Error Layout when scrolling page

[rendramhardika]

Hai, Thanks for developed this widget. I've got some issues.
I trying to create many forms with that flying action button. When there are many forms, i've got some error with error message like this.

[krishnashetty0]

I am getting this error.
It happens when I add more that one forms and try to scroll up and down. Any hints?

[krishnashetty0]

Opened this SO https://stackoverflow.com/questions/62035839/listview-crashes-list-of-statefulwidgets

[Basyir91]

Has anyone found any solutions?

I just want to share my solution: In form.dart:

line 8: delete final state = _UserFormState();

line 13: replace
_UserFormState createState() => _UserFormState();
bool isValid() => _UserFormState().validate();

this doesnt work. validate functions return empty!.

inside the multiform page using the ListView inside the SingleChildScroolView

it was working for me

SingleChildScrollView(
child: ListView.builder(
physics: NeverScrollableScrollPhysics(),
shrinkWrap: true,
scrollDirection: Axis.vertical,
addAutomaticKeepAlives: true,
itemCount: products.length,
itemBuilder: (_, i) => products[i],
),
),
