ecsly 0.0.1-dev.4

Experimental ECS core for Dart/Flutter (early prerelease).

ecsly (Entity Component System) for Dart/Flutter

⚠️ This package is published as super-experimental prerelease (0.0.1-dev.4). APIs are actively changing and may break across releases.

ecsly is a high-performance Dart ECS runtime focused on deterministic simulation and low-GC hot loops. It owns entities, archetypes, resources, events, commands, and schedules.

Use

Add to pubspec.yaml:

dependencies:
  ecsly: ^0.0.1-dev.4

Import path:

import 'package:ecsly/ecsly.dart';

What this package is and is not

• ✅ Core runtime package: entities, archetypes, resources, events, plugins, and system schedules.
• ✅ Runtime-first with minimal external dependencies and early-prerelease status.
• ❌ Not a code-generator package: use ecs_codegen only where annotation-based code generation is needed.
• ❌ Not a full application stack: graphics/input/collision/camera plugins live in sibling package folders.
