[Class modifiers] The Function class will be final in Dart 3.0

[lrhn]

In pre-3.0 code the Function class can be implemented, extended and (probably) mixed in, it's just ignored and has absolutely no effect.
In 3.0 code, the Function class will have a final modifier which prevents all of the above.

The following tests seem to be affected by that (according to a grep):

Language/Expressions/Method_Invocation/Ordinary_Invocation/accessible_instance_member_t07.dart:class A extends Function {
Language/Expressions/Method_Invocation/Ordinary_Invocation/accessible_instance_member_t08.dart:class A extends Function {

If there are more examples (didn't find any implements?) or ones that go through indirections, say something like implements IdAlias<Function> with typedef IdAlias<T> = T;, then they might also need fixing.

@mit-mit the log is unavailable for me. Could you, please, provide a link to the gerrit CL?

[mit-mit]

Sorry about that. It's here: https://dart-review.googlesource.com/c/sdk/+/284185?tab=checks

And the test results: https://ci.chromium.org/ui/p/dart/builders/try/analyzer-linux-release-try/63852/overview
