show method

void show()

Show the overlay child of the OverlayPortal this controller is attached to, at the top of the target Overlay.

When there are more than one OverlayPortals that target the same Overlay, the overlay child of the last OverlayPortal to have called show appears at the top level, unobstructed.

If isShowing is already true, calling this method brings the overlay child it controls to the top.

This method should typically not be called while the widget tree is being rebuilt.


void show() {
  final _OverlayPortalState? state = _attachTarget;
  if (state != null) {;
  } else {
    _zOrderIndex = _now();
