Losing widget state when switching pages in a Flutter PageView : <p>I have a series of stateful widgets in a PageView managed by a PageController. I am using <code>pageController.jumpToPage(index)</code> to switch pages. When switching pages all state appears to be lost in the widget, as if it was recreated from scratch. I have tried using <code>keepPage: true</code> in the PageController but that doesn't seem to have any effect. Is this the intended behavior of a PageView or am I doing something wrong? Any suggestions appreciated, thanks!</p>
