Selected Item in List-- show position

[Andrew Villegas]

Hi Flutter Community,

I posted a question yesterday and just realized I can do a better job at describing my issue, so here is a better description of it!

I have ListView.builder with horizontal scrolling (a custom top navigation bar). As I scroll to the right, the 'selectedIndex' is changing, but the UI inside this widget isn't showing this change in position (please see screenshot attached/ pink container at the top). 

As I swiped right, the 'selected Index' indeed changes, but I'd like to show the position of this change in index as well in my widget. In other words, I'd like the listview to scroll to the right(or left) depending on the selected Index. 

How can I achieve this?

Any guidance would mean a lot.

Thanks,

A.V.

Glad to hear it worked.

To become more experienced with Flutter, learn how to use debugger and release your own app.

Thanks for this, Suzuki. Got it to work!

Also, totally unrelated question... what would you say is the best way to become more experienced with Flutter? Is it by working on real-life projects/following tutorials/ reading the documentation? A mixture of these? Is any of these not the most ideal approach?

I'm really trying to improve as much as I can :) 

Thanks!

Best,

A.V.
