-### invoke
-
-```
-@Instance|@Error|Sentinel invoke(string isolateId,
-                                 string targetId,
-                                 string selector,
-                                 string[] argumentIds,
-                                 bool disableBreakpoints [optional])
-```
-
-The _invoke_ RPC is used to perform regular method invocation on some receiver,
-as if by dart:mirror's ObjectMirror.invoke. Note this does not provide a way to
-perform getter, setter or constructor invocation.
-
-_targetId_ may refer to a [Library](#library), [Class](#class), or
-[Instance](#instance).
-
-Each elements of _argumentId_ may refer to an [Instance](#instance).
-
-If _disableBreakpoints_ is provided and set to true, any breakpoints hit as a
-result of this invocation are ignored, including pauses resulting from a call
-to `debugger()` from `dart:developer`. Defaults to false if not provided.
-
-If _targetId_ or any element of _argumentIds_ is a temporary id which has
-expired, then the _Expired_ [Sentinel](#sentinel) is returned.
-
-If _targetId_ or any element of _argumentIds_ refers to an object which has been
-collected by the VM's garbage collector, then the _Collected_
-[Sentinel](#sentinel) is returned.
-
-If invocation triggers a failed compilation then [rpc error](#rpc-error) 113
-"Expression compilation error" is returned.
-
-If an runtime error occurs while evaluating the invocation, an [@Error](#error)
-reference will be returned.
-
-If the invocation is evaluated successfully, an [@Instance](#instance)
-reference will be returned.
-
-### evaluate
-
-```
-@Instance|@Error|Sentinel evaluate(string isolateId,
-                                   string targetId,
-                                   string expression,
-                                   map<string,string> scope [optional],
-                                   bool disableBreakpoints [optional])
-```
-
-The _evaluate_ RPC is used to evaluate an expression in the context of
-some target.
-
-_targetId_ may refer to a [Library](#library), [Class](#class), or
-[Instance](#instance).
-
-If _targetId_ is a temporary id which has expired, then the _Expired_
-[Sentinel](#sentinel) is returned.
-
-If _targetId_ refers to an object which has been collected by the VM's
-garbage collector, then the _Collected_ [Sentinel](#sentinel) is
-returned.
-
-If _scope_ is provided, it should be a map from identifiers to object ids.
-These bindings will be added to the scope in which the expression is evaluated,
-which is a child scope of the class or library for instance/class or library
-targets respectively. This means bindings provided in _scope_ may shadow
-instance members, class members and top-level members.
-
-If _disableBreakpoints_ is provided and set to true, any breakpoints hit as a
-result of this evaluation are ignored. Defaults to false if not provided.
-
-If the expression fails to parse and compile, then [rpc error](#rpc-error) 113
-"Expression compilation error" is returned.
-
-If an error occurs while evaluating the expression, an [@Error](#error)
-reference will be returned.
-
-If the expression is evaluated successfully, an [@Instance](#instance)
-reference will be returned.
-
-### evaluateInFrame
-
-```
-@Instance|@Error|Sentinel evaluateInFrame(string isolateId,
-                                          int frameIndex,
-                                          string expression,
-                                          map<string,string> scope [optional],
-                                          bool disableBreakpoints [optional])
-```
-
-The _evaluateInFrame_ RPC is used to evaluate an expression in the
-context of a particular stack frame. _frameIndex_ is the index of the
-desired [Frame](#frame), with an index of _0_ indicating the top (most
-recent) frame.
-
-If _scope_ is provided, it should be a map from identifiers to object ids.
-These bindings will be added to the scope in which the expression is evaluated,
