The key insight: instead of dynamically changing column counts on a single FlashList (which causes janky layout recalculations), the approach stacks multiple pre-rendered grids with fixed column counts (1, 3, 5, 9 columns) and cross-fades between them during pinch gestures. Virtualization via FlashList/LegendList makes rendering multiple complete grids performant. The technique has been open-sourced as the `react-native-zoom-grid` npm package. The app also integrates AI features like Gemini-powered photo editing and bulk tagging via natural language prompts, built using the Coreviz SDK. ## Full article daily.dev links to this article rather than hosting it.
