I want it to popup or not to popup by receiving the On and Off events.
I received the On event and popped it up. Off event has [await Navigation.PopAllPopupAsync(false); ] to clear the popup.
There are cases where the off event comes in twice. If there is no currently popped page, await Navigation.PopAllPopupAsync(false); will throw an exception. So I want to know if there is a flag to know if there is currently popped screen.

Navigation.PopAllPopupAsyncin Xamarin. Do you use third-party plugins?So I want to know if there is a flag to know if there is currently popped screen.
There is no such an API to determine whether a pop-up window exists, you could use a static variable to record the status of a pop-up window, which is simple and effective.
