[iOS] - App is crashing while trying to use barcode scanner

[ghost]

Bug description
I have implemented the plugin in version 0.7.1 to use the barcode scanner. In Android this works without problems. When I start the app, I get the following error on iOS (I implemented the requirements in readme):

8.6.0 - [Firebase/Core][I-COR000003] The default Firebase app has not yet been configured. Add FirebaseApp.configure() to your application initialization. This can be done in in the App Delegate's application(:didFinishLaunchingWithOptions:)(or the@mainstruct's initializer in SwiftUI).

I experienced the same issue. Changing ResolutionPreset.veryHigh to ResolutionPreset.medium on the CameraController solved it for me.

[ghost]

I get the error at every ResolutionPreset, even with ResolutionPreset.low or ResolutionPreset.medium.

[natalia-dev]

Same problem here. Changing ResolutionPreset made no difference.

Downgraded to version 0.6.0 and it worked

[ghost]

I retried it with version 0.7.2, but the error is still present. The problem with version 0.6.0 is, that it does not yet include the BarcodeFormat (in BarcodeValue) in the Barcode result.

I too have this issue, should I just configure firebase? That seems like a lot...

[ghost]

I still have the problem. Has anyone found a solution yet? Or is it really necessary to configure Firebase for iOS?

[paj-co]

I have just opened new issue with the same problem. Didn't noticed that the problem was already issued and exists for so long.
Is it a sign that this library has been somewhat neglected? 🤔

We released a new version of google_ml_kit in which we have split all the plugins in multiple plugins to avoid removing the models for API you are not using, go to our readme and start using the new plugin you need.

Start using:
