CustomPainter & Canvas

Flutter's widgets are powerful, but sometimes you need to draw something truly unique. Think custom graphs, unique shapes, or special visual effects!

This is where custom drawing comes in. It gives you pixel-level control over what appears on the screen, letting you create anything imaginable.

At the heart of custom drawing in Flutter is the CustomPainter class. You extend this class to define what and how to draw.

• It provides a canvas to draw on.
• It requires you to implement two key methods: paint and shouldRepaint.
