Example

❌ Bad:

typedef NullableRecord = ((({String str, Future<void> hello}),),); // LINT

(int, (int, (int,))) triple() => (...); // LINT

(int, (int, (int, (int,)))) quadruple() => (...); // LINT

✅ Good:

typedef NullableRecord = ({String str, Future<void> hello});

(int, int, int) triple() => (...);

(int, int, int, int) quadruple() => (...);
