如何关闭 Navigator.of(context).overlay

Question

使用我的代码：

final CustomOverlay customOverlay = new CustomOverlay(); 
Navigator.of(context).overlay.insert(OverlayEntry(builder: (BuildContext context) { return customOverlay; }));

但是当我想关闭那个 customOverlay 但我不知道如何......

我试过Navigator.of(context).overlay.dispose();

但这不起作用....

使用您的OverlayEntry 中的remove

final customOverlay = new CustomOverlay(); 
final overlayEntry = OverlayEntry(builder: (BuildContext context) { return customOverlay; })); 
overlayEntry.remove();
