Firebase Storage Not Working with Flutter on Windows? We’ve Got the Fix!

If you’re struggling to get Firebase Storage to work with your Flutter app on Windows, you’re not alone! Many developers have faced this frustrating issue, but don’t worry, we’re here to guide you through the troubleshooting process and get your app up and running smoothly.

Why is Firebase Storage Not Working?

Before we dive into the solution, let’s understand the possible reasons behind this issue. Firebase Storage is a cloud-based storage service that allows you to store and serve files from your Flutter app. However, on Windows, Firebase Storage might not work due to:

• Incorrect configuration of the Firebase project
• Missing or invalid Google Services configuration file (google-services.json)

<

• Incompatible version of the Firebase SDK
• Insufficient permissions or authentication issues

Step 1: Verify Your Firebase Project Configuration

To ensure that your Firebase project is set up correctly, follow these steps:

1. Go to the Firebase Console (https://console.firebase.google.com/) and select your project.
2. Click on the “General” tab and ensure that the “Config” section is enabled.
3. Download the google-services.json file and add it to your Flutter project’s android/app directory.

// android/app/google-services.json
{
  "project_info": {
    "project_number": "1234567890",
    "firebase_url": "https://example.firebaseio.com",
    "project_id": "example-app"
  },
  "client": [
    {
      "client_info": {
        "mobilesdk_app_id": "1:1234567890:android:1234567890123456",
        "android_client_info": {
          "package_name": "com.example.app"
        }
      },
      "oauth_client": [
        {
          "client_id": "1234567890-abcdefg123456.apps.googleusercontent.com",
          "client_type": 3,
          "android_info": {
            "package_name": "com.example.app",
            "certificate_hash": "abcdefg1234567890"
          }
        }
      ]
    }
  ],
  "configuration_version": "1"
}

Step 2: Install and Configure the Firebase SDK

To use Firebase Storage in your Flutter app, you need to add the Firebase SDK to your project. Follow these steps:

1. Add the following dependencies to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  firebase_core: ^1.10.0
  firebase_storage: ^10.2.9

2. Run the following command in your terminal to get the packages:

flutter pub get

Step 3: Initialize Firebase in Your App

To initialize Firebase in your app, add the following code to your main function:

import 'package:firebase_core/firebase_core.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(MyApp());
}

Step 4: Configure Firebase Storage

To use Firebase Storage, you need to configure it in your app. Add the following code to your main function:

import 'package:firebase_storage/firebase_storage.dart';

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  FirebaseStorage storage = FirebaseStorage.instance;
  storage.ref().child('example.txt').putFile(file);
  runApp(MyApp());
}

Common Issues and Solutions

If you’re still facing issues with Firebase Storage, here are some common problems and their solutions:

Error Message	Solution
firebase_storage plugin is not compatible with the latest version of Flutter	Downgrade the firebase_storage plugin to a compatible version (e.g., 5.2.0)
Missing or invalid google-services.json file	Download the correct google-services.json file from the Firebase Console and add it to your project
Insufficient permissions or authentication issues	Ensure that you have enabled the correct permissions in the Firebase Console and that your app is properly authenticated
