Suggests using the Spacer widget instead of the Expanded widget containing empty SizedBox/Container widget.

Example

❌ Bad:

Column(
  children: [
    Container(),
    // LINT: Prefer replacing this widget with the 'Spacer' widget.
    const Expanded(child: SizedBox()),
    Container(),
  ],
);

✅ Good:

Column(
  children: [
    Container(),
    const Spacer(),
    Container(),
  ],
);
