Runtime Error in Net Maui Graphics

Question

I am trying to apply Maui Graphics but it's not as easy as Skiasharp and System.Drawing, because the drawing class is separate, and my skills in object programming are low.

I've been trying for days to create the simplest example that displays dynamic data.

Please help me create the simplest app that displays data in Maui graphics.

my code

Thank you in advance.

Hello,

I've tested your project and made it display dynamic data from the firebase, you could refer to the following code:

   public void Draw(ICanvas canvas, RectF dirtyRect)  
   {  
       canvas.FontColor = Colors.Blue;  
       canvas.FontSize = 18;  
       canvas.Font = Font.Default;  
       FirebaseHelper firebaseHelper = new FirebaseHelper();  
       var books = Task.Run(() => firebaseHelper.GetAllBooksAsync()).Result;  
       int i = 0;  
       foreach (var book in books)  
       {  
           i++;  
           canvas.DrawString(book.Title, 100, 50 * i, HorizontalAlignment.Center);  
       }  
   }

If you want to learn more about GraphicsView, you could refer to this official demo: GraphicsViewDemos.
