preset: recommended

Warns when a collection literal in spread (...[]) has no elements.

Example

❌ Bad:

void fn(bool flag) {
  final another = [
    ...<String>[], // LINT
    if (flag) ...<String>[], // LINT
  ];
}

✅ Good:

void fn(bool flag) {
  final another = [
    ...<String>['some', 'elements'],
  ];
}
