While developing a flutter web app, I was using the dev firebase project. Now, when the development is finished it is required to use the production firebase project for production. How can this be done other then simply swapping the firebase dev configuration from index.html with the prod firebase config before building the app.

I tried this tutorial Dynamic HTML elements but I couldn't adapt it to my solution.
I thought that the configuration could be added as a child but an error was thrown:
Expected a value of type 'Element', but got one of type 'FirebaseOptions'
