  # Use with the CupertinoIcons class for iOS style icons.

When I try integrating anything firebase in the application I get a series of compile errors which go away when I remove that code. I suspect I have something misconfigured or there is a version conflict somewhere.

I am running Android Studio 3.1

Answer 1

For a flutter project. First, delete your Firebase app on project settings then click on remove this app, after that go to the route of your project and paste these commands.

Command 1: dart pub global activate flutterfire_cli.

Command 2: flutterfire configure --project=YOUR PROJECT NAME

Answer 2

I also ran into this issue and resolved it by updating everything:

• Android studio 3.1 -> 3.2
• All the SDK Tools that I already installed (Tools > SDK Manager > SDK Tools)
• The Flutter and Dart plugins (Preferences > Plugins)

I also tried Justin's answer of uninstalling the Firebase plugins, restarting, then reinstalling.

After everything, restart Android Studio and let the IDE finish all of its indexing and other tasks, then open Firebase assistant (Tools > Firebase)

Answer 3

I had the same problem. I went to Settings > Plugins and then removed all 3 firebase plugins. Restarted. Back to Plugins, add all 3 firebase plugins. Restart. Then it worked fine!
