retry method

Future<void> retry()

Reset and start the whole sequence over (e.g. after an error).

Implementation

Future<void> retry() async {
  _holdTimer?.cancel();
  for (final img in _state.captured) {
    if (await img.file.exists()) await img.file.delete();
  }
  await _releaseCamera();
  if (_disposed) return;
  await initialize();
}
