readLineSync method

@override String? readLineSync()

Reads a line synchronously from input.

Used for text input prompts where the user types a full line. Requires lineMode to be enabled for proper behavior. Returns null if end-of-input is reached.

Implementation

@override
String? readLineSync() {
  if (_lineQueue.isEmpty) {
    return null;
  }
  return _lineQueue.removeAt(0);
}
