Reland: [cfe] Embed and use allowed experiments in CFE This CL embeds the sdk_nnbd/lib/_internal/allowed_experiments.json into the CFE and uses this to allow experiments enabled on a per library basis. The file is embedded through generated code to avoid reliance on access to the file itself. A presubmit check is also added to ensure that the json file and the generated code are in sync. This work is in preparation for https://github.com/dart-lang/sdk/issues/41538 This was reverted in https://dart-review.googlesource.com/c/sdk/+/149620 because flutter wasn't prepared for auto-enabling nnbd in dart:* libraries. This has now been fixed in https://github.com/flutter/engine/pull/18714 Closes #42162 Change-Id: I686ed6feaef8ee066b426068fe2a0f5080bf1713 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/149588 Reviewed-by: Jens Johansen <jensj@google.com> Commit-Queue: Johnni Winther <johnniwinther@google.com>
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).
Dart is free and open source.
