Custom Widget Callback Param Not Able To Be Used in Widget Itself (only in Action Flow Editor)

[sgardoll]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

A custom widget with an action callback that includes a string parameter cannot use that string parameter as an input parameter within the widget itself. You can only use it within the Action Flow Editor (to display a snack bar for example).

Expected Behavior

I would have expected to be able to use the string to update the widget itself.

Steps to Reproduce

1. Create a custom widget that accepts file drags.
2. Implement a callback that returns the status as a string.
3. Attempt to display the current status string within the widget.
4. Observe that the status is displayed as a question mark instead of the actual string

Reproducible from Blank

• The steps to reproduce above start from a blank project.
