Answer from AI
viewModelScope is a CoroutineScope associated with the lifecycle of a ViewModel in Android. Its main features:
- Coroutines launched in
viewModelScopeare automatically canceled when the ViewModel is destroyed, preventing memory leaks. - It allows convenient launching of asynchronous operations related to the UI without manually managing cancellation.
- Used for working with data, loading from network, database, etc., maintaining architectural purity.
Example usage:
viewModelScope.launch {
val data = repository.loadData()
_state.value = data
}
