Managing Flutter & Dart SDK Versions with Proto

"It works on my machine." Three Flutter projects, three different SDK versions, and flutter downgrade is your most-used command. There has to be a better way — and there is. Proto is a universal version manager (think nvm or asdf , but faster and cross-platform) — and now it supports Flutter and Dart through community WASM plugins. Why proto over FVM or asdf? FVM is Flutter-specific. It works, but it's one more tool in your stack. If you already manage Node, Go, Rust, or Python versions, that's yet another version manager with its own config format. asdf supports many tools via plugins, but it's historically been shell-script based, Unix-only, and can be slow. proto gives you: One tool for all your SDKs (Node, Go, Rust, Python, Flutter, Dart, PHP, and more) Blazing fast — plugins are compiled to WASM, not shell scripts Cross-platform — Linux, macOS, and Windows Per-project version pinning via .prototools (one file, all tools) Automatic version detection from pubspec.yaml Auto-switching
