Refresh widget or page in Flutter without ListView et al
You can simply wrap your content in a SingleChildScrollView
, which will allow you to use a RefreshIndicator
. In order to make the pull down to refresh interaction work, you will have to use AlwaysScrollableScrollPhysics
as your content will most likely not cover more space than available without a scroll view:
RefreshIndicator(
onRefresh: () async {
// Handle refresh.
},
child: SingleChildScrollView(
physics: const AlwaysScrollableScrollPhysics(),
child: /* your content */,
),
);
You can just use GestureDetector
, I have created a sample for you, but it's not perfect, you can customize it to your own needs, it just detects when you swipe from the top.
class Test extends StatefulWidget {
@override
_TestState createState() => _TestState();
}
class _TestState extends State<Test> {
var refresh=false;
void refreshData(){
if(!refresh){
refresh=true;
print("Refreshing");
Future.delayed(Duration(seconds: 4),(){
refresh =false;
print("Refreshed");
});
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
appBar: AppBar(
title: Text("Test"),
centerTitle: true,
),
body: GestureDetector(
child: Container(
color: Colors.yellow,
height: double.infinity,
width: double.infinity,
child: Center(child: Text('TURN LIGHTS ON')),
),
onVerticalDragUpdate: (DragUpdateDetails details){
print("direction ${details.globalPosition.direction}");
print("distance ${details.globalPosition.distance}");
print("dy ${details.globalPosition.dy}");
if(details.globalPosition.direction < 1 && (details.globalPosition.dy >200 && details.globalPosition.dy < 250)){
refreshData();
}
},
));
}
}
