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

# Switch "bar" to a specific Flutter version
haven upgrade bar 3.10.6
