Стоит ли использовать каркас на каждом экране? Что такое лучшие практики при использовании Topbar, Bottombar, ящика и т. ⇐ Android

[Anonymous]

Я пишу приложение для Android Pure в Compose, и я использую каркас на каждом экране для реализации Topbar, Bottombar, Fab и т. Д. Лот, но нигде не нашел ответа, даже JetPack Compose Sample Приложения не предоставляют ничего о лучших практиках для создания приложения в JetPack Compose.
Пожалуйста, может ли кто -нибудь помочь мне. < /p>
Мой код выглядит так, как это < /p>
MainActivity < /p>
@AndroidEntryPoint
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

setContent {
PasswordManagerApp()
}
}
}

@Composable
fun PasswordManagerApp() {

val mainViewModel: MainViewModel = hiltViewModel()
val navController = rememberNavController()
val systemUiController = rememberSystemUiController()
val scaffoldState = rememberScaffoldState()
val coroutineScope = rememberCoroutineScope()

Theme(
darkTheme = mainViewModel.storedAppTheme.value
) {

Scaffold(
scaffoldState = scaffoldState,
snackbarHost = { scaffoldState.snackbarHostState }
) {

Box(modifier = Modifier) {

AppNavGraph(
mainViewModel = mainViewModel,
navController = navController,
scaffoldState = scaffoldState
)

DefaultSnackbar(
snackbarHostState = scaffoldState.snackbarHostState,
onDismiss = { scaffoldState.snackbarHostState.currentSnackbarData?.dismiss() },
modifier = Modifier.align(Alignment.BottomCenter)
)

}

}
}
}
