Linter rule request - Avoid Bang operator

[har5hit]

Hello,

I would like to request a lint rule to avoid bang operator usage,

For ex:

String? a;
String b = a!;  // Should not be allowed

Developer should be forced to use,
String b = a ?? "default";

They can also create a scoped extension like kotlin for complex cases like,

extension ObjectExt<T> on T {
  R let<R>(R Function(T item) op) => op(this);
}

String b = a?.let((item) => "Hello $a") ?? "Hello Default";

Thank you

Right! We've discussed something similar before and are tracking the idea in #58535.

Feel free to add any more context there.

Thanks!
