Info	✅	❌

Details

PREFER using Border.fromBorderSide instead of Border.all.

Using Border.fromBorderSide is more efficient than Border.all because of possible const constructor usage.

Bad

DecoratedBox(
  decoration: BoxDecoration(
    border: Border.all(
      width: 1,
      style: BorderStyle.solid,
    ),
  ),
)

Good

const DecoratedBox(
  decoration: BoxDecoration(
    border: Border.fromBorderSide(
      BorderSide(
        width: 1,
        style: BorderStyle.solid,
      ),
    ),
  ),
)
