use_decorated_box

Description

Use DecoratedBox over Container when only Decoration is specified.

Fixes #3060

Kind

Style advice.

Bad Example

Widget buildArea() {
  return Container(
    decoration: const BoxDecoration(
      color: Colors.blue,
      borderRadius: BorderRadius.all(
        Radius.circular(5),
      ),
    ),
    child: const Text('...'),
  );
}

Good Example

Widget buildArea() {
  return const DecoratedBox(
    decoration: BoxDecoration(
      color: Colors.blue,
      borderRadius: BorderRadius.all(
        Radius.circular(5),
      ),
    ),
    child: Text('...'),
  );
}

Other than the one missing test case, this looks good.
