How to store data in Jetpack Compose Desktop?

I am creating an application in Jetpack Compose Desktop which will take user input and after user reopens the application that input value should be there. I mean a user given data should be there after user reopens the application.

remember { mutableStateOf } doesn't work here

I didn't get tag for jetpack compose desktop so I have android Jetpack Compose tag

you can do it using java preferences.

class Preferences {
    private val preferences: Preferences = Preferences.userRoot().node(this::class.java.name)

fun storeData(key: String, value: String) = preferences.put(key, value)
fun getData(key: String): String? = preferences.get(key, null)
fun deleteData(key: String) = preferences.remove(key)

}

you need use sqlite or file to cache data, "remember" just cache to the running memory

One way of doing this is to use the Java Preference API to store Key/Value based values.

If you need more complicated data, you would need to store your data into a File or a database.

The remember will only save data while the current view is visible on the screen. Check out more about state it compose in documentation.

If you need to save something between application runs, you need to save it to a database or write it to a file and read it when the application runs.