-which is a child scope of the frame's current scope. This means bindings
-provided in _scope_ may shadow instance members, class members, top-level
-members, parameters and locals.
-
-If _disableBreakpoints_ is provided and set to true, any breakpoints hit as a
-result of this evaluation are ignored. Defaults to false if not provided.
-
-If the expression fails to parse and compile, then [rpc error](#rpc-error) 113
-"Expression compilation error" is returned.
-
-If an error occurs while evaluating the expression, an [@Error](#error)
-reference will be returned.
-
-If the expression is evaluated successfully, an [@Instance](#instance)
-reference will be returned.
-
-### getAllocationProfile
-
-```
-AllocationProfile getAllocationProfile(string isolateId,
-                                       bool reset [optional],
-                                       bool gc [optional])
-```
-
-The _getAllocationProfile_ RPC is used to retrieve allocation information for a
-given isolate.
-
-If _reset_ is provided and is set to true, the allocation accumulators will be reset
-before collecting allocation information.
-
-If _gc_ is provided and is set to true, a garbage collection will be attempted
-before collecting allocation information. There is no guarantee that a garbage
-collection will be actually be performed.
-
-### getFlagList
-
-```
-FlagList getFlagList()
-```
-
-The _getFlagList_ RPC returns a list of all command line flags in the
-VM along with their current values.
-
-See [FlagList](#flaglist).
-
-### getInboundReferences
-
-```
-InboundReferences|Sentinel getInboundReferences(string isolateId,
-                                                string targetId,
-                                                int limit)
-```
-
-Returns a set of inbound references to the object specified by _targetId_. Up to
-_limit_ references will be returned.
-
-The order of the references is undefined (i.e., not related to allocation order)
-and unstable (i.e., multiple invocations of this method against the same object
-can give different answers even if no Dart code has executed between the invocations).
-
-The references may include multiple `objectId`s that designate the same object.
-
-The references may include objects that are unreachable but have not yet been garbage collected.
-
-If _targetId_ is a temporary id which has expired, then the _Expired_
-[Sentinel](#sentinel) is returned.
-
-If _targetId_ refers to an object which has been collected by the VM's
-garbage collector, then the _Collected_ [Sentinel](#sentinel) is
-returned.
-
-See [InboundReferences](#inboundreferences).
-
-### getInstances
-
-```
-InstanceSet getInstances(string isolateId,
-                         string objectId,
-                         int limit)
-```
-
-The _getInstances_ RPC is used to retrieve a set of instances which are of a
-specific class. This does not include instances of subclasses of the given
-class.
-
-The order of the instances is undefined (i.e., not related to allocation order)
-and unstable (i.e., multiple invocations of this method against the same class
-can give different answers even if no Dart code has executed between the
-invocations).
-
-The set of instances may include objects that are unreachable but have not yet
-been garbage collected.
-
-_objectId_ is the ID of the `Class` to retrieve instances for. _objectId_ must
-be the ID of a `Class`, otherwise an error is returned.
-
-_limit_ is the maximum number of instances to be returned.
-
-See [InstanceSet](#instanceset).
-
-### getIsolate
-
-```
-Isolate|Sentinel getIsolate(string isolateId)
-```
-
-The _getIsolate_ RPC is used to lookup an _Isolate_ object by its _id_.
-
-If _isolateId_ refers to an isolate which has exited, then the
-_Collected_ [Sentinel](#sentinel) is returned.
-
-See [Isolate](#isolate).
-
-### getMemoryUsage
-
-```
-MemoryUsage|Sentinel getMemoryUsage(string isolateId)
-```
-
-The _getMemoryUsage_ RPC is used to lookup an isolate's memory usage
-statistics by its _id_.

