Previously, each piece of analyzer code needed during the FixBuilder stage of migration needed to use the ElementTypeProvider interface to access element types (rather than reading the types from the elements directly), in order to ensure that the proper post-migration types were used when building fixes. This required a lot of plumbing, and there was a high risk that we would accidentally fail to use the indirection mechanism in a key location and access the elements directly. This CL changes the approach so that the ElementImpl classes themselves are responsible for indirecting through ElementTypeProvider. This means that we can back out all the plumbing, and there is no risk of accidentally failing to use the indirection mechanism.

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 has 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).
