Flame: game loops inside Flutter

Flame is how Flutter does games without abandoning the widget tree for a different engine. A GameWidget hosts a component tree updated by a game loop; overlays keep HUD/chat in normal Flutter.

Steal this

1. Hybrid UI: game canvas + Flutter overlays for menus/monetization.
2. Bridge packages (audio, physics, tiled, bloc) keep the core small.
3. Deterministic updates help tests and replays.

Pitfalls

• Mixing setState UIs into the game loop fights the architecture.
• Mobile thermal budgets matter more than desktop FPS flexes.

Use Flame for 2D product mini-games and interactive canvases, not only toys.
