This seems to be working as as expected according to the error message.
You can a build widget during build phase which is triggered by the secondary tap down in the sample
Try updating the open calling in a post frame callback, this is called after the widget finish building.
SchedulerBinding.instance!.addPostFrameCallback((Duration timeStamp) {
if (widget.position != oldWidget.position) {
_menuController.open(position: widget.position);
}
});from flutter.

Whoops sorry @TahaTesser -- I forgot to come back to this issue! Yeah, I wasn't sure whether it was an actual issue considering this is just the standard behavior of overlays. I did notice that the code for closing the menu contains a check for schedulerphase, so I wasn't sure if it was overlooked for opening or if this is expected behavior.
I also wasn't sure if there should be a "declarative" way of opening the menu. For example, web dialogs have an "open" parameter that will trigger their showing, rather than users having to call a function or otherwise having to wait for a frame. But if it's expected behavior, we can close this issue! Sorry for the trouble.
