此规则提供 快速修复

详情

#

DO use ColoredBox when Container has only a Color.

A Container is a heavier Widget than a ColoredBox, and as bonus, ColoredBox has a const constructor.

BAD:

dart
Widget buildArea() {
  return Container(
    color: Colors.blue,
    child: const Text('hello'),
  );
}

GOOD:

dart
Widget buildArea() {
  return const ColoredBox(
    color: Colors.blue,
    child: Text('hello'),
  );
}
