Flutter App Feature Development & Deployment

Job ID: 38266288

Budget: $10 – $30 USD

I'm developing a Flutter application and require assistance with developing and deploying.
The project can be run with `flutter run` and it displays correctly.
`flutter build web --web-renderer html --release` returns: `√ Built build\web`
and `firebase deploy --only hosting` returns `+ Deploy complete!`
But when going to the page hosted in firebase I get `Uncaught (in promise) null`

Anyone who can correct the code in order to deploy appropriately please help. There will be more features to develop later.

- Experienced in developing and deploying Flutter apps on Android, iOS, and Web
- Knowledge in Firebase deployment
- Ability to debug error messages and resolve deployment problems
- Understanding of adding in-app features such as user authentication, push notifications, and in-app purchases.
