Flutterfire: [firebase_auth] AndroidX Dependency not found while building release and debug apk

[kroikie]

To my understanding, the dependency requested by firebase_auth (androidx.legacy:legacy-support-v4:26.0.0) doesn't exist; I can only find v1.0.0 on maven.

Edit: Also throws a similar error on flutter build apk --debug

Steps to Reproduce

1. Migrate to AndroidX
2. Include firebase_auth in pubspec.yaml
3. run flutter build apk

For me the issue with this error, and why it is so difficult to find a solution for it is that it is wrong. It took me weeks to resolve this issue because the error has absolutely 0 to do with firebase being incompatible with androidx and everything to do with my key file (your .jks file). For me, the file path was incorrect, and correcting this made everything work again like magic.

It is likely that if you are tearing your hair out over this issue, that this is not even an issue. Have a look at your key store file and make sure everything is correct with it. If the app runs perfectly fine, but will not build, there are only two files involved that are different. Your google-services.json and your keystore file.

Absolutely terrible error reporting.
