Eu tentei criar um scanner de QR Code no meu aplicativo usando Flutter.Eu adiciono o dependencia barcode_scan: ^ 0.0.4 no pubspec.yaml e a permissão para a câmera no manifesto, mas toda vez que o mesmo erro foi mostrado que nenhuma implementação encontrada para o método scan, eu não consegui encontrar a solução.
Quando eu adiciono no meu manifesto me dá erro de pacote não resolvido.

FlutterApplication and put your custom class here. -->
