This animation expands/collapses an arc that's 3/4ths of a circle. The next iteration begins where the previous appeared to finish. This happens while the whole thing rotates, such that the starting point of each expansion moves in a star-wise pattern around the circle. See: https://www.google.com/design/spec/components/progress-activity.html (note: the video here demonstrating this animation is actually slightly incorrect... we'll hopefully update it soon)
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.
