Implementation

@override
Future<List<String>> getSuggestions(
  final String input,

  _inputs.add(input);
  final List<String>? cached = _cache[input];
  if (cached != null) {
    return cached;
  }
  await waitForTestPurpose();
  _cache[input] = await autocompleter.getSuggestions(input);
  // meanwhile there might have been some calls to this method, adding inputs.
  for (final String latestInput in _inputs.reversed) {
    final List<String>? cached = _cache[latestInput];
    if (cached != null) {
      return cached;
    }
  }
  // not supposed to happen, as we should have downloaded for "input".
  return <String>[];
}
