Dart Shorthand

Use Dart dot shorthand syntax when the surrounding context type is clear and the shorter form improves readability.

Official reference: https://dart.dev/language/dot-shorthands

When to Use This Skill

• Writing Dart 3.11+ code
• Refactoring repetitive enum prefixes such as MyEnum.value
• Initializing typed fields or locals with constructors like .new() or .origin()
• Using static members where the target type is obvious from context
• Reviewing code for shorthand opportunities without reducing clarity

Preferred Uses

• Enum values in assignments, arguments, collection literals, and switch expressions
• Named and unnamed constructors when the variable, field, or return type is explicit
• Static methods and getters when the expected type is unambiguous

Examples

enum Status { idle, loading, success, failure }

Status status = .idle;

switch (status) {
  case .idle:
  case .loading:
  case .success:
  case .failure:
}

final ScrollController controller = .new();
final GlobalKey<FormState> formKey = .new();

int port = .parse('8080');
