    public partial class CameraPage : ContentPage

        public CameraPage()
        {
            InitializeComponent();
        }
        async void EscolherIMG(System.Object sender, System.EventArgs e)
        {
            var result = await MediaPicker.PickPhotoAsync(new MediaPickerOptions
            {
                Title = "Por favor uma imagem"
            });
            var stream = await result.OpenReadAsync();
            resultIMG.Source = ImageSource.FromStream(() => stream);
        }
        async void TirarFT(System.Object sender, System.EventArgs e)
        {
            var result = await MediaPicker.CapturePhotoAsync();
            var stream = await result.OpenReadAsync();
            var image = await result.OpenReadAsync();
            var file = await CrossMedia.Current.TakePhotoAsync(new Plugin.Media.Abstractions.StoreCameraMediaOptions
            {
                Directory = "Fotos Tiradas",
                Name = "Foto.pdf"
            });
        }
    }
