Advanced Configurations

MatrixScan Pick is optimized by default for efficiency, accuracy, and responsiveness. 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
  }
}
