iOS MediaPicker.CapturePhotoAsync closes the wrong modal

[jasells]

Description

After MediaPicker.CapturePhotoAsync() returns the FileResult, the Camera modal is still on screen. If subsequent code tries to open a modal like:

        var photo = await MediaPicker.CapturePhotoAsync();
        Debug.WriteLine($"===== FileResult from cam: {photo?.FullPath.ToString() ?? "null"}");

        if (photo == null) { return new CropResult(); }
        
        SKBitmap bmp;
        using (var imStr = await photo.OpenReadAsync())
        {
            bmp = SKBitmap.Decode(imStr);
        }

        var tcs = new TaskCompletionSource<CropResult>();

        var saved = (CropResult x) =>
            {
                onCropComplete?.Invoke(x);
                tcs.TrySetResult(x);
            };

        // this modal/page won't show as written, though it works on Android, Windows.
        var navt = Application.Current?.MainPage?
                                       .Navigation
                                       .PushModalAsync(new ImageCropperPage(imageCropperConfig,
                                                                            saved));

the new modal won't display or is closed with the Camera modal?

I think the task from .CapturePhotoAsync() is returning before the Camera modal close() + close animations are complete, and so it is also closing the new modal just added to stack?

Steps to Reproduce

Build/run the app for iOS (I am currently using Rider). In app, click the "test" link btn on bottom right, then click "From Camera" btn.

Did you find any workaround?

yes.

this code is the work around, by dispatching the call to Application.Current?.MainPage?.Navigation.PushModalAsync() I think it allows the new modal navigation run after MediaPicker.CapturePhotoAsync() completes the camera display UI close animation, and everything works as expected.

return await _dispatcher.DispatchAsync(() => ShowAsync((SKBitmapImageSource)bmp,
                                                               imageCropperConfig,
                                                               onCropComplete));
