close method

void close()

Close the menu that this menu controller is associated with.

Associating with a menu is done by passing a MenuController to a MenuAnchor. A MenuController is also be received by the MenuAnchor.builder when invoked.

If the menu's anchor point (either a MenuBar or a MenuAnchor) is scrolled by an ancestor, or the view changes size, then any open menu will automatically close.

Implementation

void close() {
  assert(_anchor != null);
  _anchor!._close();
}
