Additional test cases in support of record/variable pattern disambiguation. Two of these tests (`recordPattern_nullable_beforeAs` and `recordPattern_nullable_beforeWhen`) verify that the fix for #52439 (Destructuring with explicit type of nullable record is a parsing error), which causes `(...)? identifier` to be recognized as a variable pattern, doesn't get confused by the pseudo-identifiers `as` and `when`, and so it continues to correctly parse `(...)? as ...` as a cast pattern and `(...)? when ...` as a guarded pattern. The other two tests (`recordPattern_nonNullable_beforeAs` and `recordPattern_nonNullable_beforeWhen`) verify that `(...) as ...` and `(...) when ...` are parsed correctly. These forms were never broken, but they were not well tested either.

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.
