No scrollbar in (infinite) list widget. #41434

Description

@davidcavazos

While following and completing the instructions on Write your first app, the resulting application does have an infinite scrolling list, but there is no (updating) scroll bar to show the "progress" of the list.

I would expect a scroll bar allowing to navigate from the first element to the "last element in memory", and updating as new content keeps loading.

    Hello @davidcavazos !

    Thank you for posting an issue.
    Can you please also provide an output of the flutter doctor -v command?

    Thank you.

    Of course! I'm using web so Android and Xcode shouldn't affect this, but I've already run flutter doctor --android-licenses and got an error, and tried running pod setup but hasn't changed the status.

    Update: I have fixed both issues and my flutter doctor now comes up clean: Android license and pod setup

    Any updates on this?

    The infinity scrollbar drag still breaks the code.

    I have a proposal for this, but it needs some refinement. I am currently working on 2D scrolling issues as a higher priority, but once resolved I should be able to return to this. I have updated the priority label.
