drawWithCache & Performance
Avoid rebuilding draw objects each frame.
Drawing Runs Often
Your Canvas lambda can run on every frame. Rebuilding heavy objects there, frame after frame, quietly drags down performance.
The Costly Objects
Things like Path, Brush, and Paint are not free to create. Allocating them on each draw wastes work the GPU never needed.
