particles_network 1.9.6

A performant and customizable interactive particle network widget for Flutter. Ideal for background animations, landing pages, and visual effects.

CHANGELOG

1.9.6

Added

• Adaptive Performance Engine: Introduced AdaptivePerformanceController and enableAdaptivePerformance to dynamically adjust rendering quality and connection density based on real-time FPS monitoring.
• Fast Line Rendering: Added fastLineRendering (with useVerticesRendering alias) for high-efficiency batch line drawing with minimal GPU draw calls.
• Connection Density Limiting: Added maxConnectionsPerParticle to bound edge generation to $O(N)$ complexity instead of $O(N^2)$, enabling high particle counts without frame drops.
• Adaptive Density Scaling: Added adaptiveDensity to automatically scale connection radius in dense particle regions.
• Advanced Touch Physics: Added TouchFeatures configuration support (speed/decayRate, force/pullForce, damping, maxTouchSpeed, lineDistance) for fine-grained gesture control.
• Trajectory Direction Preservation: Improved physics engine to maintain true velocity angle vectors during particle deceleration and inertia settling.
• Expanded Test Suite: Added extensive unit tests for CompressedQuadTree subdivision, uninsertable boundary particles, TouchFeatures physics, and painter repaint optimizations.

1.9.5

• Added optional mouse hover support on Desktop and Web (hoverEffect).
• Implemented interactive particle network system with spatial partitioning (Compressed QuadTree).
• Added zero-allocation Color LUT (_lineColorLut) and Touch Inactivity Bypass.
• Added deterministic trajectory precomputation (TrajectoryBuffer).
• Added global and point gravity simulation.
• Improved rendering performance using GPU Fragment Shaders.
