added in: 1.9.0

warning

Warns when a break, continue, return or throw are used unconditionally in a for loop.

Example

❌ Bad:

void main() {
  final list = <int>[];

  for (final item in list) {
    continue; // LINT
  }

  for (final item in list) {
    break; // LINT
  }

  for (final item in list) {
    return; // LINT
  }

  for (final item in list) {
    throw ''; // LINT
  }
}

✅ Good:

void main() {
  final list = <int>[];

  for (final item in list) {
    if (someCondition) {
      continue;
    }
  }

  for (final item in list) {
    if (someCondition) {
      break;
    }
  }

  for (final item in list) {
    if (someCondition) {
      return;
    }
  }

  for (final item in list) {
    if (someCondition) {
      throw '';
    }
  }
}
