There are 3 ways you can use custom code for business logic:

- Custom Functions: https://www.youtube.com/watch?v=CbNtmue0ZZo

- Custom Widgets: https://community.flutterflow.io/c/whats-new-in-flutterflow/...

- Custom Actions: https://community.flutterflow.io/c/whats-new-in-flutterflow/...

The reason there are 3 different kinds of custom code is so that it can easily integrate with the visual builder ... for instance a "Custom Action" function will show up when you add an action on a Button Tap, or TextField submit. A "Custom Widget" can be dragged in and passed parameters, and a "Custom Function" can be used to set values. Would love any feedback
