Examples of DataStore usage in production apps?

DataStore is a reactive data storage solution in Android that provides a simple and efficient way to manage application settings, preferences, and other small data. In production applications, it allows developers to efficiently read and write key-value pairs or typed objects while ensuring that data operations are performed asynchronously.

// Example of using DataStore in a production app class PreferencesManager(private val dataStore: DataStore) { val someKey: Flow = dataStore.data .map { preferences -> preferences[stringPreferencesKey("some_key")] ?: "default_value" } suspend fun saveSomeKey(value: String) { dataStore.edit { preferences -> preferences[stringPreferencesKey("some_key")] = value } } } // Usage in ViewModel class MyViewModel(private val preferencesManager: PreferencesManager) : ViewModel() { val someKeyFlow: LiveData = preferencesManager.someKey.asLiveData() fun setSomeKey(value: String) { viewModelScope.launch { preferencesManager.saveSomeKey(value) } } }
