Add a package to a mono repository

In this part, we are going to add a package to an existing mono-repo.

Open a terminal and go to the packages folder.

Go to the packages folder

cd ~/repos/0000000-demo_mono_repo_app-rubigo/packages

Create a Flutter package

fvm flutter create -t package --org com.example --project-name my_package ./my_package

Open/restart Android Studio

Android studio might not detect the new folder. Restarting Android Studio fixes that.

Commit package

From now on we will use Android Studio to review and commit files.

Choose “Commit”

Add package as a module

Android Studio => File -> Project Structure => Modules => + => Import Module

Navigate to my_package folder and choose “Open”. Be aware that the initial folder that Android Studio suggests might not be part of your current project.

Select “Create module from existing sources”, choose “Next”Choose “Next”Choose “Next”Choose “OK”

Add package as a dependency

Open demo/mono/repo/app/pubspec.yaml and add my_package, and run pub get.

Change main.dart to use package

If you change the line _counter++ to the sample here below, the demo app will use the package to add the values. Hot reload also works while you make changes to the implementation in my_package, which is awesome.

Commit changes to main.dart

Choose “Commit”


These are all the steps that are needed to add a package to the mono-repo.
