Describe the bug
Switch case folding doesn't fold until the next case if a function has parameters that span multiple lines (I think that is the issue, but maybe something similar at least?).

To Reproduce
Add a file with this sample:

Future<void> f() async {
  switch (1) {
    case 1:
      print('something');
      someBigFunctionName(
        someReallyReallyLongNameHereSoItHasToSplit: 1234567,
      );
    case 2:
      print('another thing');
      print('yet another thing');
    case 3:
      print('more things');
  }
}
void someBigFunctionName({
  int? someReallyReallyLongNameHereSoItHasToSplit,
}) {}

Try to fold at case 1 and see that it doesn't fold someBigFunctionName.

Expected behavior
It folds someBigFunctionName.
