Hi guys I am learning side-effect in my project. I want to know when should I use LaunchedEffect and SideEffect in which scenario. I am adding some piece of code using both effect. Please lemme know if I am doing wrong here.

1st using LaunchedEffect, please guide me if we need effect on this function or not.

@Composable
fun BluetoothRequestContinue(multiplePermissionsState: MultiplePermissionsState) {
    var launchPermission by remember { mutableStateOf(false) }
    if (launchPermission) {
        LaunchedEffect(Unit) {
            multiplePermissionsState.launchMultiplePermissionRequest()
        }
    }
    AbcMaterialButton(
        text = stringResource(R.string.continue_text),
        spacerHeight = 10.dp
    ) {
        launchPermission = true
    }
}

2nd using SideEffect to open setting using intent

@Composable
fun OpenPermissionSetting(router: Router = get()) {
    val activity = LocalContext.current as Activity
    var launchSetting by remember { mutableStateOf(false) }
    if (launchSetting) {
        SideEffect {
            activity.startActivity(router.permission.getPermissionSettingsIntent(activity))
        }
    }
    AbcMaterialButton(
        text = stringResource(R.string.open_settings),
        spacerHeight = 10.dp
    ) {
        launchSetting = true

    }
}

Please let me know if we need Effect or not. Also guide me if we need different effect as well. Thanks

@Filip Wiesner I am confused through the doc.

[KotlinLeaner]

That's why I don't understand should I use the side-effect or not..

[Filip Wiesner]

You don't Effect API here at all. You can launch the permission from the button onClick

[KotlinLeaner]

Okk got it now.. Thanks

[Filip Wiesner]

I assume you are using Accompanist permission library. There is code example

[KotlinLeaner]

Yes I am using Accompanist permission library.

Another question in 2nd example

[KotlinLeaner]

I am opening the setting of my application that would be use side effect?

[Filip Wiesner]

It's the basically the same question with the same answer 🙂
