CupertinoContextMenu class

A full-screen modal route that opens when the child is long-pressed.

When open, the CupertinoContextMenu shows the child, or the widget returned by previewBuilder if given, in a large full-screen Overlay with a list of buttons specified by actions. The child/preview is placed in an Expanded widget so that it will grow to fill the Overlay if its size is unconstrained.

When closed, the CupertinoContextMenu displays the child as if the CupertinoContextMenu were not there. Sizing and positioning is unaffected. The menu can be closed like other PopupRoutes, such as by tapping the background or by calling Navigator.pop(context). Unlike PopupRoute, it can also be closed by swiping downwards.

The previewBuilder parameter is most commonly used to display a slight variation of child. See previewBuilder for an example of rounding the child's corners and allowing its aspect ratio to expand, similar to the Photos app on iOS.

This sample shows a very simple CupertinoContextMenu for the Flutter logo. Long press on it to open.
