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 BarcodePickViewListener on the view itself, keeping in mind that these listeners are called from a background thread.

const viewListener = {
	didStartScanning(view) {
		// The view started scanning
	},

	didFreezeScanning(view) {
		// The view was frozen
	},

	didPauseScanning(view) {
		// The view was paused
	},

	didStopScanning(view) {
		// The view stopped scanning
	},
};

barcodePickView.addListener(viewListener);
