Rg.Plugins.Popup: PushPopupAsync() returns before popup is actually displayed

@tlhintoq my code can await until popup is closed, or not await, depends on the logic 😃

public async Task ShowMyPopupAsync(object context, bool waitUntilClosed = false)
{
     var myPopup = new MyPopup { BindingContext = context };
     if (waitUntilClosed)
          await myPopup.PopupClosedTask;
}

and your Page (which you showing as popup) will contain next:

public partial class MyPopup : Rg.Plugins.Popup.Pages.PopupPage
{
     private TaskCompletionSource<bool> taskCompletionSource;
     public Task PopupClosedTask { get { return taskCompletionSource.Task; } }

     public MyPopup()
     {
          InitializeComponent();
     }

     protected override void OnAppearing()
     {
          base.OnAppearing();
          taskCompletionSource = new TaskCompletionSource<bool>();
     }

     protected override void OnDisappearing()
     {
          base.OnDisappearing();
          taskCompletionSource.SetResult(true);
     }
}

You can also make PopupClosedTask as interface and implement for any Page

This is just what I was looking for. With the new tuple support in c#, I can easily return multiple objects without having to create a new class. In my popup, I am accepting a string for a prompt which is stored in a UserText property. I also have an Accept and Cancel button. The Accept button assigns ‘true’ to an Accepted property. Then your OnDisappearing method becomes.

private TaskCompletionSource<(bool isAccepted , string userText)> _taskCompletionSource;
public Task<(bool isAccepted, string userText)> PopupClosedTask => _taskCompletionSource.Task;

protected override void OnDisappearing()
{
     base.OnDisappearing();
     taskCompletionSource.SetResult((Accepted, UserText));
}

My calling code looks like…

await PopupNavigation.Instance.PushAsync(inputPopup,true);
var ret = await inputPopup.PopupClosedTask;

Debug.WriteLine($"{ret.isAccepted} - {ret.userText}");

Thanks.
