Many of the widgets that use CustomPaint were spamming repaints because CustomPaint repaints when the identity of the onPaint callback changes, which it does every build for StatelessComponents. This patch changes CustomPaint to use a CustomPainter, similar to the new custom layout widgets. The CustomPainter has a `shouldRepaint` function along with its `paint` function. This function gives clients explicit control over when the custom paint object repaints.
Flutter
Flutter is a new way to build high-performance, cross-platform mobile apps. Flutter is optimized for today's, and tomorrow's, mobile devices. We are focused on low-latency input and high frame rates on Android and iOS.
Flutter is an early-stage open-source project. We are still missing core features like accessibility, text input, localization, and more. However, you can build demos and examples today. We hope you try it out and send us feedback.