-                          int count [optional])
-```
-
-The _getObject_ RPC is used to lookup an _object_ from some isolate by
-its _id_.
-
-If _objectId_ is a temporary id which has expired, then the _Expired_
-[Sentinel](#sentinel) is returned.
-
-If _objectId_ refers to a heap object which has been collected by the VM's
-garbage collector, then the _Collected_ [Sentinel](#sentinel) is
-returned.
-
-If _objectId_ refers to a non-heap object which has been deleted, then
-the _Collected_ [Sentinel](#sentinel) is returned.
-
-If the object handle has not expired and the object has not been
-collected, then an [Object](#object) will be returned.
-
-The _offset_ and _count_ parameters are used to request subranges of
-Instance objects with the kinds: String, List, Map, Uint8ClampedList,
-Uint8List, Uint16List, Uint32List, Uint64List, Int8List, Int16List,
-Int32List, Int64List, Flooat32List, Float64List, Inst32x3List,

-                               int limit)
-```
-
-The _getRetainingPath_ RPC is used to lookup a path from an object specified by
-_targetId_ to a GC root (i.e., the object which is preventing this object from
-being garbage collected).
-
-If _targetId_ refers to a heap object which has been collected by the VM's
-garbage collector, then the _Collected_ [Sentinel](#sentinel) is returned.
-
-If _targetId_ refers to a non-heap object which has been deleted, then the
-_Collected_ [Sentinel](#sentinel) is returned.
-
-If the object handle has not expired and the object has not been collected, then
-an [RetainingPath](#retainingpath) will be returned.
-
-The _limit_ parameter specifies the maximum path length to be reported as part
-of the retaining path. If a path is longer than _limit_, it will be truncated at
-the root end of the path.
-
-See [RetainingPath](#retainingpath).
-
-### getStack
-
-```
-Stack getStack(string isolateId)
-```

-                             bool forceCompile [optional])
-```
-
-The _getSourceReport_ RPC is used to generate a set of reports tied to
-source locations in an isolate.
-
-The _reports_ parameter is used to specify which reports should be
-generated.  The _reports_ parameter is a list, which allows multiple
-reports to be generated simultaneously from a consistent isolate
-state.  The _reports_ parameter is allowed to be empty (this might be
-used to force compilation of a particular subrange of some script).
-
-The available report kinds are:
-
-report kind | meaning
------------ | -------
-Coverage | Provide code coverage information
-PossibleBreakpoints | Provide a list of token positions which correspond to possible breakpoints.
-
-The _scriptId_ parameter is used to restrict the report to a
-particular script.  When analyzing a particular script, either or both
-of the _tokenPos_ and _endTokenPos_ parameters may be provided to
-restrict the analysis to a subrange of a script (for example, these
-can be used to restrict the report to the range of a particular class
-or function).
-
-If the _scriptId_ parameter is not provided then the reports are
-generated for all loaded scripts and the _tokenPos_ and _endTokenPos_
-parameters are disallowed.
-
-The _forceCompilation_ parameter can be used to force compilation of
-all functions in the range of the report.  Forcing compilation can
-cause a compilation error, which could terminate the running Dart
-program.  If this parameter is not provided, it is considered to have
-the value _false_.
-
-See [SourceReport](#sourcereport).
-
-### getVersion
-
-```
-Version getVersion()
-```
-

-### getVMTimeline
-
-```
-Timeline getVMTimeline(int timeOriginMicros [optional],
-                       int timeExtentMicros [optional])
-```
-
-The _getVMTimeline_ RPC is used to retrieve an object which contains VM timeline
-events.
-
-The _timeOriginMicros_ parameter is the beginning of the time range used to filter
-timeline events. It uses the same monotonic clock as dart:developer's `Timeline.now`
-and the VM embedding API's `Dart_TimelineGetMicros`. See [getVMTimelineMicros](#getvmtimelinemicros)
-for access to this clock through the service protocol.
-
-The _timeExtentMicros_ parameter specifies how large the time range used to filter
-timeline events should be.
-
-For example, given _timeOriginMicros_ and _timeExtentMicros_, only timeline events
-from the following time range will be returned: `(timeOriginMicros, timeOriginMicros + timeExtentMicros)`.
-
-If _getVMTimeline_ is invoked while the current recorder is one of Fuchsia or
-Systrace, the _114_ error code, invalid timeline request, will be returned as
-timeline events are handled by the OS in these modes.
-
-### getVMTimelineFlags
-
-```
-TimelineFlags getVMTimelineFlags()
-```
-
-The _getVMTimelineFlags_ RPC returns information about the current VM timeline configuration.

