just_physics_engine 0.1.0

Standalone 2D/3D physics engine for Flutter — collision detection, rigid bodies, ray casting, and spatial grids.

0.1.0 - 2026-05-11

Initial release of just_physics_engine.

Added

• 2D rigid-body simulation with PhysicsEngine and PhysicsBody.
• Core physical properties including gravity, drag, restitution, friction, torque, and sleeping.
• Collision shapes: CircleShape, RectangleShape, and PolygonShape.
• Broad-phase collision culling via SpatialGrid.
• Collision resolution with impulse response, friction, and positional correction.
• Runtime simulation stats via engine.stats.
• Debug rendering support via engine.renderDebug.
• 2D ray utility helpers with Ray and Ray.fromPoints.
• Initial 3D API scaffolding stubs: PhysicsEngine3D

Notes

• This release targets Dart SDK ^3.11.0 and Flutter >=1.17.0.
• 2D simulation is production-ready; 3D APIs are currently stubs/scaffolding.
