Adding Containers to Page A from Page B Button Press in Flutter Without Using Lists

Question

There is an add button on Page B, onPressed, it should add a new container to add A which can be added using a widget called BuildCourseContainer,

Add Button code:

IconButton(
            onPressed: (){
              
        }, 

Now here is something, I dont want to add containers in page A using list so its not an option, is there any other way?

Answer 1

Just use List or Array. the Button should add item to list when it clicked, then your Page will listen or build item from the List
