Cache the WidgetCreatorTracker. This fixes the problem when the flutter bots run multiple tests from the flutter tool e.g., flutter test first_widget_test.dart second_widget_test.dart The first test causes the set of libraries, particularly Flutter's framework library, to be passed to the transformer. The transformer needs the 'Widget' class located in Flutter's framework library. The transformer on the first test works. Each subsequent test only the libraries not in the prior test are passed, without the framework library, the transformer is unable to find the 'Widget' class and the widget transformer fails to run. This fix allows the use of a nice speedup to hot-reloading Flutter applications when --track-widget-creation is enabled and it allows us to enable --track-widget-creation by default, for command line Flutter users.

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).
Dart is free and open source.
