DisplayPrompt not working and not even showing...

[loleczekqdev]

Description

Tried to test out the display alert for my app and it's not even showing.
Am I doing something wrong?

Steps to Reproduce

1. Create .NET Maui App
2. In code behind make a label and use this function on it
   void AddEditableGesture(Label label) { var tapGesture = new TapGestureRecognizer(); tapGesture.Tapped += async (s, e) => { await MainThread.InvokeOnMainThreadAsync(async () => { string result = await DisplayPromptAsync("Question 1", "What's your name?"); }); }; }
3. Observe nothing showing when clicked

At what point do you assign the gesture recognizer to the label in the code above? Perhaps the code is incomplete?

[loleczekqdev]

Turns out you gotta call it from parent element await Application.Current!.Windows[0].Page!.DisplayPromptAsync
Too bad they didnt say nothing about that in documentation..

@loleczekqdev what documentation did you look at? Where did you expect to see it? Just to make sure we mention it in the right place.

There was nothing about it having to be called from the shell

@loleczekqdev are you saying that calling it from the currently displayed page isn't working? It might be helpful if you attached a repro so we can verify if your case is a bug
