Unexpected end of input error when configuring with flutterfire

Question

I've been trying to integrate firebase into my flutter project, however I continually get this error when running the flutterfire configure script. The script runs when it is just ios, but not android.

I've blanked out specific identifiers with ////////

    % flutterfire configure
i Found 1 Firebase projects.                                                                                             
✔ Select a Firebase project to configure your Flutter application with · //////////// (////////)                             
✔ Which platforms should your configuration support (use arrow keys & space to select)? · android, ios

Answer 1

Solved by rebuilding the flutter application with a different file name. Don't know the exact problem, but this is my personal solution after trying everything else.

Answer 2

Hellos, I fixed this error by the following steps:

1. Uninstall and Re-install or Update flutterfire via these commands

• dart pub global deactivate flutterfire_cli

• dart pub global activate flutterfire_cli

2. Delete the google_services.json file in the [project_folder]/android/app directory.

3. Re-run the flutterfire configure command

• flutterfire configure
