Also, to better address the issue, would be helpful if you could post a minimal code sample to reproduce the problem
Thank you

Hi @YashMobileFirst
Just tested the issue and you're missing firebase web configuration in your index.html file

  <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>

  <script>
    // TODO: Replace the following with your app's Firebase project configuration.
    // See: https://support.google.com/firebase/answer/7015592
    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: "G-..."
    };
    // Initialize Firebase
    firebase.initializeApp(firebaseConfig);
  </script>

  <script src="main.dart.js" type="application/javascript"></script>

Please follow this guide

Thank you

[YashMobileFirst]

In my project i add firebase web configuration in my index.html but still same result :(

[TahaTesser]

I just tested the issue and adding the proper configuration solved the issue
Can you post your index.html by replacing your credentials
Thank you
