If you change the RenderObject tree between frames, you'll assert if you subsequently hit test. So e.g. if you get two button presses back to back, and you mutate the tree synchronously in response to the first one, the second will assert. This adds an onBuild callback to WidgetToRenderBoxAdapter to make it easier to do the updates at the right time, i.e., during widget build. It'll be called whenever you rebuild the WidgetToRenderBoxAdapter itself, so all you have to do to use it is call setState() on whoever is building the WidgetToRenderBoxAdapter.
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.
