Installation

Flutter Firebase Configuration Guide

This guide will walk you through the process of setting up a Flutter application to work with Firebase.

Pre-requisites

• Flutter SDK Installed
• Firebase account
• An Android or iOS device or emulator for testing

Firebase Console Configuration

Creating a Firebase project

• Go to the Firebase console: https://console.firebase.google.com/
• Click on "Add Project".
• Enter a project name and follow the instructions to create the project(you might have to create a new package name incase of a conflict. Follow these instructions to update project package name).

Adding Firebase to your Flutter app

For Android:

• In the Firebase console, click on the Android icon to add an Android app to the Firebase project.
• Enter the package name of your Flutter app (you can find this in the AndroidManifest.xml file in your Android project).
• Download the google-services.json file and place it in the android/app directory of your Flutter project.

For iOS:

• In the Firebase console, click on the iOS icon to add an iOS app to the Firebase project.
• Enter the bundle ID of your Flutter app (you can find this in the Info.plist file in your iOS project).
• Download the GoogleService-Info.plist file and place it in the ios/Runner directory of your Flutter project.

Firebase Authentication Configuration

• In the Firebase console, select your project.
• From the sidebar, select "Authentication".
• Under the "Sign-in method" tab, you'll see a list of sign-in providers.
• Locate "Email/Password" in this list and click on the pencil/edit icon.
• Switch the "Enable" toggle to enable Email/Password sign-in.
• Click "Save".

Once this is done, your Flutter application will be able to use Firebase's Email/Password authentication system.

Firebase Rules

Firebase rules can be set for Firestore and Firebase Storage to control read and write permissions.

For Firestore:

rules_version = '2';

service cloud.firestore {
  match /databases/{database}/documents {
    match /pollingImages/{document=**} {
      // Any user can read documents
      allow read: if true;
      // No one can write documents
      allow write: if false;
    }
    match /pollingImages/{userId}/{document=**} {
      // Any user can read documents
      allow read: if true;
      // Authenticated user can write their own documents
      allow write: if request.auth != null && request.auth.uid == userId;
    }
    // Match the votes subcollection
    match /pollingImages/{userId}/uploads/{upload}/votes/{vote} {
      // Only authenticated users can read or write votes
      allow read, write: if request.auth != null;
    }
  }
}

For Firebase Storage:

rules_version = '2';

service firebase.storage {
  match /b/{bucket}/o {
    match /userImages/{userId}/{allPaths=**} {
      allow read: if true;
      allow write: if request.auth != null && request.auth.uid == userId;
    }
  }
}

Note: These rules are not production ready
