[database] apply plugin: 'com.google.gms.google-services' not working #1299

Closed CoreyCole closed 5 years ago

Describe the bug I'm unable to connect to my firebase realtime database and I'm unable to make a connection to the crashlytics server. I've followed the instructions for database here and crashlytics here.

Someone has a similar issue from 2 months ago on stack overflow with no posted solution. Another similar issue was solved by flutter clean, but unfortunately this didn't solve for me. Looks like there is also an open issue in this repo that may be related here.

It looks like google-services plugin cannot find my google-services.json file even though I've re-downloaded and placed it in the android/app directory multiple times now between flutter clean builds. I've simplified the issue just to the realtime database connection and removed all the crashlyics code/config for the time being and I'm still getting the same primary error message

java.lang.IllegalStateException: FirebaseApp with name DEFAULT doesn't exist. Available app names: [DEFAULT]

To Reproduce

main.dart

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_crashlytics/flutter_crashlytics.dart';
import 'src/app.dart';

void main() async {
    bool isInDebugMode = true;

    FlutterError.onError = (FlutterErrorDetails details) {
        if (isInDebugMode) {
            // In development mode simply print to console.
            FlutterError.dumpErrorToConsole(details);
        } else {
            // In production mode report to the application zone to report to
            // Crashlytics.
            Zone.current.handleUncaughtError(details.exception, details.stack);
        }
    };

    await FlutterCrashlytics().initialize();

    runZoned<Future<Null>>(() async {
        runApp(App());
    }, onError: (error, stackTrace) async {
        print('FLUTTER CRASH');
        // Whenever an error occurs, call the `reportCrash` function. This will send
        // Dart errors to our dev console or Crashlytics depending on the environment.
        await FlutterCrashlytics().reportCrash(error, stackTrace, forceCrash: false);
    });
}

            )
        );
    }

What I've tried

CoreyCole commented 5 years ago

Since I'm no longer interested in crashlytics until I can get the database working, I'll change the tag in the title.

CoreyCole commented 5 years ago

I've made a minimum reproduction case here: https://github.com/CoreyCole/test_firebase_app

And asked on stack overflow here: https://stackoverflow.com/questions/58528230/flutter-firebase-realtime-database-firebaseapp-with-name-default-doesnt-exist

CoreyCole commented 5 years ago

I solved the issue. It boiled down to a documentation/error message problem:

// bad
final FirebaseApp app = FirebaseApp(name: 'DEFAULT');

// good
final FirebaseApp app = FirebaseApp(name: '[DEFAULT]');

Unfortunately, in the example app for database, we connect to a db named db2. So I couldn't see what the correct default syntax looked like.

I've made a documentation PR to show the correct default syntax: https://github.com/FirebaseExtended/flutterfire/pull/1306
