I’m new to Flutter and Dart, and I’m trying to build an app that allows users to sign in with Google and allows them to choose a Google Sheet to use with the app from the Google Sheets they have in their Drive. When the app starts, I perform the following asynchronous tasks for which I am using a FutureBuilder –

FutureBuilder(
future:Future.value( FirebaseFirestore.instance.collection(‘users’).doc(userId).get(),),
builder: (context, snapshot) {
if (snapshot.connectionState == ConnectionState.waiting) {
return const Text(“Loading…”);
} else if (snapshot.hasError || snapshot.data == null) {
return const Text(“User not found”);
}
