+## 2.3.0 - 2019-05-08
+
+The focus in this release is on the new "UI-as-code" language features which
+make collections more expressive and declarative.
+
+### Language
+
+Flutter is growing rapidly, which means many Dart users are building UI in code
+out of big deeply-nested expressions. Our goal with 2.3.0 was to [make that kind
+of code easier to write and maintain][ui-as-code]. Collection literals are a
+large component, so we focused on three features to make collections more
+powerful. We'll use list literals in the examples below, but these features also
+work in map and set literals.
+
+[ui-as-code]: https://medium.com/dartlang/making-dart-a-better-language-for-ui-f1ccaf9f546c
+
+#### Spread
+
+Placing `...` before an expression inside a collection literal unpacks the
+result of the expression and inserts its elements directly inside the new
+collection. Where before you had to write something like this:
+
+```dart
+CupertinoPageScaffold(
+ child: ListView(children: [
+ Tab2Header()
+ ]..addAll(buildTab2Conversation())
+ ..add(buildFooter())),
+);
+```
+
+Now you can write this:
+
+```dart
+CupertinoPageScaffold(
+ child: ListView(children: [
+ Tab2Header(),
+ ...buildTab2Conversation(),
+ buildFooter()
+ ]),
+);
+```
+
+If you know the expression might evaluate to null and you want to treat that as
+equivalent to zero elements, you can use the null-aware spread `...?`.
+
+#### Collection if
+
+Sometimes you might want to include one or more elements in a collection only
+under certain conditions. If you're lucky, you can use a `?:` operator to
+selectively swap out a single element, but if you want to exchange more than one
+or omit elements, you are forced to write imperative code like this:
+
+```dart
+Widget build(BuildContext context) {
+ var children = [
+ IconButton(icon: Icon(Icons.menu)),
+ Expanded(child: title)
+ ];
+
+ if (isAndroid) {
+ children.add(IconButton(icon: Icon(Icons.search)));
+ }
+
+ return Row(children: children);
+}
+```
+
+We now allow `if` inside collection literals to conditionally omit or (with
+`else`) swap out an element:
+
+```dart
+Widget build(BuildContext context) {
+ return Row(
+ children: [
+ IconButton(icon: Icon(Icons.menu)),
+ Expanded(child: title),
+ if (isAndroid)
+ IconButton(icon: Icon(Icons.search)),
+ ],
+ );
+}
+```
+
+Unlike the existing `?:` operator, a collection `if` can be composed with
+spreads to conditionally include or omit multiple items:
+
+```dart
+Widget build(BuildContext context) {
+ return Row(
+ children: [
+ IconButton(icon: Icon(Icons.menu)),
+ if (isAndroid) ...[
+ Expanded(child: title),
+ IconButton(icon: Icon(Icons.search)),
+ ]
+ ],
+ );
+}
+```
+
+#### Collection for
+
+In many cases, the higher-order methods on Iterable give you a declarative way
+to modify a collection in the context of a single expression. But some
+operations, especially involving both transforming and filtering, can be
+cumbersome to express in a functional style.
+
+To solve this problem, you can use `for` inside a collection literal. Each
+iteration of the loop produces an element which is then inserted in the
+resulting collection. Consider the following code:
+
+```dart
+var command = [
+ engineDartPath,
+ frontendServer,
+ ...fileSystemRoots.map((root) => "--filesystem-root=$root"),
+ ...entryPoints
+ .where((entryPoint) => fileExists("lib/$entryPoint.json"))
+ .map((entryPoint) => "lib/$entryPoint"),
+ mainPath
+];
+```
+
+With a collection `for`, the code becomes simpler:
+
+```dart
+var command = [
+ engineDartPath,
+ frontendServer,
+ for (var root in fileSystemRoots) "--filesystem-root=$root",
+ for (var entryPoint in entryPoints)
+ if (fileExists("lib/$entryPoint.json")) "lib/$entryPoint",
+ mainPath
+];
+```
+
+As you can see, all three of these features can be freely composed. For full
+details of the changes, see [the official proposal][ui-as-code proposal].
+
+[ui-as-code proposal]: https://github.com/dart-lang/language/blob/master/accepted/future-releases/unified-collections/feature-specification.md
+
+**Note: These features are not currently supported in *const* collection
+literals. In a future release, we intend to relax this restriction and allow
+spread and collection `if` inside const collections.**
+
+### Core library changes
+
+#### `dart:isolate`
+
+* Added `debugName` property to `Isolate`.
