Data Store

What is Data Store

• Datastore is a component of data storage solution from the android jetpack.
• It allows us to store the key/value pairs like shared preferences or typed objects with protocol buffers.
• Data store uses kotlin, coroutines, and flow to store data asynchronously with consistency and transaction support

Why use datastore when we already have shared preferences

• Shared Preferences are synchronous and not main thread-safe, But data store is safe to use in the main thread since it uses Dispatchers.IO under the hood.
• Shared Preferences are not safe from runtime exceptions, But the Data-Store is safe from runtime exceptions
• There is an easy way to migrate from Shared Preferences

Type of Data Store

Preference Data Store	Proto Data Store

Demo represents how the data-store is used

• Here we have a fragment where we are storing a value entered in edit-text, on click of save button, We have used global scope here
• We are displaying the data from the dataManager helper class that gets the data from the data store via a flow and displays the data in the text view
• View <->ManagerClass
