Composable calls are not allowed inside the calculation parameter of inline fun-CodePudding

I am trying to access the dao instance of my room database which is being used to store names(This code I wrote just to get familiar to jetpack compose).

I tried to access my dao instance inside my composable function but is giving me this error -> Composable calls are not allowed inside the calculation parameter of inline fun remember(calculation: () -> TypeVariable(T)): TypeVariable(T)

My Code

@Composable
fun HomeScreen(navController: NavController){
 var dao by remember{
     mutableStateOf(NameDatabase.getInstance(LocalContext.current).getDao())
 }
 var scope = rememberCoroutineScope()
 var username by rememberSaveable{ mutableStateOf("") }
 Column(
     modifier = Modifier.fillMaxSize(),
     horizontalAlignment = Alignment.CenterHorizontally,
     verticalArrangement = Arrangement.Center
 ){
     OutlinedTextField(value = username, onValueChange = {username=it})
     Spacer(modifier = Modifier.height(10.dp))
     Button(onClick = {
         navController.navigate("showScreen/$username")

     }) {
         Text("Submit")
     }
 }
}

I am getting the error on this line mutableStateOf(NameDatabase.getInstance(LocalContext.current).getDao())

Specifically LocalContext.current is giving this error.

PS: I have resolved this error but want to know what is the meaning of this error any why I can't get the dao instance inside remember.

CodePudding user response：

You need to read the value outside of the function:

val context = LocalContext.current
var dao by remember {
    mutableStateOf(NameDatabase.getInstance(context).getDao())
}
