Flutter Flow - Use actions provided by Parent component in Child Component

I am using Flutter flow to build an app that has a List view of buttons which when clicked changes the background of the list view. So, for example, my list has 2 items Nature and Space, when Nature is clicked it should change the background of the List view (NOT button) to nature's image and similarly for space.

How I am trying to achieve this:
I have made an item as a reusable component that takes an action as a parameter.
Example:

In the parent list view, one state variable is being used to define the background image, and as the definition of the child's action parameter (in this example: updateMenuImage), this variable is updated based on the action's parameter.

Now, the problem is in the Action Editor of the child widget, I am not getting any option to select this action (which is passed as a component parameter to it).

I would like to know, how we can achieve this or if it is not possible with the current release.

You need to use an Execute Callback action.