+* Added `debugName` optional parameter to `Isolate.spawn` and
+ `Isolate.spawnUri`.
+
+#### `dart:core`
+
+* RegExp patterns can now use lookbehind assertions.
+* RegExp patterns can now use named capture groups and named backreferences.
+ Currently, named group matches can only be retrieved in Dart either by the
+ implicit index of the named group or by downcasting the returned Match
+ object to the type RegExpMatch. The RegExpMatch interface contains methods
+ for retrieving the available group names and retrieving a match by group
+ name.
+
+### Dart VM
+
+* The VM service now requires an authentication code by default. This behavior
+ can be disabled by providing the `--disable-service-auth-codes` flag.
+
+* Support for deprecated flags '-c' and '--checked' has been removed.
+
+### Dart for the Web
+
+#### dart2js
+
+A binary format was added to dump-info. The old JSON format is still available
+and provided by default, but we are starting to deprecate it. The new binary
+format is more compact and cheaper to generate. On some large apps we tested, it
+was 4x faster to serialize and used 6x less memory.
+
+To use the binary format today, use `--dump-info=binary`, instead of
+`--dump-info`.
+
+What to expect next?
+
+* The [visualizer tool][visualizer] will not be updated to support the new
+ binary format, but you can find several command-line tools at
+ `package:dart2js_info` that provide similar features to those in the
+ visualizer.
+
+* The command-line tools in `package:dart2js_info` also work with the old JSON
+ format, so you can start using them even before you enable the new format.
+
+* In a future release `--dump-info` will default to `--dump-info=binary`. At
+ that point, there will be an option to fallback to the JSON format, but the
+ visualizer tool will be deprecated.
+
+* A release after that, the JSON format will no longer be available from
+ dart2js, but may be available from a command-line tool in
+ `package:dart2js_info`.
+
+[visualizer]: https://dart-lang.github.io/dump-info-visualizer/
+
+### Tools
+
+#### dartfmt
+
+* Tweak set literal formatting to follow other collection literals.
+* Add support for "UI as code" features.
+* Properly format trailing commas in assertions.
+* Improve indentation of adjacent strings in argument lists.
+
+#### Linter
+
+The Linter was updated to `0.1.86`, which includes the following changes:
+
+* Added the following lints: `prefer_inlined_adds`,
+ `prefer_for_elements_to_map_fromIterable`,
+ `prefer_if_elements_to_conditional_expressions`,
+ `diagnostic_describe_all_properties`.
+* Updated `file_names` to skip prefixed-extension Dart files (`.css.dart`,
+ `.g.dart`, etc.).
+* Fixed false positives in `unnecessary_parenthesis`.
+
+#### Pub client
+
+* Added a CHANGELOG validator that complains if you `pub publish` without
+ mentioning the current version.
+* Removed validation of library names when doing `pub publish`.
+* Added support for `pub global activate`ing package from a custom pub URL.
+* Added subcommand: `pub logout`. Logs you out of the current session.
+
+#### Dart native
+
+Initial support for compiling Dart apps to native machine code has been added.
+Two new tools have been added to the `bin` folder of the Dart SDK:
+
+* `dart2aot`: AOT (ahead-of-time) compiles a Dart program to native
+machine code. The tool is supported on Windows, macOS, and Linux.
+
+* `dartaotruntime`: A small runtime used for executing an AOT compiled program.

+# Using Dart LSP in Vim
+
+## Prerequisites
+
+To use Dart’s LSP server with Vim you’ll need to be using at least version 2.2.0
+of the Dart SDK (which shipped in version 1.2.1 of Flutter). A Vim plugin manager
+is not required but may simplify setup. The steps below have been written assuming
+use of [vim-plug](https://github.com/junegunn/vim-plug).
+
+
+## Install the Plugins
+
+Install the [dart-vim-plugin](https://github.com/dart-lang/dart-vim-plugin) and
+[vim-lsc](https://github.com/natebosch/vim-lsc) plugins. Using vim-plug this can
+be done by adding the following to `.vimrc` then reloading and running
+`:PlugInstall`:
+
+```
+call plug#begin('~/.vim/plugged')
+Plug 'dart-lang/dart-vim-plugin'
+Plug 'natebosch/vim-lsc'
+call plug#end()
+```
+
+Note: Other LSP plugins are available for Vim but this document assumes vim-lsc.
