如何创建可以在上/下/左/右挥动的卡片?
我看到可以使用 PageView ,但这仅适用于上下左右方向。
那么如何结合所有方向来检测挥动中的Wigdet?
谢谢!

您可以将“ PageView”用作另一个“ PageView”的子代:
class _TrainigState extends State<TrainingPage> {
PageController hPagerController = PageController(keepPage: true);
PageController vPagerController = PageController(keepPage: true);
double mWidth;
double mHeight;
@override
Widget build(BuildContext context) {
mWidth = MediaQuery.of(context).size.width;
mHeight = MediaQuery.of(context).size.height;
return PageView(
controller: hPagerController,
children: [
_verticalPageView([Colors.blue, Colors.purpleAccent, Colors.pinkAccent, Colors.orangeAccent]),
_verticalPageView([Colors.yellow, Colors.orange, Colors.deepOrange, Colors.red]),
_verticalPageView([Colors.green, Colors.lightGreenAccent, Colors.greenAccent, Colors.lightBlueAccent]),
],
);
}
Widget _verticalPageView(List colors) {
return PageView(
controller: vPagerController,
scrollDirection: Axis.vertical,
children: [
Container(
width: mWidth,
height: mHeight,
color: colors[0],
),
Container(
width: mWidth,
height: mHeight,
color: colors[1],
),
Container(
width: mWidth,
height: mHeight,
color: colors[2],
),
Container(
width: mWidth,
height: mHeight,
color: colors[3],
),
],
);
}
}
我希望它对您有用。
