![]() For each selector, count the number of calls to the selector that are both reachable and polymorphic according to the TFA. Only include selectors in the table with non-zero counts. This reduces the dispatch table size by 30% in dart2js and by 49% in Flutter Gallery (312k memory use reduction on ARM64). Call counts are transferred in a dedicated metadata block with per-selector information. This mechanism also prepares for transferring other per-selector information in the future.

Dart
A client-optimized language for fast apps on any platform
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.