-
-### kill
-
-```
-Success kill(string isolateId)
-```

-```
-
-The _reloadSources_ RPC is used to perform a hot reload of an Isolate's sources.
-
-if the _force_ parameter is provided, it indicates that all of the Isolate's
-sources should be reloaded regardless of modification time.
-
-if the _pause_ parameter is provided, the isolate will pause immediately
-after the reload.
-
-if the _rootLibUri_ parameter is provided, it indicates the new uri to the
-Isolate's root library.
-
-if the _packagesUri_ parameter is provided, it indicates the new uri to the

-               StepOption step [optional],
-               int frameIndex [optional])
-```
-
-The _resume_ RPC is used to resume execution of a paused isolate.
-
-If the _step_ parameter is not provided, the program will resume
-regular execution.
-
-If the _step_ parameter is provided, it indicates what form of
-single-stepping to use.
-
-step | meaning
----- | -------
-Into | Single step, entering function calls
-Over | Single step, skipping over function calls
-Out | Single step until the current function exits
-Rewind | Immediately exit the top frame(s) without executing any code. Isolate will be paused at the call of the last exited function.
-
-The _frameIndex_ parameter is only used when the _step_ parameter is Rewind. It
-specifies the stack frame to rewind to. Stack frame 0 is the currently executing
-function, so _frameIndex_ must be at least 1.
-
-If the _frameIndex_ parameter is not provided, it defaults to 1.
-
-See [Success](#success), [StepOption](#StepOption).
-
-### setExceptionPauseMode
-
-```
-Success setExceptionPauseMode(string isolateId,
-                              ExceptionPauseMode mode)
-```

-All  | Pause isolate on all thrown exceptions
-
-### setFlag
-
-```
-Success setFlag(string name,
-                string value)
-```
-
-The _setFlag_ RPC is used to set a VM flag at runtime. Returns an error if the

-of the wrong type for the flag.
-
-The following flags may be set at runtime:
-
- * pause_isolates_on_start
- * pause_isolates_on_exit
- * pause_isolates_on_unhandled_exceptions
- * profile_period
-
-Note: `profile_period` can be set to a minimum value of 50. Attempting to set

-
-See [Success](#success).
-
-### setName
-
-```
-Success setName(string isolateId,
-                string name)

-
-See [Success](#success).
-
-### streamCancel
-
-```
-Success streamCancel(string streamId)
-```
-
-The _streamCancel_ RPC cancels a stream subscription in the VM.
-
-If the client is not subscribed to the stream, the _104_ (Stream not
-subscribed) error code is returned.
-
-See [Success](#success).
-
-### streamListen
-
-```
-Success streamListen(string streamId)
-```
-
-The _streamListen_ RPC subscribes to a stream in the VM. Once
-subscribed, the client will begin receiving events from the stream.
-
-If the client is already subscribed to the stream, the _103_ (Stream already
-subscribed) error code is returned.
-
-The _streamId_ parameter may have the following published values:
-
-streamId | event types provided
--------- | -----------
-VM | VMUpdate, VMFlagUpdate
-Isolate | IsolateStart, IsolateRunnable, IsolateExit, IsolateUpdate, IsolateReload, ServiceExtensionAdded

