Monorepo support

FVM helps ensure that all projects or packages within a monorepo utilize a consistent Flutter SDK version. This consistency is crucial for avoiding compatibility issues and streamlining the development process. Here's how you can leverage FVM effectively in two common monorepo setups:

Melos: Monorepo with a Shared pubspec.yaml

A shared pubspec.yaml at the monorepo's root is beneficial for projects with common dependencies, ensuring they all adhere to a unified Flutter SDK version.

Melos requires a pubspec.yaml at the root of the monorepo. Running fvm use at the root of the monorepo will generate a .fvmrc file to be generate at the root, and will allow or packages to use the same Flutter SDK version.

Specify the Flutter SDK version in melos.yaml. This configuration ensures that all scripts and Melos commands utilize the designated Flutter SDK version, maintaining consistency across the monorepo.

For detailed configuration instructions, refer to the sdkPath (opens in a new tab) in Melos documentation.

Project with Subfolders

This setup involves repositories segmented into subfolders, with each housing a distinct Flutter project, and lacking a unified monorepo management tool.

Run fvm use at the root folder of the Flutter projects to generate a .fvmrc file. Now, each project can use the same Flutter SDK version.
