Description
Steps to Reproduce
- Run this code :
import'package:flutter/material.dart';voidmain() {runApp(MyApp());}classMyAppextendsStatelessWidget {finalPageController _pageController=PageController();@overrideWidgetbuild(BuildContext context) {returnMaterialApp( home:Scaffold( body:PageView( controller: _pageController, children: [Container(color:Colors.red),Container(color:Colors.green),Container(color:Colors.blue), ], ), floatingActionButton:FloatingActionButton.large( child:constIcon(Icons.navigate_next), onPressed: () { _pageController.nextPage( duration:constDuration( milliseconds:250, ), curve:Curves.easeInOutBack); }, ), ), ); }}
- On android, scroll to page 2 using FAB and come back to page 1 and use FAB to scroll to next page.
- On linux and web, press the FAB to scroll to next page.
Expected results:
PageView should scroll to the next page on clicking the FAB.
Actual results:
On Android: The page scrolls at first. but after coming back to the 1st page, it won't scroll to the next page. From the overscroll glow indicator it seems like it's trying to go in the wrong direction. This happens only on the 1st page.
On Linux and Web: The 1st page wont scroll using FAB.
This only happens on using the PageController.animateTo() and nextPage() method, jump() seems to work fine.
