The rule detects Expanded widgets that contain empty SizedBox/Container and proposes to replace them with the Spacer widget.

❌ Bad:

Column(
    children: [
        Container(),
        const Expanded(child: SizedBox()),
        Container(),
    ]
)

✅ Good:

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