route guards flutter
final routes = {
'/': (BuildContext context) => FutureBuilder<AuthState>(
// This is my async call to sharedPrefs
future: AuthProvider.of(context).authState$.skipWhile((_) => _ == null).first,
builder: (BuildContext context, AsyncSnapshot<AuthState> snapshot) {
switch(snapshot.connectionState) {
case ConnectionState.done:
// When the future is done I show either the LoginScreen
// or the requested Screen depending on AuthState
return snapshot.data == AuthState.SIGNED_IN ? JobsScreen() : LoginScreen()
default:
// I return an empty Container as long as the Future is not resolved
return Container();
}
},
),
};
