I Couldn't Find a Rolling Text Library for Compose, So I Built One

Short summary

To display changing prices in a crypto app with satisfying 'odometer' animations, a developer built compose-rolling-text after existing Compose animation libraries fell short. The breakthrough solution uses graphicsLayer for GPU-accelerated translation, avoiding expensive layout passes. Post details the iterative problem-solving journey, failed approaches, and key implementation insights including easing curves and responsive font sizing.
