preset: recommended

Warns when a switch on the Enum value has a wildcard pattern case.

Example

❌ Bad:

enum MyEnum { first, second }

void someFn() {
  final value = MyEnum.first;

  final result = switch (value) {
    MyEnum.first => 1,
    _ => 2, // LINT
  };
}

✅ Good:

enum MyEnum { first, second }

void someFn() {
  final value = MyEnum.first;

  final result = switch (value) {
    MyEnum.first => 1,
    MyEnum.second => 2,
  };
}
