Revert "[vm, compiler] Treat _uninitializedData/Index as effectively const." This reverts commit 562af5de3562584dd15a115d27808cfb14eefc85. Reason for revert: regression, loses exact type for initial value? Original change's description: > [vm, compiler] Treat _uninitializedData/Index as effectively const. > > This avoids static field initialization checks in the default map and set constructors, which in turn avoids write barriers and the frame build. > > TEST=ci > Change-Id: Ie12840ae1799cd97645b2132ad94ec6525126f74 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/398760 > Reviewed-by: Alexander Markov <alexmarkov@google.com> > Commit-Queue: Ryan Macnak <rmacnak@google.com> Change-Id: I41af0247277f6456ba9c5dfcdb8da43cebc64cc0 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/400222 Commit-Queue: Siva Annamalai <asiva@google.com> Reviewed-by: Siva Annamalai <asiva@google.com> Auto-Submit: Ryan Macnak <rmacnak@google.com> Reviewed-by: Ryan Macnak <rmacnak@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.
See LICENSE and PATENT_GRANT.

Our API reference documentation is published at api.dart.dev, based on the stable release. (We also publish docs from our beta and dev channels, as well as from the primary development branch).
If you want to build Dart yourself, here is a guide to getting the source, preparing your machine to build the SDK, and building.
There are more documents in our repo at docs.
The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
Future plans for Dart are included in the combined Dart and Flutter roadmap on the Flutter wiki.
