Dart Best Practices (P1)

• Scoping:
  • No global variables.
  • Private globals (if required) must start with _.
• Immutability: Use const > final > var.
• Config: Use --dart-define for secrets. Never hardcode API keys.
• Naming: Follow effective-dart (PascalCase classes, camelCase members).

import 'models/user.dart'; // Good
import 'package:app/models/user.dart'; // Avoid local absolute
