Great tutorial. Thanks for that.

I am not sure if it is relevant to this topic or not but I have a problem with Form validation when they are out of the screen in the ListView. ListView disposes those items that are out of the screen -as you explained- and validation fails.

This looks odd.
This shouldnโ€™t happen if you use a basic ListView because all items are rendered once unlike ListView.builder().

You can also checkout this episode from the Flutter UI Widgets course.
It covers how to use forms in Flutter and i used a ListView there too.
Maybe youโ€™re missing a form key or something.
