Revert "[vm/compiler] Optimize switch statements" This reverts commit f5228127f8570be359c2645b8c315bfafe9b0ce3. Reason for revert: causes a VM crash, see b/242964932 (the test is also publicly available at https://github.com/simolus3/drift/blob/93fb0da38a5f33c8db289bfde696b0ca3d401b7f/drift_dev/test/analyzer/sql_queries/query_analyzer_test.dart#L8) Original change's description: > [vm/compiler] Optimize switch statements > > Switch statements that either contain only integers or only enum values of the same type can be optimized. > > Depending on the number of switch expressions and the number of holes that the range of switch expressions contains, either a binary search or a jump table is used. > > TEST=runtime/test/vm/dart{,_2}/optimized_switch > TEST=tests/language{,_2}/switch > > Fixes: https://github.com/dart-lang/sdk/issues/49585 > > Co-authored-by: Gabriel Terwesten gabriel@terwesten.net > > Change-Id: I62dcdb7843107f03de7e468c60b4db52ec78f676 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/253787 > Reviewed-by: Alexander Markov <alexmarkov@google.com> > Commit-Queue: Alexander Markov <alexmarkov@google.com> TBR=vegorov@google.com,alexmarkov@google.com,gabriel@terwesten.net Change-Id: I8c673ea70e7ed91dffb3674e7dcb4aaa0611e978 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/255258 Reviewed-by: Slava Egorov <vegorov@google.com> Reviewed-by: Ilya Yanok <yanok@google.com> Commit-Queue: Slava Egorov <vegorov@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.

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.