+
+
+## Configure vim-lsc
+
+Next tell vim-lsc how to invoke the LSP server. You’ll need the path to the Dart
+SDK (which may be inside the Flutter SDK at bin/cache/dart-sdk for Flutter) and
+add this to `.vimrc` and reload.
+
+```
+let g:lsc_server_commands = {'dart': '~/dart-sdk/bin/dart ~/dart-sdk/bin/snapshots/analysis_server.dart.snapshot --lsp'}
+let g:lsc_auto_map = v:true " Use defaults
+```
+
+This will set up the LSP server for Dart files using default keybindings. More
+info on configuring vim-lsc can be found at
+[natebosch/vim-lsc#configuration](https://github.com/natebosch/vim-lsc#configuration).
+
+
+## Test the Plugins
+
+Open a Dart file in Vim and confirm that you see syntax highlighting (this is
+provided by dart-vim-plugin) and that invalid code is highlighted (this is
+provided by the LSP server via vim-lsc), with the error showing along the bottom
+of the window.
+
+
+## Keybindings and Commands
+
+Keybindings and commands are documented in the
+[vim-lsc README](https://github.com/natebosch/vim-lsc#configuration).
+
+
+## Supported Features
+
+Available features are those supported by both the vim-lsc plugin
+([see here](https://github.com/natebosch/vim-lsc#features)) and the Dart LSP
+server ([see here](https://github.com/dart-lang/sdk/blob/master/pkg/analysis_server/tool/lsp_spec/README.md#message-status)).
+
+
+## Troubleshooting
+
+If you find an issue with the LSP server you can enable logging in the server by
+adding the following switches to the LSP server command in `.vimrc`:
+
+```
+--instrumentation-log-file /path/to/logs/lsp-vim.txt
+```
+
+Issues should be opened in the [dart-lang/sdk](https://github.com/dart-lang/sdk)
+repository.

+## 0.36.0
+* Changed the return type of `Expression.precendence` to `Precedence`. Clients
+ that prepared for this change by switching to `Expression.precedence2` should
+ now return to using `Expression.precedence`.
+* AST cleanup related to the "UI as code" feature:
+ * Removed the following AST node types:
+ * `ForEachStatement` (use `ForStatement` instead)
+ * `MapLiteral` and `MapLiteral2` (use `SetOrMapLiteral` instead)
+ * `SetLiteral` and `SetLiteral2` (use `SetOrMapLiteral` instead)
+ * `ListLiteral2` (use `ListLiteral` instead)
+ * Deprecated `ForStatement2` (use `ForStatement` instead)
+ * Removed the following visit methods:
+ * `visitForEachStatement` (override `visitForStatement` instead)
+ * `visitMapLiteral` and `visitMapLiteral2` (override `visitSetOrMapLiteral`
+ instead)
+ * `visitSetLiteral` and `visitSetLiteral2` (override `visitSetOrMapLiteral`

+ * `visitListLiteral2` (override `visitListLiteral` instead)
+ * Deprecated the `visitForStatement2` visit method (use `VisitForStatement`
+ instead)

+ * `setLiteral` and `setLiteral2` (use `setOrMapLiteral` instead)
+ * `listLiteral2` (use `listLiteral` instead)
+ * Deprecated `AstFactory.forStatement2`, and introduced

+* Bug fixes: #36158, #36212, #36255
+
+## 0.35.4
+* Deprecated AST structures that will no longer be used after the
+ control_flow_collections and spread_collections experiments are enabled. The
+ following AST node types are deprecated:
+ * `ForEachStatement` (use `ForStatement2` instead)
+ * `ForStatement` (use `ForStatement2` instead)
+ * `MapLiteral` (use `SetOrMapLiteral` instead)

+ type will be changed to `Precedence`. Clients that wish to prepare for the
+ change can switch to `Expression.precedence2`.
+* Bug fixes: #35908, #35993 (workaround).
+
+## 0.35.2
+* Updated support in the AST structure for the control_flow_collections and
+ spread_collections experiments. The following methods are now deprecated:
+ * `AstFactory.mapLiteral2` and `AstFactory.setLiteral2` (replaced by
+ `AstFactory.setOrMapLiteral`).
+ * `AstVisitor.visitListLiteral2` (clients should not need to override this
+ anymore).
+ * `AstVisitor.visitMapLiteral2 and AstVisitor.visitSetLiteral2` (replaced by
+ `AstVisitor.visitSetOrMapLiteral`).
