Your Firebase setup is working perfectly, but it’s missing the “add item to Firebase list” feature found in the native component; everything else is great. I’m willing to pay if you can fix this. I want an extension that behaves as close as possible to the App Inventor one, but without relying on the platform’s built-in version, as that causes a lot of bugs when I transfer the project to another platform.
