Flutter existing project to WebApp + Firebase (Firestore + Hosting)

I have an existing Flutter app (runs correctly on Android/IOS) using Firestore.

GOAL:

  1. I'd like to first have it support web
  2. I'd like to host it on Firebase hosting

Results so far:

  1. When running in local, blank page
  2. When deploying to firebase, doesn't even seem to run index.html

What I tried

  1. According to this tutorial :

    a) Added a Web App on my firebase project

    b) npm install -g firebase-tools

    c) firebase login

    d) firebase init

    ==> I select Firestore and Hosting

    ==> Use existing project, select my project

    ==> use all defaut setup (except build/web folder for public directory)

    e) flutter channel dev flutter upgrade flutter config --enable-web

    f) flutter create .

    g) flutter build web

    h) I then copy all the content from build/web to /web folder, add the CDN from firebase at the bottom of the body, then call Firebase JS SDKs the following way :

ERRORS

I get this error when running locally on chrome: 

(index):53 Uncaught ReferenceError: firebase is not defined

As for using firebase deploy, the page says I successfully set up hosting but does not show index.html

depends on how you have set up your firebase apis.from flutter fire here is how you should set it up. In your app directory, edit web/index.html to add the following: ` 

<body>
    <script src="https://www.gstatic.com/firebasejs/7.5.0/firebase-app.js"></script>
    <script src="https://www.gstatic.com/firebasejs/7.5.0/firebase-firestore.js"></script>
     <!-- ADD THIS BEFORE YOUR main.dart.js SCRIPT -->


var firebaseConfig = {
  apiKey: "",
  authDomain: "[YOUR_PROJECT].firebaseapp.com",
  databaseURL: "https://[YOUR_PROJECT].firebaseio.com",
  projectId: "[YOUR_PROJECT]",
  storageBucket: "[YOUR_PROJECT].appspot.com",
  messagingSenderId: "",
  appId: "1:...:web:",
  measurementId: ""
};
// Initialize Firebase
firebase.initializeApp(firebaseConfig);

`
