# User management

```
data class User(
    val uid: String,
    val name: String,
    val email: String,
    val picture: FileUrl?,
)
```

```
val saveProfilePicture = SaveProfilePicture(args) // args are injected thanks to Koin
saveProfilePicture(byteArray)
```

### Save Profile Picture

Imagine you want to create a ProfileScreen that save picture profile selected via gallery ou camera to the local file system and remote storage: 

```
class ProfileScreenModel(
    private val saveProfilePicture: SaveProfilePicture,
): ScreenModel {
    fun saveProfilePicture(byteArray) {
        this.saveProfilePicture(byteArray)
    }
}


```

SaveProfilePicture saves in local file system the image then tries to send it to the remote storage. 

### Control the remote storage

suspend fun putFileAt(localFile: LocalFile, location: String): FileUrl
