Sphere loader flutter animation
Animated Wave Ripple Logo
A sleek, physics-inspired loading animation that creates a mesmerizing stack of animated ellipses with dynamic color transitions. Perfect for loading states, brand logos, or eye-catching UI elements.
Technical Composition
**Core Animation**: Stack of 10 ellipses with orchestrated vertical movement using `AnimationController`
**Color System**: Dynamic HSL color interpolation (280° → 140° hue range) with 0.9 opacity
**Physics Simulation**: Cosine-based size and height calculations for natural motion
**Rendering**: Custom painter for efficient ellipse drawing
**Performance**: Optimized using minimal repaints and efficient transform calculations
Key Features
Smooth enter/exit transitions with size interpolation
Fluid color gradients with HSL color space
Configurable speed, size, and opacity
Minimal memory footprint using single `AnimationController`
Responsive scaling with maintained aspect ratios
