我想打开Drawer以编程方式而不是通过滑动它，如何禁用该滑动功能（抽屉的触摸功能）
空安全代码
-
Using GlobalKey:
final GlobalKey<ScaffoldState> _key = GlobalKey(); // Create a key
@override
Widget build(BuildContext context) {
return Scaffold(
key: _key, // Assign the key to Scaffold.
drawer: Drawer(),
floatingActionButton: FloatingActionButton(
onPressed: () => _key.currentState!.openDrawer(), // <-- Opens drawer
),
);
}
-
Using Builder:
@override
Widget build(BuildContext context) {
return Scaffold(
drawer: Drawer(),
floatingActionButton: Builder(builder: (context) {
return FloatingActionButton(
onPressed: () => Scaffold.of(context).openDrawer(), // <-- Opens drawer.
);
}),
);
}
如果您想禁止打开Drawer使用拖动手势，您可以设置
Scaffold(
drawerEnableOpenDragGesture: false
// above code ...
)
