Why I'm Learning Flame Before Unity

Flame Flutter Unity Game Dev Learning

Picking the engine that lets me write game code this weekend, not next quarter.

Every "how to become a game dev" article online tells you the same thing: pick Unity or Unreal, start with a tutorial, build a small game, repeat.

I'm not doing that. I'm learning Flame — a 2D game engine built on Flutter — first. Here's why, and why you might consider it too if you're coming from mobile.

The cost of switching tools

When you learn a new field, every kind of unfamiliarity adds drag. New language. New IDE. New mental model. New error messages. New community. New ecosystem.

Each of these is small on its own. Stack them up and you spend three months fighting your tools before you write a single line of actual game logic.

Unity is a beautiful engine. It's also C#, MonoBehaviour, the Unity editor, the asset pipeline, prefabs, scenes, scriptable objects, the package manager, and a thousand other concepts that aren't game design — they're just Unity. If I went there first, I'd be learning Unity, not games.

Flame is Dart. I already know Dart. It's a normal Flutter package — I flutter pub add flame and I'm running. The editor is VS Code, which I've spent five years in. The debugger is the same debugger I use at work. The build process is flutter run.

That means 100% of my learning energy goes into the part I actually don't know: game design itself.

What you're actually learning

The fundamentals of game development don't live in any specific engine:

  • Game loops and delta time
  • Sprite rendering and animation
  • Collision detection
  • Camera systems
  • Input handling
  • State machines for entity behavior
  • ECS or component patterns
  • Audio
  • Asset loading and management

Flame teaches all of these. They're the same concepts you'd learn in Unity, just expressed in code instead of in an editor. And here's the thing — when you eventually migrate to Unity or Godot, those concepts come with you. You'll spend a week learning the new tool, not a year.

The honest tradeoffs

I'd be lying if I said Flame is the right choice for everyone. It isn't. Some real tradeoffs:

Flame is small. Smaller team, smaller community, fewer tutorials, fewer assets, fewer Stack Overflow answers. When you hit a weird bug, you're more likely to be on your own.

Flame is 2D-first. There's experimental 3D, but if you want to make a 3D game, you're in the wrong place.

Flame won't get you a job at a game studio. Studios use Unity or Unreal. If your goal is to be hired as a junior game dev next year, learn what studios use.

The tooling is sparser. No visual editor. No drag-and-drop scene builder. You write code for everything. For some people this is freedom; for others it's friction.

Why those tradeoffs work for me

My goal isn't to get a game studio job. It's to learn enough that I can ship interesting things — small games, prototypes, weird experiments — while I figure out where this is taking me. For that, I want momentum. I want to write code on Sunday and have something running by dinner.

Flame gives me that. The first game I made — a tiny endless runner — was working in a day, because I didn't have to learn anything new about builds, deployment, debugging, or my IDE. I just had to learn what update(dt) means.

The second reason: I want to keep my Flutter skills sharp. Flame lives inside Flutter. Building a game in Flame is building a Flutter app, just with a different render target. Every hour I spend on a Flame game is also an hour of staying fluent in Dart.

When I'll switch

I will eventually move to Unity or Godot. Not because Flame is wrong, but because I'll outgrow it. The moment I want to make something genuinely 3D, or I want to use assets from the Unity asset store, or I want to collaborate with non-programmers who think in editors, the math changes.

But by then, I'll have spent a year or two building actual games. I'll know what a game loop feels like. I'll know how to design a collision system. I'll know how to scope a project so it actually ships. Switching engines at that point is a week of tooling, not a year of fundamentals.

The general principle

I think the broader lesson, beyond games, is this: when you're learning a new field, minimize the non-essential unfamiliarity. Pick the tool that lets you spend the most time on what you're actually trying to learn, not the tool that's most popular or most powerful or most future-proof.

For me, with my background, that's Flame. For you it might be Godot, or Unity, or pico-8, or making text adventures in Python. The right answer is the one that lets you write your first game this weekend, not next quarter.
