This CL removes some duplication of Strings: * Most duplication in `relevanceTagsInFile` (`ElementKind.CLASS`, etc) when loaded from file. * Usage of `()` for `parameters`. * Empty string return type. * Known type return type. On the analyzer instance I've measured on (8 folders with analyzer etc open) this saves: Before CL: 161851 kb 2158725 _OneByteString dart:core 1: 154622 kb 2001695 _OneByteString dart:core // removes most practical duplication from relevanceTagsInFile 2: 153247 kb 1957751 _OneByteString dart:core // Removes () parameters 3: 152970 kb 1939890 _OneByteString dart:core // Removes empty string return type 3: 151287 kb 1886063 _OneByteString dart:core // removes void, String, bool, int, Future<void> return type That's a total of 10,564 kb or 272,662 instances. This is also ~1.7% of total ram usage.

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).
License & patents
Dart is free and open source.
