Instruction

In a previous lesson, you learned about the remember composable function. The remember function saves the state across recomposition. However, the state would be lost when a configuration change occurs.

To save state across a configuration change like screen rotation, use the rememberSaveable composable function. rememberSaveable saves state values in a Bundle object.

This is how you’d create a MutableState object in a composable using the rememberSaveable function:

var friendsName by rememberSaveable { mutableStateOf("") }

In the next lesson, you’ll use rememberSaveable in a hands-on experience to save state across configuration changes in the Wellness Club App.
