About #
Puro is a powerful tool for installing and upgrading Flutter versions, it is essential for any
developers that work on multiple projects or have slower internet.
With Puro 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 #
Puro is distributed as a precompiled executable (you do not need Dart installed), see the quick installation
instructions at https://puro.dev/
Quick start #
Once puro is installed, set up a new environment with the create command:
# Create a new environment from branch
puro create my_env stable
# Or from a version
puro create my_env 3.3.6
# Or from a commit
puro create my_env d9111f6
# Or from a fork
puro create my_env --fork [email protected]:pingbird/flutter.git

Inside a Flutter project, run the use command to switch to the environment you created:

Puro will automatically detect if you are using VSCode or Android Studio (IntelliJ) and generate the necessary configs.
If this is a new project without a workspace, add --vscode or --intellij to generate them regardless.
You can also configure the global default with --global or -g:
puro use -g my_env

Performance #
Puro implements a few optimizations that make installing Flutter as fast as possible.
First-time installations are 20% faster while improving subsequent installations by a whopping 50-95%:
This also translates into much lower network usage:
How it works #
Puro achieves these performance gains with a few smart optimizations:
Parallel git clone and engine download
Global cache for git history
Global cache for engine versions
With other approaches, each Flutter repository is in its own folder, requiring you to download and store the git history, engine, and framework of each version:
Puro implements a technology similar to GitLab's object deduplication to avoid downloading the same git objects over and over again. It also uses symlinks to share the same engine version between multiple installations:
