Revert "[dart2wasm] Fix runtime type tests" This reverts commit a289c4d84870d9d403307535d281f2f8fc79c2f5. Reason for revert: https://github.com/flutter/flutter/issues/124282 Original change's description: > [dart2wasm] Fix runtime type tests > > emitTypeTest optimizes a test like `x is List<T>` where `x : > Iterable<T>`, i.e. tested-against type is a subtype of the operand's > static type. In these cases we can check just the class ID of the > operand without checking the type arguments. > > However this optimization cannot be done when the types don't have same > number of type arguments. Example: > > class H1<T> {} > > bool test(Object o) { > return o is H1<num>; > } > > void main() { > print(test(H1<Object>())); > } > > Here `H1<num> <: Object`, but we still need to check the type parameter. > > This CL checks that the types have the same number of type arguments > before optimizing the test. > > Fixes #51187. > > This fix reveals another bug in `static_interop_test`, which is tracked > in #51200. The test is updated to work around the bug for now. > > New passing tests: > > - co19/LanguageFeatures/Patterns/matching_cast_A01_t01 > - co19/LanguageFeatures/Patterns/matching_list_A01_t01 > - co19/LanguageFeatures/Patterns/matching_list_A01_t02 > - co19/LanguageFeatures/Patterns/matching_object_A01_t01 > - co19/LanguageFeatures/Patterns/matching_object_A01_t02 > - co19/LanguageFeatures/Patterns/record_A01_t03 > - co19/LanguageFeatures/Patterns/record_A01_t06 > - co19/LanguageFeatures/Patterns/record_A01_t07 > - co19/LanguageFeatures/Patterns/record_A01_t08 > - co19/LanguageFeatures/Patterns/record_A01_t09 > - language/generic/deep_test > - language/generic_methods/type_expression_test > - language/patterns/object_pattern_inference_test > > Change-Id: Ibd9615666b7f7538c2a3f03fb7f5ebe9b16c3d54 > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/292881 > Reviewed-by: Joshua Litt <joshualitt@google.com> > Commit-Queue: Ömer Ağacan <omersa@google.com> Change-Id: Ieb222c086864744d33b77de69882e805981f1953 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/293891 Commit-Queue: Zach Anderson <zra@google.com> Bot-Commit: Rubber Stamper <rubber-stamper@appspot.gserviceaccount.com> Reviewed-by: Joshua Litt <joshualitt@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.
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.
