Flow analysis: replace context toString methods with a less fragile mechanism. Adds getters `_debugFields` and `_debugType` to the `_FlowContext` base class, and adds a single implementation of `_FlowContext.toString` that builds a representation of the context based on them. This replaces the implementations of `toString` in all the classes derived from `_FlowContext`, which were more difficult to get right and keep synchronized with code changes. Also changes `_TryFinallyContext` from a `late final` variable to a nullable variable. This sacrifices a tiny bit of safety, but has the advantage of allowing `toString` to show the value if it's been initialized, and avoid crashing if it hasn't.

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.
