## What it is
Flame is an open-source 2D game engine built on top of Flutter, providing a game loop, component system, collision detection, effects, particles, and input handling. It runs on mobile, desktop, and web and includes bridge packages for audio, physics, Tiled maps, and more.

## Use cases
- build a 2d mobile game with flutter
- make a cross-platform game from a single codebase
- create a browser game with dart
- add collision detection and sprites to a flutter game
- build a roguelike or rpg in flutter
- ship a casual game to ios and android

## When to choose
- you already know Flutter/Dart and want to build 2D games
- you need one codebase targeting mobile, desktop, and web
- you want a batteries-included engine with game loop, collisions, particles, and input out of the box
- you prefer a community-driven, MIT-licensed engine

## When to avoid
- you need 3D rendering or advanced console-grade features
- you require maximum raw performance outside Flutter's rendering model
- your team works in Unity, Godot, or another non-Dart ecosystem
