Try a reactive approach to update state flow in ViewModels

[dmitriy-chernysh]

class SearchViewModel @Inject constructor(private val searchRepo: SearchRepository): ViewModel() {

    private val _searchQuery = MutableStateFlow("")
    
    val searchResults: StateFlow<List<SearchResult>> = _searchQuery
        .debounce(300) // Add a debounce to limit requests
        .filter(String::isNotEmpty) // Ignore empty queries
        .flatMapLatest(searchRepository::search)
        .stateIn(viewModelScope, SharingStarted.Lazily, emptyList())

    fun setSearchQuery(query: String) {
        _searchQuery.update { query }
    }
}```
