Johnni Winther f26c0e2056 [cfe] Add explicit type argument to .map(...).toList()
Expressions like

  List<VariableDeclaration> variables = ...
  List<Expression> reads = variables.map((v) => VariableGet(v)).toList()

don't get the intended type argument `<Expression>` through inference,
but instead the type inferred from the return type of the closure, in
this case `<VariableGet>`.

This causes problems when used with the AST which assumes that
expressions are interchangeable wherever they are used, and is likely
the cause of https://github.com/flutter/flutter/issues/102077 .

This CL adds an explicit type argument in these cases.

Dart

A client-optimized language for fast apps on any platform

Dart is:

  • Optimized for UI: Develop with a programming language specialized around the needs of user interface creation.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app.

  • Fast on all platforms: Compile to ARM & x64 machine code for mobile, desktop, and backend. Or compile to JavaScript for the web.

Dart's flexible compiler technology lets you run Dart code in different ways, depending on your target platform and goals:

  • Dart Native: For programs targeting devices (mobile, desktop, server, and more), Dart Native includes both a Dart VM with JIT (just-in-time) compilation and an AOT (ahead-of-time) compiler for producing machine code.

  • Dart Web: For programs targeting the web, Dart Web includes both a development time compiler (dartdevc) and a production time compiler (dart2js).
