NoSuchMethodError on cancel()

======== Exception caught by widgets library =======================================================
The following NoSuchMethodError was thrown while finalizing the widget tree:
The method 'cancel' was called on null.
Receiver: null
Tried calling: cancel()

qrcode-dependency throws an error on Android ("Execution failed for task ':qrcode:compileDebugKotlin'.")

Hello,

Thank you for the nice package.

I've been playing around with it, and it was working fine. But after upgrading to new flutter.

The package throws exception when building the project. Execution failed for task ':qrcode:compileDebugKotlin'.

Blank Screen pops up when the Scanner is selected

I'm having a BarCode scanner and a TextFormField.

When presssed on the BarCode scanner it scans perfectly and retreives the BarCode and prints it in the TextFormField.

But when you enter your custom text in the TextFormField and press the BarCode scanner a black screen cones inside the scanner but retreives some odd Barcode value.

TextEditingController someController = TextEditingController();
  String _scannedCode = "";

  scanBarCode() async {
    final data = await Barras.scan(
      context,
      viewfinderHeight: 120,
      viewfinderWidth: 300,
      scrimColor: Color.fromRGBO(128, 0, 0, 0.5),
      borderColor: Colors.red,
      borderRadius: 24,
      borderStrokeWidth: 2,
      buttonColor: Colors.yellow,
      borderFlashDuration: 250,
      cancelButtonText: "Cancel",
      successBeep: false,
    );

    setState(() {
      _scannedCode = data ?? "";
      print(data);
      print(_scannedCode);
    });
  }

I can't even run the app, it's giving me this error with the qrcode library... (even that I want to use just the barcode function)

Feel free to ask me any question so we can solve this issue together (Brasileiro aqui tambem... so escrevi em ingles para see algum extrangeiro tiver alguma ideia de como resolver)

Parabens pelo trabalho incrivel!

Update to null safety!

Really thankful for the package
But to use this with the latest version of flutter with sound null safety, a problem occurs.
As most of the packages are migrated to null safety, this too needs an update.

várias digitalizações

Olá!!

Você pode realizar várias digitalizações sem fechar o scanner?

Obrigado

Tela preta na hora de escanear

Muito boa essa lib.
Funcionou muito bem quase todas as vezes que testei. Mas as vezes a tela de escanear fica preta.
Mesmo com a tela preta ele consegue detectar o código de barras.

Feauture request: validation function

Could you, please, add some validation?
Would be great to pass the function that return true if barcode is valid (scanned item is exists in database, for example) or false if not and scan in infinity loop until this function return true or cancel pressed. Maybe it's reasonable to pass callback for failed scan - developers could show a Toast in that case or play custom sound

Hi! Try to add barras dependency as:

barras:

ref: r0.1.0-nullsafety.2

However, got an error when trying to lunch the app

Android V2 Embedding

The plugins qrcode, torch_compat use a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.
