Learn how Flutter handles packages compared to others like npm and yarn.

Hi 👋 My name is Luke and I am a software developer. During my years of working with JS package managers, I’ve never thought things could be done differently. I just accepted that it works as it works. Until I started working with Flutter. Something clicked. Here are my thoughts 👇

I’ll mainly compare Flutter package/dependency management soluton to npm since most major front-end frameworks have it build in.

What we’re all used to and how Flutter does it

Most front-end frameworks are built around package managers like npm, that download and store dependencies in every project directory under well known, dark whole size, directory node_modules.

So if you are a dev that works on multiple front-end projects you surely have few node_modules directories. The thing is — devs are creatures of habit and we usually have our go-to picks when it comes to packages we use. It’s safe to say that every one of those node_modulse will have similar if not the same dependencies. It wouldn't be a problem if node_modules weren’t that big every time.

For example:

You work on three regular, non Flutter, front-end projects, where node_module weights on average about 600 MB that roughly 1.8GB of memory allocated just for those dependencies.

That's how everything looked before Flutter.
