[tfa] Fix bug in TFA transformation of unused fields

When a TFA eliminates a field it moves it's initializer to a
`LocalInitializer` of the constructor. After [0] the
`VariableDeclaration` of the local initializer will get the type of the
field.

Though that CL didn't ensure TFA also visits the type of the
`VariableDeclaration`. This can lead to a situation where the type
refers to a class that TFA has tree shaken, which causes dangling
references in the AST.

Dart

An approachable, portable, and productive language for high-quality apps on any platform

Dart is:

  • Approachable: Develop with a strongly typed programming language that is consistent, concise, and offers modern language features like null safety and patterns.

  • Portable: Compile to ARM, x64, or RISC-V machine code for mobile, desktop, and backend. Compile to JavaScript or WebAssembly for the web.

  • Productive: Make changes iteratively: use hot reload to see the result instantly in your running app. Diagnose app issues using DevTools.

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).
