Why does AvatarView.ImageSource disallow null?

[proudust]

AvatarView is very useful, but I don't understand why AvatarView.ImageSource is not [AllowNull].

With the current specification, in order to display AvatarView.Text, I have to set AvatarView.ImageSource = null;. However, an NRT warning appears, so I am disabling the warning by using null!.

Am I possibly using it incorrectly? If my usage is correct, there might be a need to change it so that AvatarView.ImageSource = null; does not produce an NRT warning.

If you have a look at the Samples app, and go to the Pages/Views/AvatarView/AvatarViewBindablePropertiesPage.xaml and it's view model ViewModels/Views/AvatarView/AvatarViewBindalbePropertiesViewModel.cs you can see examples of using both an ImageSource AND only a text label. Note that the ImageSource property is not defined for the text only AvatarView.

		new AvatarModel
		{
			Description = "Zoe Saldana",
			Text = "ZS",
			TextColor = Colors.Yellow,
			BackgroundColor = Colors.Blue,
			ImageSource = "avatar_icon.png", // Using local MauiImage
			BorderWidth = 2,
			Padding = 10,
			WidthRequest = 64,
			HeightRequest = 64,
			FontSize = 16,
			CornerRadius = new CornerRadius(32),
			BorderColor = Colors.Yellow,
			FontAttributes = FontAttributes.Bold,
		},

		new AvatarModel
		{
			Description = "Sigourney Weaver",
			Text = "SW",
			TextColor = Colors.Yellow,
			BackgroundColor = Colors.Green,
			BorderWidth = 3,
			Padding = 5,
			WidthRequest = 48,
			HeightRequest = 64,
			FontSize = 14,
			CornerRadius = new CornerRadius(16, 16, 0, 0),
			BorderColor = Colors.Pink,
			FontAttributes = FontAttributes.Bold,
		},

Which produces:
