avoid-late-final-reassignment

added in: 1.23.0
warning
Pro+

Warns when a late final variable is assigned multiple times in the same block.

Assigning to a late final variables multiple times will throw at runtime and should be avoided.

Example​

❌ Bad:

class _TestState {
  late final String _title;

  void initState() {
    _title = 'title';
    _title = 'another'; // LINT: This late final field is already assigned. Try removing the 'final' modifier or don't reassign the value.
  }
}

✅ Good:

class _TestState {
  late final String _title;

  void initState() {
    _title = 'title';
  }
}
