flutter/dart : How to close camera after continuous few barcodes scanning - flutter

Question

I have used flutter_barcode_scanner: ^2.0.0 package to scan barcodes it work fine but I scan continuously and after few barcodes i want to close the camera and return back to screen now I am stock so how the camera is closed after scanning few barcodes.
the following is a scenario I wont to implement
scanBarcode() {
FlutterBarcodeScanner.getBarcodeStreamReceiver(
"#ff6666",
"Cancel",
false,
ScanMode.DEFAULT,
)!
.listen(
(barcode) {
setState(() {
list.add(barcode);
});
if (list.length == 10) {
// I want to close camera here and show page again?
}
},
);
}

I had the same issue. The workaround is to loop on single scan. So as a result you can still continue to use flutter_barcode_scanner package :).
In my case i don't need to call setState or something like to update the UI but you can do it if you need.
Future<String?> _scanBarcodeNormal() async {
String? barcodeScanRes;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
barcodeScanRes = await FlutterBarcodeScanner.scanBarcode('#ff6666', 'Cancel', true, ScanMode.BARCODE);
} on PlatformException {
barcodeScanRes = 'Failed to get platform version.';
}
return barcodeScanRes;
}
void _scanBarCodeListAndFetchData() async{
String? barcode = await _scanBarcodeNormal();
final List<String> barcodeList = [];
// continue scanning
while(barcode != null){
if(barcode == "-1"){ // cancel button -> -1
barcode = null;
}
// add the barcode
else {
// avoid duplicates
if(!barcodeList.contains(barcode)){
barcodeList.add(barcode);
}
// you can also call setState(() {....} here
if (barcodeList.length == 10) {
barcode = null; // out !
}
else{ // next scan
barcode = await _scanBarcodeNormal();
}
}
}
if(barcodeList.isEmpty) {
UiUtils.showToast(message: "No barcode scanned, abort", toastLength: Toast.LENGTH_SHORT);
}
else{
UiUtils.showToast(message: "${barcodeList.length} barcodes scanned", toastLength: Toast.LENGTH_SHORT);
// your work
}
}
