[dart2js] Include block statements as potentially captured scopes. Some scopes that are capturable by closures are not getting marked as such. Instead the parent scope (e.g. the enclosing member) is being treated as the captured scope that owns all the variable declarations down to the closure. The scopes are then being shared across different closures and variables with the same name are able to be overwritten. This bug occurs for any block that isn't a loop or function (i.e. raw blocks, if blocks, try blocks). Loops are correctly handled as defining a scope and therefore those already work correctly. Note: This may cause some small code size increase. There may now be extra assignements reseting capture boxes in more scopes.

Dart is:
Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.
Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.
Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.
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).
Dart is free and open source.
