Flutter:Scrolling To Bottom Automatically when the screen opens

Question

I'm using onpressed() to scroll down to bottom of the List view, but i want to achieve that without Pressing the botton,

It must autoscroll for every screen opening. I tried to put it inside initState() its not working but if i press the button it wokrks

How to make it autoScroll?

Working code:

 floatingActionButton: new FloatingActionButton(child: 
 Icon(Icons.arrow_downward),onPressed:_hola,)



_hola(){
  print("inti state started successfully");
controller1.animateTo(
controller1.position.maxScrollExtent,
  duration: const Duration(milliseconds: 10),
   curve: Curves.easeOut,);
}

Non Working Code: //This code prints successfully,but not really calling the function

class HomeState extends State<MyNewMessages> {
  @override
  void initState() 
{
 super.initState();
  print("hola is scrolling");
  _hola;
}
);
}

Before Pressing Floating Button After Pressing Floating Button

Solution

When building your ListView or adding an item (not sure how you're doing it), use SchedulerBinding.instance.addPostFrameCallback to change the scroll position on the next frame.

SchedulerBinding.instance.addPostFrameCallback((_) {
  controller1.animateTo(
    controller1.position.maxScrollExtent,
    duration: const Duration(milliseconds: 10),
    curve: Curves.easeOut,);
  });
}
