Answer from AI

In Jetpack Compose, the functions remember and rememberSavable are used to preserve state across recompositions of composable functions, but they differ in how they save the state:

  • remember saves the state only in memory during the current lifecycle of the composition. When the activity or process is recreated, the state will be lost.

  • rememberSavable saves the state in a way that it can be automatically saved and restored during activity recreation, such as during screen rotation. This uses the SavedInstanceState mechanism.

Example:

var count by remember { mutableStateOf(0) } // state is not saved during activity recreation

var count by rememberSavable { mutableStateOf(0) } // state is saved and restored

Use rememberSavable if you want the state to be preserved during configuration changes.
