Revert "[dart2wasm] Use DataView in JS typed arrays" This reverts commit b9b7de14e0b2871a8a6f2f2a0d0c1d236b8c4fe1. Reason for revert: Dart to Engine rolls are failing, please see https://github.com/flutter/engine/runs/18494538711 Original change's description: > [dart2wasm] Use DataView in JS typed arrays > > Refcator JS typed array classes to store JS `DataView`s (instead of JS > typed array with the matching type), and use V8's new optimized > `DataView` imports. > > Brings JS typed array class performance from unusable to reasonable > levels. In `SkeletalAnimation` benchmark: > > - Before: 1444 us. > - After: 101 us. > > Future work: > > - Make immutable classes extend the mutable ones. This will allow `[]` > calls to be always inlined in JSCM. > > - Move list mixin applications from the base class to implementation > classes. This will allow members like `elementAt`, `forEach` etc. to > have direct calls to other methods of the same class. > > - Try adding a `length` field to avoid JS calls in bounds checks. > > Change-Id: Ief6165fe9c4a825072077db820b105c4fca30dce > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/328920 > Reviewed-by: Aske Simon Christensen <askesc@google.com> > Commit-Queue: Ömer Ağacan <omersa@google.com> Change-Id: Iba46cfc409805bcd6f86bcc52a06ed8d54eea671 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/335026 Reviewed-by: Alexander Aprelev <aam@google.com> Commit-Queue: Siva Annamalai <asiva@google.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.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.
See LICENSE and PATENT_GRANT.

Browse pub.dev for more packages and libraries contributed by the community and the Dart team.
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 on our wiki.
The easiest way to contribute to Dart is to file issues.
You can also contribute patches, as described in Contributing.