-streams.  These streams allow the client to subscribe to writes to
-stdout and stderr.
-
-streamId | event types provided
--------- | -----------
-Stdout | WriteEvent
-Stderr | WriteEvent
-
-It is considered a _backwards compatible_ change to add a new type of event to an existing stream.
-Clients should be written to handle this gracefully, perhaps by warning and ignoring.
-
-See [Success](#success).
-
-## Public Types
-
-The following is a list of all public types produced by the Service Protocol.
-
-We define a small set of primitive types, based on JSON equivalents.
-
-type | meaning
----- | -------
-string | JSON string values
-bool | JSON _true_, _false_
-int | JSON numbers without fractions or exponents
-float | any JSON number
-
-Note that the Service Protocol does not use JSON _null_.
-
-We describe the format of our JSON objects with the following class format:
-
-```
-class T {
-  string name;
-  int count;
-  ...
-}
-```
-
-This describes a JSON object type _T_ with some set of expected properties.
-
-Types are organized into an inheritance hierarchy. If type _T_
-extends type _S_...
-
-```
-class S {
-  string a;
-}
-
-class T extends S {
-  string b;
-}
-```
-
-...then that means that all properties of _S_ are also present in type
-_T_. In the example above, type _T_ would have the expected
-properties _a_ and _b_.
-
-If a property has an _Array_ type, it is written with brackets:
-
-```
-  PropertyType[] arrayProperty;
-```
-
-If a property is optional, it is suffixed with the text _[optional]_:
-
-```
-  PropertyType optionalProperty [optional];
-```
-
-If a property can have multiple independent types, we denote this with
-a vertical bar:
-
-```
-  PropertyType1|PropertyType2 complexProperty;
-```
-
-We also allow parenthesis on type expressions.  This is useful when a property
-is an _Array_ of multiple independent types:
-
-```
-  (PropertyType1|PropertyType2)[]
-```
-
-When a string is only permitted to take one of a certain set of values,
-we indicate this by the use of the _enum_ format:
-
-```
-enum PermittedValues {
-  Value1,
-  Value2
-}
-```
-
-This means that _PermittedValues_ is a _string_ with two potential values,
-_Value1_ and _Value2_.
-
-### AllocationProfile
-
-```
-class AllocationProfile extends Response {
-  // Allocation information for all class types.
-  ClassHeapStats[] members;
-
-  // Information about memory usage for the isolate.
-  MemoryUsage memoryUsage;
-
-  // The timestamp of the last accumulator reset.
-  //
-  // If the accumulators have not been reset, this field is not present.
-  int dateLastAccumulatorReset [optional];
-
-  // The timestamp of the last manually triggered GC.
-  //
-  // If a GC has not been triggered manually, this field is not present.
-  int dateLastServiceGC [optional];
-}
-```
-
-### BoundField
-
-```
-class BoundField {
-  @Field decl;
-  @Instance|Sentinel value;
-}
-```
-
-A _BoundField_ represents a field bound to a particular value in an
-_Instance_.
-
-If the field is uninitialized, the _value_ will be the
-_NotInitialized_ [Sentinel](#sentinel).
-
-If the field is being initialized, the _value_ will be the
-_BeingInitialized_ [Sentinel](#sentinel).
-
-### BoundVariable
-
-```
-class BoundVariable extends Response {
-  string name;
-  @Instance|@TypeArguments|Sentinel value;
-
-  // The token position where this variable was declared.
-  int declarationTokenPos;
-
-  // The first token position where this variable is visible to the scope.
-  int scopeStartTokenPos;
-
-  // The last token position where this variable is visible to the scope.
-  int scopeEndTokenPos;
-}
-```
-
-A _BoundVariable_ represents a local variable bound to a particular value
-in a _Frame_.
-
-If the variable is uninitialized, the _value_ will be the
-_NotInitialized_ [Sentinel](#sentinel).
-
-If the variable is being initialized, the _value_ will be the
-_BeingInitialized_ [Sentinel](#sentinel).
-
-If the variable has been optimized out by the compiler, the _value_
-will be the _OptimizedOut_ [Sentinel](#sentinel).
-
-### Breakpoint
-
-```
-class Breakpoint extends Object {
-  // A number identifying this breakpoint to the user.
-  int breakpointNumber;
-
-  // Has this breakpoint been assigned to a specific program location?
-  bool resolved;
-
-  // Is this a breakpoint that was added synthetically as part of a step
-  // OverAsyncSuspension resume command?
-  bool isSyntheticAsyncContinuation [optional];
-
-  // SourceLocation when breakpoint is resolved, UnresolvedSourceLocation
-  // when a breakpoint is not resolved.
-  SourceLocation|UnresolvedSourceLocation location;
-}
-```
-
-A _Breakpoint_ describes a debugger breakpoint.
-
-A breakpoint is _resolved_ when it has been assigned to a specific
-program location.  A breakpoint my remain unresolved when it is in
-code which has not yet been compiled or in a library which has not
-been loaded (i.e. a deferred library).

-}
-```
-
-A _Sentinel_ is used to indicate that the normal response is not available.
-
-We use a _Sentinel_ instead of an [error](#errors) for these cases because
-they do not represent a problematic condition. They are normal.
-
-### SentinelKind
-
-```
-enum SentinelKind {
-  // Indicates that the object referred to has been collected by the GC.
-  Collected,
-
-  // Indicates that an object id has expired.

