Как сохранить текстовые данные, которые вводит пользователь в Android? ⇐ Android

[Гость]

Я создал приложение, которое отображает список коз с основной информацией, такой как имя, возраст, порода и дополнительной информацией (необязательно). Пользователь может запустить диалоговое окно для каждой козы и ввести текст имени, возраста, породы и дополнительную информацию. Также можно ввести изображение с помощью библиотеки катушек.
Как сохранить данные, которые пользователь вводит для каждого козла, чтобы они отображались при следующем запуске приложения?
Я новичок в этом и не имею опыта сохранения данных.
Вот код:
class MainActivity : ComponentActivity() {
//private val viewModel by viewModels()
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

setContent {
GoatsTheme {
// A surface container using the 'background' color from the theme
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colorScheme.background
) {

GoatsApp(viewModel = MainViewModel())

}

}
}
}
}

@Composable
fun GoatsApp(viewModel: MainViewModel) {

var goats: MutableList = remember {
mutableStateListOf(
Goats(R.string.red, R.string.alpine, 7),
Goats(R.string.little_goat, R.string.alpine, 8),
Goats(R.string.nana, R.string.alpine, 7),
Goats(R.string.sharkie, R.string.alpine, 10)
)
}

var bucks: MutableList = remember { mutableStateListOf(
Goats(R.string.billy, R.string.mix, 7)
) }

var isButtonClicked by mutableStateOf(false)
