Flutter iOS: taps on the status bar can't scroll to top
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
CustomScrollView used in home page layout
If you want to pull up and load more, you must define a ScrollController and pass it to CustomScrollView.
My code
ScrollController _scrollController = new ScrollController();
@override
void initState() {
super.initState();
_scrollController.addListener(() {
if (_scrollController.position.pixels >=
_scrollController.position.maxScrollExtent) {
_loadMoreData();
}
});
}
@override
void dispose() {
super.dispose();
_scrollController.dispose();
}
new CustomScrollView(
controller: _scrollController,
slivers: <Widget>[....],
)
However, if this is done, when there is a lot of data loaded, tap the status bar at the top will not scroll to the top!
If you remove the controller in CustomScrollView, or change to PrimaryScrollController.of(context)
new CustomScrollView(
controller: PrimaryScrollController.of(context),
)
this is OK!
why ???