+* Started to add support for strict-inference as an analysis option.

+# Type Relation Test and Benchmarks
+
+This directory contains tests and benchmarks of type relations, for example,
+isSubtypeOf.
+
+## Create or Update Benchmark Data
+
+To collect new data for a benchmark, follow these steps:
+
+1. Identify the program that the benchmark is based on, for example,
+`pkg/compiler/bin/dart2js.dart`.
+
+2. Modify `pkg/kernel/lib/type_environment.dart` as described in the method
+`SubtypeTester._collect_isSubtypeOf`.
+
+3. Compile the program using Fasta, for example:
+
+ ./sdk/bin/dart pkg/front_end/tool/_fasta/compile.dart pkg/compiler/bin/dart2js.dart
+
+4. This produces a file named `type_checks.json` in the current directory.
+
+5. Compress the file using `gzip`.

-/// Script that updates kernel status lines automatically for tests under the

-///
-/// This script is hardcoded to only support this configuration and relies on
-/// a convention for how the status files are structured, In particular,
-/// every status file is expected to have these sections:
-///
-/// [ $compiler == dartk && $runtime == vm && $strong ]
-/// [ $compiler == dartk && $runtime == vm && $strong && $mode == debug ]
-/// [ $compiler == dartkp && $runtime == dart_precompiled && $strong ]
-/// [ $compiler == dartkp && $runtime == dart_precompiled && $strong && $mode == debug]
-///
-/// we allow other sections specifying $checked mode, but the script currently
-/// has not been configured to update them.
-///
-/// [ $compiler == dartk && $runtime == vm && $strong && $checked ]
-/// [ $compiler == dartk && $runtime == vm && $strong && !$checked ]
-/// [ $compiler == dartkp && $runtime == dart_precompiled && $strong && $checked]
-/// [ $compiler == dartkp && $runtime == dart_precompiled && $strong && !$checked]
-///
-/// Note that this script is brittle and will not work properly if there are
-/// other overlapping sections. If you see the script adding entries like "Pass"
-/// it is a sign that a test was broadly marked as failing in a more general
-/// section (e.g. $runtime == vm, but no compiler was specified).

# Garbage Collection
+The Dart VM has a generational garbage collector with two generations. The new generation is collected by a stop-the-world semispace [scavenger](https://github.com/dart-lang/sdk/blob/master/runtime/vm/heap/scavenger.h). The old generation is collected by concurrent-[mark](https://github.com/dart-lang/sdk/blob/master/runtime/vm/heap/marker.h)-concurrent-[sweep](https://github.com/dart-lang/sdk/blob/master/runtime/vm/heap/sweeper.h) or by concurrent-mark-parallel-[compact](https://github.com/dart-lang/sdk/blob/master/runtime/vm/heap/compactor.h).
+
## Object representation
+Object pointers refer either to immediate objects or heap objects, distinguished by a tag in the low bits of the pointer. The Dart VM has only one kind of immediate object, Smis (small integers), whose pointers have a tag of 0. Heap objects have a pointer tag of 1. The upper bits of a Smi pointer are its value, and the upper bits of a heap object pointer are the most signficant bits of its address (the least significant bit is always 0 because heap objects always have greater than 2-byte alignment).
+
+A tag of 0 allows many operations to be performed on Smis without untagging and retagging. It also allows hiding aligned addresses to the C heap from the GC.
+
+A tag of 1 has no penalty on heap object access because removing the tag can be folded into the offset used by load and store instructions.
+
+Heap objects are always allocated in double-word increments. Objects in old-space are kept at double-word alignment, and objects in new-space are kept offset from double-word alignment. This allows checking an object's age without comparing to a boundry address, avoiding restrictions on heap placement and avoiding loading the boundry from thread-local storage. Additionally, the scavenger can quickly skip over both immediates and old objects with a single branch.
+
+Heap objects have a single-word header, which encodes the object's class, size, and some status flags.
+
+On 64-bit architectures, the header of heap objects also contains a 32-bit identity hash field. On 32-bit architectures, the identity hash for heap objects is kept in a side table.
+
## Scavenge
+See [Cheney's algorithm](https://dl.acm.org/citation.cfm?doid=362790.362798).
