fledge_ecs 0.2.0

A Bevy-inspired Entity Component System (ECS) for Dart and Flutter game development.

Changelog

0.2.0 - 2026-09-20

Changed

• Scheduler rewritten around named schedule graph (Schedules + Scheduler); stage: argument on addSystem renamed to schedule:.
• App.tick() restructured to drive extract + render schedules on top of the main schedule.
• Query iterators snapshot archetype membership at iter start, fixing a silent-drop bug when systems spawned/despawned matching entities mid-iteration.

Added

• FixedTimestep resource and fixed-timestep dispatch chain (Schedules.fixedUpdate).
• Query1..4<T> / QueryMut1..4<T> marker types; reads/writes are now inferred from the marker in generator output.
• WallTime / WallTimePlugin for real-time clocks.

Deprecated

• Time / TimePlugin — use WallTime / WallTimePlugin.
