[linter] Primary constructors - Add lint 'var_with_no_type_annotation' This new lint fires when a formal parameter is declared with `var` and no type annotation. We're adding this lint to ease the migration for when primary constructors is enabled. Adding a quick-fix for this lint will come in a follow-up CL. Tests: - Class methods, extension methods, extension type methods, mixin methods, constructors, setters, functions - Initializing formals - Super parameters - Function typed parameters - Named parameters, positional parameters, optional parameters, required parameters, Bug: https://github.com/dart-lang/sdk/issues/61591 Change-Id: Ib09c87e234cde4be024af0b9d8a1e3e0a371e777 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/481620 Commit-Queue: Kallen Tu <kallentu@google.com> Reviewed-by: Brian Wilkerson <brianwilkerson@google.com>
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.
