# Add a plugin to a mono repository

In this part, we are going to add a plugin 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 plugin

```
fvm flutter create -t plugin --platforms ios,android --org com.example --ios-language objc --android-language java --project-name my_plugin ./my_plugin
```

### Open/restart Android Studio

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

### Commit plugin

We will use Android Studio to review and commit files.

### Add plugin as a module

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

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

### Change main.dart to use plugin

With some small changes, we can call MyPlugin.platformVersion, which gets information about the current OS.
