Add Firebase

Step 1: Create a new Firebase project

Go to console.firebase.google.com and create a new Firebase project.

Step 2: Enable Google Sign In for your project

In the Firebase console, go to "Authentication" and enable Google sign in. Click on "Web SDK Configuration" and copy down your Web client ID.

Step 3: Add Client ID to index.html

Uncomment this line in index.html and replace <YOUR WEB CLIENT ID> with the client ID from Step 2:

  <!-- Uncomment and add Firebase client ID here: -->
  <!-- <meta name="google-signin-client_id" content="<YOUR WEB CLIENT ID>"> -->

Step 4: Create a web app

In the Firebase console, under "Project overview", click "Add app", select Web, and replace the contents of web/firebase_init.js.

// web/firebase_init.js
var firebaseConfig = {
    apiKey: "",
    authDomain: "",
    databaseURL: "",
    projectId: "",
    storageBucket: "",
    messagingSenderId: "",
    appId: ""
};

// Initialize Firebase
firebase.initializeApp(firebaseConfig);

Step 4: Create Cloud Firestore

Create a new Cloud Firestore database and add the following rules to disallow users from reading/writing other users' data:

rules_version = '2';

service cloud.firestore {
  match /databases/{database}/documents {
    // Make sure the uid of the requesting user matches name of the user
    // document. The wildcard expression {userId} makes the userId variable
    // available in rules.
    match /users/{userId}/{document=**} {
      allow read, update, delete: if request.auth.uid == userId;
      allow create: if request.auth.uid != null;
    }
  }
}

Step 5: Run the app

Run the app on port 5000:

flutter run -d chrome --web-port=5000

If you see CORS errors in your browser's console, go to the Services section in the Google Cloud console, go to Credentials, and verify that localhost:5000 is whitelisted.

(optional) Step 7: Set up iOS and Android

If you would like to run the app on iOS or Android, make sure you've installed the appropriate configuration files described at firebase.google.com/docs/flutter/setup from step 1, and follow the instructions detailed in the google_sign_in README
