What it is
Melos is a command-line tool for managing Dart and Flutter projects, including workspaces with multiple packages in a monorepo. It links local packages, installs workspace dependencies and can synchronize shared dependencies and run lifecycle scripts during bootstrap. Commands can run across packages simultaneously and be narrowed by scope, category, changed packages, Flutter dependencies or package dependencies. Melos can also list local packages and their dependencies.
The tool automates package versioning and changelog generation, and can publish packages to pub.dev. It supports CI/CD workflows and provides a GitHub Action; single-package projects can use it for versioning, publishing and changelogs too. IntelliJ support generates project modules and run configurations, while the VS Code extension offers configuration validation, autocompletion, tasks and package graphs. Melos is free, installs globally through Dart Pub and supports Pub as its package manager. Version 8.x.x requires Dart SDK 3.9.0 or newer. Publishing requires permission for all packages and a machine authenticated with Pub; dry-run is enabled by default. IntelliJ integration is documented only for Melos v6 and lower.
