PageView PageController.jumpPage with StreamBuilder in flutter

Question

Here's the code.

Widget build(BuildContext context) {
    return StreamBuilder<List<Widget>>(
        stream: _getMealsViewWidgets(weekNum),
        builder: (BuildContext context, AsyncSnapshot<List<Widget>> snapshot) {
          if (snapshot.connectionState == ConnectionState.active) {
            return Center(child: CircularProgressIndicator());
          }

          if (snapshot.connectionState == ConnectionState.waiting) {
            return Center(child: CircularProgressIndicator());
          }

          if (snapshot.error != null) {
            return Center(child: Text('Error occurred.'));
          }

          if (snapshot.connectionState == ConnectionState.done) {
            return PageView(children: snapshot.data, controller: _pageController);
          }
          return Center(child: CircularProgressIndicator());
        });
  }

The PageView has fix 7 pages. I'd like to jump after a refresh to a specific page. The problem is because the PageView is a return of a StreamBuilder I can't call the pagecontroller.jumpPage method after the refresh. How can I jump to a specific page after return?

Have you tried using

WidgetsBinding.instance.addPostFrameCallback((_) {
  // executes after build
})

?
