Migration: Replace `?.` with `.` when target already migrated.

With this change, the migration tool no longer warns "Null-aware
access will be unnecessary in strong checking mode" for the specific
case where the target of a null-aware access is a non-nullable method
or getter invocation, and the method or getter in question is in
already-migrated code.  The whole point of the warning is to help the
user identify situations where the migration tool might have made the
wrong decision about code that it's currently migrating; that's not
useful if the method or getter was migrated previously.  So instead,
in these circumstances, the migration tool simply changes `?.` to `.`.

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).
