Advanced Configurations

MatrixScan Pick is optimized by default for efficiency, accuracy, and a seamless user experience. However, there are multiple advanced settings available to further customize MatrixScan Pick to best fit your needs.

BarcodePick Listener

You may want more fine-grained knowledge over the different events happening during the life of the BarcodePick mode, such as when the search starts, pauses, and stops.

To do this, you can directly register a BarcodePickListener on the mode itself, keeping in mind that these listeners are called from a background thread.

barcodePickView.addListener(myListener);

class BarcodePickViewListenerImpl implements BarcodePickViewListener {
  @override
  void didStartScanning(BarcodePickView view) {
    // The view started scanning
  }

  @override
  void didFreezeScanning(BarcodePickView view) {
    // The view was frozen
  }

  @override
  void didPauseScanning(BarcodePickView view) {
    // The view was paused
  }

  @override
  void didStopScanning(BarcodePickView view) {
    // The view stopped scanning
  }
}
