Overview
Metaballs is a Flutter package that creates fluid, dynamic metaball effects using WebGL on the web and the shader package on native platforms. It enables smooth, interactive visualizations with organic, merging shapes that respond to user input or animation. Ideal for background animations, abstract interfaces, and immersive UIs, it leverages GPU acceleration for high performance across Android, iOS, Web, macOS, Windows, and Linux. The package simplifies complex shader logic into an easy-to-use API, making advanced visual effects accessible to developers without deep graphics knowledge.
Use cases
- Interactive app backgrounds
- Animated splash screens
- Abstract UI elements
- Visualizers for data or music
- Dynamic gradient overlays
Key features
