SignedIn

The SignedIn composable conditionally renders its content only when the user is authenticated. It reads the current sign-in state from LocalThunderID and displays protected UI for signed-in users, while rendering optional fallback content (or nothing) when the user is not authenticated.

SignedIn requires ThunderIDProvider in its ancestor composable hierarchy.

Usage

import dev.thunderid.compose.components.guards.SignedIn

@Composable
fun ContentView() {
    SignedIn {
        Text("You are signed in.")
    }
}

When the user is not signed in, nothing is rendered unless you provide a fallback lambda.

Parameters

Parameter	Type	Required	Description
fallback	(@Composable () -> Unit)?	❌	The composable to render when the user is not authenticated. Defaults to nothing.
content	@Composable () -> Unit	✅	The composable to render when the user is authenticated.

Providing a Fallback

Show alternative content when the user is not signed in:

SignedIn(
    fallback = { AuthView() }
) {
    HomeView()
}

Example: Route Between Screens

Use SignedIn and SignedOut together to implement your app's root navigation:

@Composable
fun RootView() {
    val thunder = LocalThunderID.current

    when {
        !thunder.isInitialized || thunder.isLoading -> {
            CircularProgressIndicator()
        }
        else -> {
            SignedIn(fallback = { AuthView() }) {
                HomeView()
            }
        }
    }
}
