About

haven is a powerful tool for superintend Flutter versions, it is essential for any developers that work on multiple projects or have slower internet.

With haven you can:

• Use different versions of Flutter at the same time
• Download new versions twice as fast with significantly less disk space and internet bandwidth
• Use versions globally or per-project
• Automatically configure IDE settings with a single command

Installation

Haven is distributed as a precompiled executable (you do not need Dart installed), see the quick installation.

Quick start

After installing haven you can run haven flutter doctor to install the latest stable version of Flutter, if you want to switch to beta you can run haven use -g beta and then haven flutter doctor again.

And that's it, you're ready to go!

Haven uses the concept of "environments" to manage Flutter versions, these can either be tied to a specific version / release channel, or a named environment that can be upgraded independently.

Environments can be set globally or per-project, the global environment is set to stable by default.

Cheat sheet:

# Create a new environment "foo" with the latest stable release
haven create foo stable

# Create a new environment "bar" with with Flutter 3.13.6
haven create bar 3.13.6

haven upgrade bar 3.10.6
