Hi @Hamid811394
As mentioned in https://github.com/firebase/firebase-android-sdk/issues/1143#issuecomment-576766359

protobuf-java and protobuf-lite are incompatible packages. They both include classes in the com.google.protobuf package. protobuf-java is typically used in packages intended for desktop and server-side use (i.e. regular Java), while protobuf-lite is frequently used in packages that target Android. Firebase packages depend upon protobuf-lite.

It seems you are using the discontinued barcode_scan package, which is causing the protobuf conflict. Could you please consider using a different package? If you wish to keep using the same one you would need to try something like https://stackoverflow.com/a/59610213

Does this solve the issue for you?

[Hamid811394]

Hi @markusaksli-nc thanks for your reply . I consider to use another barcode package .

[markusaksli-nc]

Alright, I'm going to close this issue for now then.
