Hello i`m new in flutter. I made a special listView for myself and made a controller for it. In the main page, I have called my own list view and I have a button that I want to execute the following method by pressing it from the Main class and my list view scrolls inside another class. scroll method:
void _animateToIndex(int index) {
_controller.animateTo(
index * 50,
duration: Duration(seconds: 1),
curve: Curves.fastOutSlowIn,
);
}
In fact, I want to execute the method of another class that contains my scrollview from the Main class.
my listView class:
class CustomNumberScroller extends StatefulWidget {
const CustomNumberScroller(
{Key? key, required this.curStep, required this.pageNumberOfMainDart})
: super(key: key);
@override
State<CustomNumberScroller> createState() => _CustomNumberScrollerState();
}
final dataKey = new GlobalKey();
final ScrollController _controller = ScrollController();
void _animateToIndex(int index) {
_controller.animateTo(
index * 50,
duration: Duration(seconds: 1),
curve: Curves.fastOutSlowIn,
);
}
class _CustomNumberScrollerState extends State<CustomNumberScroller> {
@override
Widget build(BuildContext context) {
Size media = MediaQuery.of(context).size;
return ...
}
}
