+The analysis server snapshot is included in the `bin/snapshots` folder of the Dart SDK. Pass the `--lsp` flag to start the server in LSP mode and the `--client-id` and `--client-version` flags to identify your editor/plugin and version:
```
-dart bin/snapshots/analysis_server.dart.snapshot --lsp
+dart bin/snapshots/analysis_server.dart.snapshot --lsp --client-id my-editor.my-plugin --client-version 1.2
```
Note: In LSP the client makes the first request so there is no obvious confirmation that the server is working correctly until the client sends an `initialize` request. Unlike standard JSON RPC, [LSP requires that headers are sent](https://microsoft.github.io/language-server-protocol/specification).

-/// This part contains helpers for supporting runtime type information.
-///
-/// The helper use a mixture of Dart and JavaScript objects. To indicate which
-/// is used where we adopt the scheme of using explicit type annotation for Dart
-/// objects and 'var' or omitted return type for JavaScript objects.
-///
-/// Since bool, int, and String values are represented by the same JavaScript
-/// primitives, type annotations are used for these types in all cases.
-///
-/// Several methods use a common JavaScript encoding of runtime type
-/// information. This encoding is referred to as the type representation which
-/// is one of these:
-/// 1) a JavaScript constructor for a class C: the represented type is the raw
-/// type C.
-/// 2) a JavaScript array: the first entry is of type 1 and contains the
-/// subtyping flags and the substitution of the type and the rest of the
-/// array are the type arguments.
-/// 3) `null`: the dynamic type.
-/// 4) a JavaScript object representing the function type. For instance, it has
-/// the form {ret: rti, args: [rti], opt: [rti], named: {name: rti}} for a
-/// function with a return type, regular, optional and named arguments.
-/// Generic function types have a 'bounds' property.
-///
-/// To check subtype relations between generic classes we use a JavaScript
-/// expression that describes the necessary substitution for type arguments.
-/// Such a substitution expression can be:
-/// 1) `null`, if no substituted check is necessary, because the
-/// type variables are the same or there are no type variables in the class
-/// that is checked for.
-/// 2) A list expression describing the type arguments to be used in the
-/// subtype check, if the type arguments to be used in the check do not
-/// depend on the type arguments of the object.
-/// 3) A function mapping the type variables of the object to be checked to a
-/// list expression. The function may also return null, which is equivalent
-/// to an array containing only null values.

+// Interpolation calls `toString`.
+// The evaluation of the interpolation fails if `toString` throws or returns
+// null. In Dart 2, any method overriding `Object.toString` must return a
+// `String` or `null`. In particular, if `object.toString()` returns null, then
+// `"$object"` must not evaluate to the string `"null"`.
+//
+// The specification states that the expression of an interpolation is
+// evaluated as follows:
+//
+// 1. Evaluate $e_i$ to an object $o_i$.
+// 2. Invoke the `toString` method on *o<sub>i</sub>* with no arguments,
+// and let *r<sub>i</sub>*$ be the returned value.
+// 3. If *r<sub>i</sub>* is not an instance of the built-in type `String`,
+// throw an `Error`.
+//
+// (Then the resulting strings are concatenated with the literal string parts).
+//
+//
+// Adding an object to a `StringBuffer` behaves the same as evaluating
+// an expression in an interpolation. It must immediately fail if the
+// object's toString throws or returns `null`.
+//
+// This ensures that implementing interpolation via a `StringBuffer`is
