Suggests using dot shorthands with static fields.

When a static field type matches the type of its class, such fields can be used as dot shorthands (without an explicit class prefix).

Example​

❌ Bad:

void fn(SomeClass? e) {
  switch (e) {
    // LINT: Prefer dot shorthands instead of explicit class prefixes. Try removing the prefix.
    case SomeClass.first:
      print(e);
  }

  final v = switch (e) {
    // LINT: Prefer dot shorthands instead of explicit class prefixes. Try removing the prefix.
    SomeClass.first => 1,
    _ => 2,
  };

  // LINT: Prefer dot shorthands instead of explicit class prefixes. Try removing the prefix.
  final SomeClass another = SomeClass.first;

  // LINT: Prefer dot shorthands instead of explicit class prefixes. Try removing the prefix.
  if (e == SomeClass.first) {}
}

// LINT: Prefer dot shorthands instead of explicit class prefixes. Try removing the prefix.
void another({SomeClass value = SomeClass.first}) {}

// LINT: Prefer dot shorthands instead of explicit class prefixes. Try removing the prefix.
SomeClass getClass() => SomeClass.first;

class SomeClass {
  final String value;

  const SomeClass(this.value);

  static const first = SomeClass('first');
  static const second = SomeClass('second');
}

✅ Good:

void fn(SomeClass? e) {
  switch (e) {
    case .first:
      print(e);
  }

  final v = switch (e) {
    .first => 1,
    _ => 2,
  };

  final SomeClass another = .first;

  if (e == .first) {}
}

void another({SomeClass value = .first}) {}

SomeClass getClass() => .first;

Object getObject() => SomeClass.first;
