errors method

List<String>? errors()

Check if any error entries are present in the stack. Returns a list of error strings if any are found, null if none are found.

Implementation

List<String>? errors() {
  if (_stack.isEmpty) {
    return null;
  }
  return _stack.toList
      .where((e) => e.hint == dataHints.error)
      .map((e) => e.data)
      .toList()
      .cast<String>();
}
