That forces them to be nullable, unless there is a reason to be non-nullable. I excluded setters and generic arguments from this nullification. Also we don't touch `operator ==`, where changing argument type to `Object?` doesn't make sense. This is a response to some teams asking for the migration tool to be super conservative. Otherwise people migrate some methods to have non-nullable arguments and they are still called with `null`s at runtime in mixed mode. That was the only way I found to implement the "nullable arguments by default" request. It broke a good deal of tests. I updated them mostly to use private functions, so the old behavior is preserved, but sometimes I couldn't figure out a way to trigger the desired codepath with the new behavior... I also suspect that now there is a non-zero amount of tests that are passing but don't really exercise what they were supposed to exercise.

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).
