How to Use CustomPaint and Canvas in Flutter for Drawing

In Flutter, the CustomPaint widget and Canvas class allow developers to draw custom graphics directly onto the screen, making it ideal for creating complex shapes, animations, and interactive designs.

To begin, wrap your widget with CustomPaint and assign it a custom painter class using the painter property. The painter class must extend CustomPainter and override two key methods: paint(Canvas canvas, Size size) and shouldRepaint().

In the paint() method, you can use the Canvas API to draw lines, circles, rectangles, paths, and more using the Paint class for styling. For example:

dart

canvas.drawCircle(Offset(100, 100), 50, Paint()..color = Colors.blue);

Using CustomPaint and Canvas gives developers low-level control for creating visually rich, performance-optimized UI elements, especially for apps that require drawing, charts, games, or dynamic visual effects.