+
## Mark-Sweep
## Mark-Compact
+The Dart VM includes a sliding compactor. The forwarding table is compactly represented by dividing the heap into blocks and for each block recording its target address and the bitvector for each surviving double-word. The table is accessed in constant time by keeping heap pages aligned so the page header of any object can be accessed by masking the object.
+
## Concurrent Marking
To reduce the time the mutator is paused for old-space GCs, we allow the mutator to continue running during most of the marking work.

+
+# Using FFI with Flutter
+
+## Android
+
+Before using the FFI on Android, you need to procure an Android-compatible build of the native library you want to link against.
+It's important that the shared object(s) be compatible with ABI version you wish to target (or else, that you have multiple builds for different ABIs).
+See [https://developer.android.com/ndk/guides/abis] for more details on Android ABIs.
+Within Flutter, the target ABI is controlled by the `--target-platform` parameter to the `flutter` command.
+
+The workflow for packaging a native library will depend significantly on the library itself, but to illustrate the challenges at play, we'll demonstrate how to build the SQLite library from source to use with the FFI on an Android device.
+
+### Building SQLite for Android
+
+Every Android device ships with a copy of the SQLite library (`/system/lib/libsqlite.so`).
+Unfortunately, this library cannot be loaded directly by apps (see [https://developer.android.com/about/versions/nougat/android-7.0-changes#ndk]).
+It is accessible only through Java.
+Instead, we can build SQLite directly with the NDK.
+
+First, download the SQLite "amalgamation" source from [https://www.sqlite.org/download.html].
+For the sake of brevity, we'll assume the file has been saved as `sqlite-amalgamation-XXXXXXX.zip`, the Android SDK (with NDK extension) is available in `~/Android`, and we're on a Linux workstation.
+
+```sh
+unzip sqlite-amalgamation-XXXXXXX.zip
+cd sqlite-amalgamation-XXXXXXX
+~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android24-clang -c sqlite3.c -o sqlite3.o
+~/Android/Sdk/ndk-bundle/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android-ld -shared sqlite3.o -o libsqlite3.so
+```
+
+Note the use of the `aarch64` prefix to the compiler: this indicates that we're building a shared object for the `arm64-v8a` ABI.
+This will be important later.
+
+### Update Gradle script
+
+Next we need to instruct Gradle to package this library with the app, so it will be available to load off the Android device at runtime.
+Create a folder `native-libraries` in the root folder of the app, and update the `android/app/build.gradle` file:
+
+```groovy
+android {
+ // ...
+ sourceSets {
+ main {
+ jniLibs.srcDir '${project.projectDir.path}/../../native-libraries'
+ }
+ }
+}
+```
+
+Within the `native-libraries` folder, the libraries are organized by ABI.
+Therefore, we must copy the compiled `libsqlite3.so` into `native-libraries/arm64-v8a/libsqlite3.so`.
+If multiple sub-directories are present, the libraries from the sub-directory corresponding to the target ABI will be available in the application's linking path, so the library can be loaded with `ffi.DynamicLibrary.open("libsqlite3.so")` in Dart.
+Finally, pass `--target-platform=android-arm64` to the `flutter` command when running or building the app since `libsqlite3.so` was compiled for the `arm64-v8a` ABI.

+# dart:ffi SQLite mini tutorial
+
+In this mini tutorial we learn how to bind SQLite, a native library, in Dart using Dart's new foreign function interface `dart:ffi`.
+We build a package which provides a Dartlike SQLite API using objects and `Iterator`s.
+Inside the package we write Dart code which directly invokes C functions and manipulates C memory.
+
+## Binding C Functions to Dart
+
+The first step is to load a Native Library:
+
+```dart
+import "dart:ffi";
+
+DynamicLibrary sqlite = dlopenPlatformSpecific("sqlite3");
+```
+
+In a `DynamicLibrary` we can `lookup` functions.
+Let's lookup the function `sqlite3_prepare_v2` in the SQLite library.
+That function has the following signature in the library header file.
+
+```c++
+SQLITE_API int sqlite3_prepare_v2(
+ sqlite3 *db, /* Database handle */
+ const char *zSql, /* SQL statement, UTF-8 encoded */
+ int nByte, /* Maximum length of zSql in bytes. */
+ sqlite3_stmt **ppStmt, /* OUT: Statement handle */
+ const char **pzTail /* OUT: Pointer to unused portion of zSql */
+);
+```
+
+In order to lookup a function, we need a _C signature_ and a _Dart signature_.
