prefer_const_declarations
Forces the use of const whenever possible.
π§ Example: const myValue = 10;
π‘ Improves performance, especially during widget build.
avoid_unnecessary_containers
Avoids using Container when it's not doing anything.
π§ Replace it with Padding, SizedBox, DecoratedBox, etc.
π‘ Reduces widget tree complexity.
avoid_print
Avoid using print() in production code.
π§ Use Logger, debugPrint, or proper logging tools.
π‘ Makes log control and maintenance easier.
prefer_single_quotes
Prefers single quotes (') over double quotes (").
π§ Promotes code consistency.
π‘ Follows the standard of most Dart/Flutter packages.
always_declare_return_types
Enforces declaring return types for functions.
π§ Example: String getTitle() { ... }
π‘ Improves readability and prevents potential errors.
unnecessary_const
Avoids using const where it's redundant (like inside another const).
π§ Dart infers it automatically in many cases.
π‘ Keeps your code cleaner and more concise.
no_literal_bool_comparisons
Avoids comparisons like if (isValid == true) or == false.
π§ Instead, use if (isValid) or if (!isValid).
π‘ Makes your code more direct and idiomatic.
use_key_in_widget_constructors
Ensures you add a Key to your custom widgets.
π§ Helps control widget rebuilds in the widget tree.
π‘ Prevents subtle bugs and improves performance.
unnecessary_lambdas
Avoids using lambdas when you can pass the function directly.
π§ Instead of onPressed: () => doSomething(), use onPressed: doSomething.
π‘ Results in cleaner and more readable code.
unnecessary_getters_setters
Avoids get and set methods that do nothing but return or assign a variable.
π§ Access the field directly when there's no added logic.
π‘ Simplifies code and avoids unnecessary abstractions.
By enabling these lints, you're not just following best practicesβ-βyou're also making your Flutter codebase more robust, scalable, and professional. Happy coding! π
