A modern programming language that makes developers happier.

kotlinlang

```rememberLauncherForActivityResult(ActivityResultContracts.GetContent()) { uri -&gt;
   if (uri != null) {
       // I want uri to file 
      uri.toFile() // error
   }
}```
I got the content uri of the image from the code above.
I want to send this image file to the server using retrofit, how do I do that?

When I used uri.toFIle() to use the code below, I got an error.
```fun File.toImageMultipartBody(key: String): MultipartBody.Part =
    MultipartBody.Part.createFormData(
        name = key,
        filename = name,
        body = asRequestBody("image/*".toMediaType())
    )```
`error : Uri lacks 'file' scheme: <content://media/external/images/media/9>`
