How to use my TensorFlow machine learning model (or any other ML model) inside FF?

I've tried several ways to integrate tensorflow lite model (*.tflite) within my FF app:

1- The following article describes how to upload the model to Firebase ML inside Firebase store and to enable this option inside Firebase options in FF, but I couldn't really find it (attached screenshot), or any documentation about it: https://www.rapidevelopers.com/flutterflow-tutorials/how-to-create-custom-machine-learning-models-in-flutterflow

2- Other ways describe how to integrate it with Flutter, and then, it should be possible to integrate it inside FF as a custom widget,, but it didn't work as well...