+
+```dart
+typedef sqlite3_prepare_v2_native_t = Int32 Function(
+ DatabasePointer database,
+ CString query,
+ Int32 nbytes,
+ Pointer<StatementPointer> statementOut,
+ Pointer<CString> tail);
+
+typedef Sqlite3_prepare_v2_t = int Function(
+ DatabasePointer database,
+ CString query,
+ int nbytes,
+ Pointer<StatementPointer> statementOut,
+ Pointer<CString> tail);
+```
+
+With these two signatures we can `lookup` the C function and expose it as a Dart function with `asFunction`.
+
+```dart
+Sqlite3_prepare_v2_t sqlite3_prepare_v2 = sqlite
+ .lookup<NativeFunction<sqlite3_prepare_v2_native_t>>("sqlite3_prepare_v2")
+ .asFunction();
+```
+
+Browse the code: [platform specific dynamic library loading](../lib/src/ffi/dylib_utils.dart), [C signatures](../lib/src/bindings/signatures.dart), [Dart signatures and bindings](../lib/src/bindings/bindings.dart), and [dart:ffi dynamic library interface](../../../../sdk/lib/ffi/dynamic_library.dart).
+
+## Managing C Memory
+
+In order to call `sqlite3_prepare_v2` to prepare a SQLite statement before executing, we need to be able to pass C pointers to C functions.
+
+Database and Statement pointers are opaque pointers in the SQLite C API.
+We specify these as classes extending `Pointer<Void>`.
+
+```dart
+class DatabasePointer extends Pointer<Void> {}
+class StatementPointer extends Pointer<Void> {}
+```
+
+Strings in C are pointers to character arrays.
+
+```dart
+class CString extends Pointer<Int8> {}
+```
+
+Pointers to C integers, floats, an doubles can be read from and written through to `dart:ffi`.
+However, before we can write to C memory from dart, we need to `allocate` some memory.
+
+```dart
+Pointer<Int8> p = allocate(); // Infers type argument allocate<Int8>(), and allocates 1 byte.
+p.store(123); // Stores a Dart int into this C int8.
+int v = p.load(); // Infers type argument p.load<int>(), and loads a value from C memory.
+```
+
+Note that you can only load a Dart `int` from a C `Int8`.
+Trying to load a Dart `double` will result in a runtime exception.
+
+We've almost modeled C Strings.
+The last thing we need is to use this `Pointer` as an array.
+We can do this by using `elementAt`.
+
+```dart
+CString string = allocate(count: 4).cast(); // Allocates 4 bytes and casts it to a string.
+string.store(73); // Stores 'F' at index 0.
+string.elementAt(1).store(73); // Stores 'F' at index 1.
+string.elementAt(2).store(70); // Stores 'I' at index 2.
+string.elementAt(3).store(0); // Null terminates the string.
+```
+
+We wrap the above logic of allocating strings in the constructor `CString.allocate`.
+
+Now we have all ingredients to call `sqlite3_prepare_v2`.
+
+```dart
+Pointer<StatementPointer> statementOut = allocate();
+CString queryC = CString.allocate(query);
+int resultCode = sqlite3_prepare_v2(
+ _database, queryC, -1, statementOut, fromAddress(0));
+```
+
+With `dart:ffi` we are responsible for freeing C memory that we allocate.
+So after calling `sqlite3_prepare_v2` we read out the statement pointer, and free the statement pointer pointer and `CString` which held the query string.
+
+```
+StatementPointer statement = statementOut.load();
+statementOut.free();
+queryC.free();
+```
+
+Browse the code: [CString class](../lib/src/ffi/cstring.dart), [code calling sqlite3_prepare_v2](../lib/src/database.dart#57), and [dart:ffi pointer interface](../../../../sdk/lib/ffi/ffi.dart).
+
+## Dart API
+
+We would like to present the users of our package with an object oriented API - not exposing any `dart:ffi` objects to them.
+
+The SQLite C API returns a cursor to the first row of a result after executing a query.
+We can read out the columns of this row and move the cursor to the next row.
+The most natural way to expose this in Dart is through an `Iterable`.
+We provide our package users with the following API.
+
+```dart
+class Result implements Iterable<Row> {}
+
+class Row {
+ dynamic readColumnByIndex(int columnIndex) {}
+ dynamic readColumn(String columnName) {}
+}
+```
+
+However, this interface does not completely match the semantics of the C API.
+When we start reading the next `Row`, we do no longer have access to the previous `Row`.
