Remarks
The SKCanvasView provides a software-rendered drawing surface for SkiaSharp graphics in .NET MAUI applications. For GPU-accelerated rendering, consider using SKGLView instead.
Subscribe to the PaintSurface event to draw custom graphics using the SKCanvas provided in the event arguments.
To request a redraw, call InvalidateSurface(). The view also supports touch events when EnableTouchEvents is set to true.
The underlying platform views are:
- Android:
SKCanvasView(Android) - iOS/Mac Catalyst/tvOS:
