There was a problem hiding this comment. The error message "Unknown error" is hardcoded. It should be moved to a string resource to support internationalization. |

Instantiating the
ViewModeldirectly inside thecomposableblock causes a new instance to be created on every recomposition. Furthermore, since it's not obtained through aViewModelStoreOwner(e.g., usingviewModel()), itsonCleared()method will never be called, leading to a resource leak of theHttpClientinsideGitHubApiClient. Consider using a proper ViewModel provider that respects the navigation backstack lifecycle.
