It usually happens because of improper placement of firebase JS SDK scripts. You have to setup the SDK before the script tag with main.dart.js.

Update the <base href="/"> tag in web/index.html to the path where your app is hosted. For example, to host your Flutter app at myapp.dev/flutter_app, change this tag to <base href="/flutter_app/">.

or you can even delete this line and it will work.
