Bloc: MissingPluginException(No implementation found for method init on channel plugins.flutter.io/google_sign_in

[Mo-rema07]

I followed the tutorial on https://bloclibrary.dev/#/flutterfirebaselogintutorial. The email and password login and register features work perfectly, however when I press the sign_in_with_google button I get

MissingPluginException(No implementation found for method init on channel plugins.flutter.io/google_sign_in

How do I solve this?
I ran flutter run -v and got the following file
error.log

Hi @Mo-rema07 👋

It looks like your plugin is not injected in the platform side. Make sure you flutter clean, quit your IDE and re-run your app. Just a simple hot reload/restart won't do it.

Thanks as always @RollyPeres for taking the time to answer!

@Mo-rema07 closing this for now but feel free to comment with additional questions and I’m happy to continue the conversation 👍

@RollyPeres I ran flutter clean, closed my IDE, restarted the app, and still got the same error.

Can you share a sample app ?

It seems your plugin was not registered as already mentioned.
If you compare https://github.com/Mo-rema07/shades/blob/master/android/app/src/main/kotlin/org/teal/shades/MainActivity.kt

to the official example: https://github.com/flutter/plugins/blob/master/packages/google_sign_in/google_sign_in/example/android/app/src/main/java/io/flutter/plugins/googlesigninexample/EmbeddingV1Activity.java

although the default native language is different, you'll still notice you're missing the plugin registration.

Try removing the package and re-adding it, close the IDE and start your project again.
Make sure the plugin gets registered.