+We can model this by letting a `Row` keep track if its current or not.
+
+```dart
+class Row {
+ bool _isCurrentRow = true;
+
+ dynamic readColumnByIndex(int columnIndex) {
+ if (!_isCurrentRow) {
+ throw Exception(
+ "This row is not the current row, reading data from the non-current"
+ " row is not supported by sqlite.");
+ }
+ // ...
+ }
+}
+```
+
+A second mismatch between Dart and C is that in C we have to manually release resources.
+After executing a query and reading its results we need to call `sqlite3_finalize(statement)`.
+
+We can take two approaches here, either we structure the API in such a way that users of our package (implicitly) release resources, or we use finalizers to release resources.
+In this tutorial we take the first approach.
+
+If our users iterate over all `Row`s, we can implicitly finalize the statement after they are done with the last row.
+However, if they decide they do not want to iterate over the whole result, they need to explicitly state this.
+In this tutorial, we use the `ClosableIterator` abstraction for `Iterators` with backing resources that need to be `close`d.
+
+```dart
+Result result = d.query("""
+ select id, name
+ from Cookies
+ ;""");
+for (Row r in result) {
+ String name = r.readColumn("name");
+ print(name);
+}
+// Implicitly closes the iterator.
+
+result = d.query("""
+ select id, name
+ from Cookies
+ ;""");
+for (Row r in result) {
+ int id = r.readColumn("id");
+ if (id == 1) {
+ result.close(); // Explicitly closes the iterator, releasing underlying resources.
+ break;
+ }
+}
+```
+
+Browse the code: [Database, Result, Row](../lib/src/database.dart), and [CloseableIterator](../lib/src/collections/closable_iterator.dart).
+
+## Architecture Overview
+
+The following diagram summarized what we have implemented as _package developers_ in this tutorial.
+
+
+
+As the package developers wrapping an existing native library, we have only written Dart code - not any C/C++ code.
+We specified bindings to the native library.
+We have provided our package users with an object oriented API without exposing any `dart:ffi` objects.
+And finally, we have implemented the package API by calling the C API.
+
+## Current dart:ffi Development Status
+
+In this minitutorial we used these `dart:ffi` features:
+
+* Loading dynamic libararies and looking up C functions in these dynamic libraries.
+* Calling C functions, with `dart:ffi` automatically marshalling arguments and return value.
+* Manipulating C memory through `Pointer`s with `allocate`, `free`, `load`, `store`, and `elementAt`.
+
+Features which we did not use in this tutorial:
+
+* `@struct` on subtypes of `Pointer` to define a struct with fields. (However, this feature is likely to change in the future.)
+
+Features which `dart:ffi` does not support yet:
+
+* Callbacks from C back into Dart.
+* Finalizers
+* C++ Exceptions (Not on roadmap yet.)
+
+Platform limitations:
+
+* `dart:ffi` is only enabled on 64 bit Windows, Linux, and MacOS. (Arm64 and 32 bit Intel are under review.)
+* `dart:ffi` only works in JIT mode, not in AOT.
+
+It is possible to work around some of the current limitations by adding a C/C++ layer.
+For example we could catch C++ exceptions in a C++ layer, and rethrow them in Dart.
+The architecture diagram would change to the following in that case.

+/// Database Connection Handle
+///
+/// Each open SQLite database is represented by a pointer to an instance of
+/// the opaque structure named "sqlite3". It is useful to think of an sqlite3
+/// pointer as an object. The [sqlite3_open()], [sqlite3_open16()], and
+/// [sqlite3_open_v2()] interfaces are its constructors, and [sqlite3_close()]
+/// is its destructor. There are many other interfaces (such as
+/// [sqlite3_prepare_v2()], [sqlite3_create_function()], and
+/// [sqlite3_busy_timeout()] to name but three) that are methods on an
+class DatabasePointer extends Pointer<Void> {}
+
+/// SQL Statement Object
+///
+/// An instance of this object represents a single SQL statement.
+/// This object is variously known as a "prepared statement" or a
+/// "compiled SQL statement" or simply as a "statement".
+///
+/// The life of a statement object goes something like this:
+///
+/// <ol>
+/// <li> Create the object using [sqlite3_prepare_v2()] or a related
+/// function.
+/// <li> Bind values to [host parameters] using the sqlite3_bind_*()
+/// interfaces.
+/// <li> Run the SQL by calling [sqlite3_step()] one or more times.
