Creating Animations for Google’s Mobile Platforms
summary
A concrete system for runtime animations: the Rive editor plus open source runtimes that load a compact binary and run at 60fps on Android Flutter and the Web. Demonstrated a working indeterminate loader "electric sheep" that blends multiple timelines and named animations, controlled from code. Android runtime uses Kotlin + Skia with a small custom view render loop (~25 lines); core is C++; Android AAR ~1.5MB; web is wasm 37KB + JS 14KB and gzipped animations <10KB. Private beta available.
