Warns when a cascade expression is being returned from a function.

Returning cascade expressions can add additional confusion to the code reader as to what is actually being returned.

Example​

❌ Bad:

class Cow {
  void moo() {}
}

Cow getCow() {
  return Cow..moo(); // LINT: Avoid returning cascade expressions. Try declaring a variable separately and returning it instead.
}

✅ Good:

Cow getAnotherCow() {
  final cow = Cow();
  cow.moo();

  return cow;
}
