Warns when a Column, Row, Flex, Wrap, SliverList, SliverMainAxisGroup or SliverCrossAxisGroup widget has only one child.

A Column or Row widget with only one child is usually a sign of a mistake. If you want to center the child widget, prefer the Center widget instead.

Example​

❌ Bad:

Widget build(BuildContext context) {
  // LINT: Avoid 'Row' widgets with only one child. Try using a dedicated widget instead.
  return Row(children: [
    SomeWidget(),
  ]);
}

✅ Good:

Widget build(BuildContext context) {
  return Row(children: [
    SomeWidget(),
    SomeWidget(),
  ]);
}

Widget build(BuildContext context) {
  return Center(child: SomeWidget());
}