+/// <li> Reset the statement using [sqlite3_reset()] then go back
+/// to step 2. Do this zero or more times.
+/// <li> Destroy the object using [sqlite3_finalize()].
+/// </ol>
+///
+/// Refer to documentation on individual methods above for additional
+/// information.
+class StatementPointer extends Pointer<Void> {}
+
+/// Dynamically Typed Value Object
+///
+/// SQLite uses the sqlite3_value object to represent all values
+/// that can be stored in a database table. SQLite uses dynamic typing
+/// for the values it stores. ^Values stored in sqlite3_value objects
+/// can be integers, floating point values, strings, BLOBs, or NULL.
+///
+/// An sqlite3_value object may be either "protected" or "unprotected".
+/// Some interfaces require a protected sqlite3_value. Other interfaces
+/// will accept either a protected or an unprotected sqlite3_value.
+/// Every interface that accepts sqlite3_value arguments specifies
+/// whether or not it requires a protected sqlite3_value.
+///
+/// The terms "protected" and "unprotected" refer to whether or not
+/// a mutex is held. An internal mutex is held for a protected
+/// sqlite3_value object but no mutex is held for an unprotected
+/// sqlite3_value object. If SQLite is compiled to be single-threaded
+/// (with [SQLITE_THREADSAFE=0] and with [sqlite3_threadsafe()] returning 0)
+/// or if SQLite is run in one of reduced mutex modes
+/// [SQLITE_CONFIG_SINGLETHREAD] or [SQLITE_CONFIG_MULTITHREAD]
+/// then there is no distinction between protected and unprotected
+/// sqlite3_value objects and they can be used interchangeably. However,
+/// for maximum code portability it is recommended that applications
+/// still make the distinction between protected and unprotected
+/// sqlite3_value objects even when not strictly required.
+///
+/// ^The sqlite3_value objects that are passed as parameters into the
+/// implementation of [application-defined SQL functions] are protected.
+/// ^The sqlite3_value object returned by
+/// [sqlite3_column_value()] is unprotected.
+/// Unprotected sqlite3_value objects may only be used with
+/// [sqlite3_result_value()] and [sqlite3_bind_value()].
+/// The [sqlite3_value_blob | sqlite3_value_type()] family of
+/// interfaces require protected sqlite3_value objects.

- * The created map is not ordered in any way. When iterating the keys or
- * values, the iteration order is unspecified except that it will stay the
- * same as long as the map isn't changed.
- *
- * If [equals] is provided, it is used to compare the keys in the table with
- * new keys. If [equals] is omitted, the key's own [Object.==] is used
- * instead.
- *
- * Similar, if [hashCode] is provided, it is used to produce a hash value
- * for keys in order to place them in the hash table. If it is omitted, the
- * key's own [Object.hashCode] is used.
- *
- * If using methods like [operator []], [remove] and [containsKey] together
- * with a custom equality and hashcode, an extra `isValidKey` function
- * can be supplied. This function is called before calling [equals] or
- * [hashCode] with an argument that may not be a [K] instance, and if the
- * call returns false, the key is assumed to not be in the set.
- * The [isValidKey] function defaults to just testing if the object is a
- * [K] instance.
- *
- * Example:
- *
- * new HashMap<int,int>(equals: (int a, int b) => (b - a) % 5 == 0,
- * hashCode: (int e) => e % 5)
- *
- * This example map does not need an `isValidKey` function to be passed.
- * The default function accepts only `int` values, which can safely be
- * passed to both the `equals` and `hashCode` functions.
- *
- * If neither `equals`, `hashCode`, nor `isValidKey` is provided,
- * the default `isValidKey` instead accepts all keys.
- * The default equality and hashcode operations are assumed to work on all
- * objects.
- *
- * Likewise, if `equals` is [identical], `hashCode` is [identityHashCode]
- * and `isValidKey` is omitted, the resulting map is identity based,
- * and the `isValidKey` defaults to accepting all keys.
- * Such a map can be created directly using [HashMap.identity].
- *
- * The used `equals` and `hashCode` method should always be consistent,
- * so that if `equals(a, b)` then `hashCode(a) == hashCode(b)`. The hash
- * of an object, or what it compares equal to, should not change while the
- * object is a key in the map. If it does change, the result is unpredictable.
- *
- * If you supply one of [equals] and [hashCode],
- * you should generally also to supply the other.
