Conclusion

In this lesson, you learned:

• The purpose of DataStore.
• The difference between DataStore and SharedPreferences.
• How to save and read data from DataStore.

You learned how to use DataStore to save simple data in your app. DataStore is a modern persistence solution from Google that provides type safety, error handling, asynchronous operations, and observing data changes.

You learned that DataSore is a replacement for SharedPreferences. SharedPrerences was the go-to solution for storing simple data in Android, but it has some limitations. DataStore, as part of the Jetpack Libraries, addresses these limitations.

You also learned how to create a DataStore instance, write data to DataStore, and read data from DataStore. You used Kotlin coroutines and Flow to perform asynchronous operations and observe data changes from your DataStore.

DataStore is the recommended data storage solution for an Android app. Use it to store simple data such as user preferences, settings, configurations, and to access tokens for authenticating your network calls.

Congratulations! You have completed this lesson on saving user data with DataStore.
