fledge_ecs library

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

Fledge ECS provides a high-performance, type-safe ECS architecture with archetype-based storage and concurrent system execution.

Core Concepts

• Entity: A unique identifier for a game object
• Component: Pure data attached to entities
• System: Logic that operates on entities with specific components
• World: The container for all ECS data
• Query: Type-safe iteration over entities with specific components

Example

// Define components
@component
class Position {
  double x, y;
  Position(this.x, this.y);
}

@component
class Velocity {
  double dx, dy;
  Velocity(this.dx, this.dy);
}

// Create world and spawn entities
final world = World();
world.spawn()
  ..insert(Position(0, 0))
  ..insert(Velocity(1, 1));

// Query and update
for (final (entity, pos, vel) in world.query2<Position, Velocity>().iter()) {
  pos.x += vel.dx;
  pos.y += vel.dy;
}
