blob_flutter 1.1.0 
blob_flutter: ^1.1.0 copied to clipboard
A highly customizable and performant 3D particle blob effect for Flutter.
1.1.0 #
- True 3D Object-Space Shaders (
uColor3D): Gradients rotate dynamically with the 3D geometry in world space instead of remaining flat in 2D screen space. - $O(N)$ Linear Depth Sorting & Depth-Cueing (
enableDepthSort,enableDepthCueing): Zero-allocation 64-bin Bucket Sort in isolate ensures proper back-to-front rendering order (Painter's algorithm) with atmospheric depth scaling. - Responsive Auto-Fit (
autoFit,radiusFactor): Automatically resizes the blob radius to dynamically fit parent container dimensions and screen orientation changes. - Flutter Web Optimization (
isComplex,webTemporalInterleaving): Alternates calculation frames (striding) to slash per-frame CPU math on single-threaded JavaScript, with configurable particle limits (maxWebParticles). - Zero-Battery Multi-Tier Lifecycle (
autoPauseOffscreen,autoPauseOnAppBackground,autoPauseOnRouteChange): Automatically halts tickers and isolate calculations (0% CPU/GPU) when offscreen, minimized, or when navigating to another route.
1.0.0 #
- Initial release of
blob_flutter. - High-performance interactive 3D particle blob powered by custom GPU fragment shaders (
blob.frag). - Multi-threaded background computation via dedicated worker
Isolate. - Procedural noise models (Smooth Waves, Spikes, Cellular, Wrinkles, Crystal, Swirl, Organic Pulse, Custom).
- Fluid multi-touch drag rotation, hover tracking, and tap dispersion physics.
- Zero-allocation render loop using pre-allocated buffers and
Canvas.drawRawPoints. - Robust error handling hierarchy (
BlobShaderException,BlobWorkerException,BlobParameterException) with fallback UI (errorBuilder,onError).
