allValues property

@override Stream<bool> allValues

Return a stream of all input values regardless whether the new value is different than the previous value.

Implementation

@override
Stream<bool> get allValues {
  if (_valuesController != null) {
    throw GpioException(
        'cancel existing values or allValues stream'
        ' before calling values or allValues again',
        physicalPin);
  }
  _valuesController = StreamController(onListen: () {
    gpio._rspHandler.pollingMap[bcmGpioPin] = this;
    gpio._sendPort.send(comm.startPollingCmd(bcmGpioPin));
  }, onCancel: () {
    gpio._sendPort.send(comm.stopPollingCmd(bcmGpioPin));
    gpio._rspHandler.pollingMap.remove(bcmGpioPin);
    _valuesController = null;
  });
  return _valuesController!.stream;
}