-
-  // Reserved for future use.
-  Free,
-}
-```
-
-A _SentinelKind_ is used to distinguish different kinds of _Sentinel_ objects.
-
-Adding new values to _SentinelKind_ is considered a backwards
-compatible change. Clients must handle this gracefully.

-
-A _Script_ provides information about a Dart language script.
-
-The _tokenPosTable_ is an array of int arrays. Each subarray
-consists of a line number followed by _(tokenPos, columnNumber)_ pairs:
-
-> [lineNumber, (tokenPos, columnNumber)*]
-
-The _tokenPos_ is an arbitrary integer value that is used to represent
-a location in the source code.  A _tokenPos_ value is not meaningful
-in itself and code should not rely on the exact values returned.
-
-For example, a _tokenPosTable_ with the value...
-
-> [[1, 100, 5, 101, 8],[2, 102, 7]]
-
-...encodes the mapping:
-
-tokenPos | line | column

-  SourceReportRange[] ranges;
-
-  // A list of scripts, referenced by index in the report's ranges.
-  ScriptRef[] scripts;
-}
-```
-
-The _SourceReport_ class represents a set of reports tied to source
-locations in an isolate.
-
-### SourceReportCoverage
-
-```
-class SourceReportCoverage {
-  // A list of token positions in a SourceReportRange which have been
-  // executed.  The list is sorted.
-  int[] hits;
-
-  // A list of token positions in a SourceReportRange which have not been
-  // executed.  The list is sorted.
-  int[] misses;
-}
-```
-
-The _SourceReportCoverage_ class represents coverage information for
-one [SourceReportRange](#sourcereportrange).
-
-Note that _SourceReportCoverage_ does not extend [Response](#response)
-and therefore will not contain a _type_ property.

-
-  // The token position at which this range ends.  Inclusive.
-  int endPos;
-
-  // Has this range been compiled by the Dart VM?
-  bool compiled;
-
-  // The error while attempting to compile this range, if this
-  // report was generated with forceCompile=true.
-  @Error error [optional];
-
-  // Code coverage information for this range.  Provided only when the
-  // Coverage report has been requested and the range has been

-}
-```
-
-The _SourceReportRange_ class represents a range of executable code
-(function, method, constructor, etc) in the running program.  It is
-part of a [SourceReport](#sourcereport).
-
-Note that _SourceReportRange_ does not extend [Response](#response)
-and therefore will not contain a _type_ property.

-  string name;
-}
-```
-
-_@TypeArguments_ is a reference to a _TypeArguments_ object.
-
-```
-class TypeArguments extends Object {
-  // A name for this type argument list.
-  string name;
-
-  // A list of types.
-  //
-  // The value will always be one of the kinds:
-  // Type, TypeRef, TypeParameter, BoundedType.
-  @Instance[] types;
-}
-```
-
-A _TypeArguments_ object represents the type argument vector for some
-instantiated generic type.
-
-### UnresolvedSourceLocation
-
-```
-class UnresolvedSourceLocation extends Response {
-  // The script containing the source location if the script has been loaded.

-}
-```
-
-The _UnresolvedSourceLocation_ class is used to refer to an unresolved
-breakpoint location.  As such, it is meant to approximate the final
-location of the breakpoint but it is not exact.
-
-Either the _script_ or the _scriptUri_ field will be present.
-
-Either the _tokenPos_ or the _line_ field will be present.
-

-1.0 | Initial revision
-2.0 | Describe protocol version 2.0.
-3.0 | Describe protocol version 3.0.  Added UnresolvedSourceLocation.  Added Sentinel return to getIsolate.  Add AddedBreakpointWithScriptUri.  Removed Isolate.entry. The type of VM.pid was changed from string to int.  Added VMUpdate events.  Add offset and count parameters to getObject() and offset and count fields to Instance. Added ServiceExtensionAdded event.
-3.1 | Add the getSourceReport RPC.  The getObject RPC now accepts offset and count for string objects.  String objects now contain length, offset, and count properties.
