open method
- Offset? position,
Opens the menu that this MenuController is associated with.
If position
is given, then the menu will open at the position given, in
the coordinate space of the RawMenuAnchor that this controller is
attached to.
If given, the position
will override the MenuAnchor.alignmentOffset
given to the MenuAnchor.
If the menu's anchor point is scrolled by an ancestor, or the view changes size, then any open menu will automatically close.
Implementation
void open({Offset? position}) {
assert(_anchor != null);
_anchor!.handleOpenRequest(position: position);
}
