NestedPageViewNotifier class
A widget to enable or notify scrolling of PageView which contains another PageView or TabBarView inside.
Note that a TabBarView can also be treated as a PageView because of its implementation,
you can use BuildContext.findAncestorWidgetOfExactType or BuildContext.visitDescendantElementsBFS
to get its inner PageController.
Example:
PageView(
controller: _controller,
children: [
// other pages...
Column(
children: [
TabBar(...),
Expanded(
child: NestedPageViewScrollable(
parentController: _controller,
child: TabBarView(...),
),
),
],
),
// other pages...
],
);
