drainForTest method

  1. @visibleForTesting
Future<void> drainForTest()

Runs any pending PTY ingest immediately. For unit/widget tests that do not pump frames (the default schedule uses post-frame callbacks).

Implementation

@visibleForTesting
Future<void> drainForTest() async {
  while (_buf.isNotEmpty || _drainScheduled || _advancing) {
    if (_drainScheduled || _buf.isNotEmpty) {
      await _drain();
    } else {
      await Future<void>.delayed(Duration.zero);
    }
  }
  await _applyPendingScroll();
}
