How to store field value from firestore in Flutter?

Question

For example, in the image below, I would like to store the value "hi" in a string in Flutter from Firestore. However, when I print the value, I keep getting Instance of 'Future<dynamic>'

Any idea how to do this?

Edit: One thing I am trying to do is basically get the data and see if its equal to a specific value. For example, if the field text is equal to "hello", then I would print "hi" to the screen

Code:

final firestoreInstance = FirebaseFirestore.instance;
final FirebaseAuth auth = FirebaseAuth.instance;

Future<String> getString(docID) async {
  String? roleValue = '';
  DocumentSnapshot docSnapshot = await firestoreInstance
      .collection('messages')
      .doc(docID)
      .get();

  roleValue = docSnapshot.data()!['text'];
  return roleValue;
}

Seems like you are not awaiting the call as this is an async function. You have to add await just before calling the getString function.

final result = await getString('abc);
print(result);

Now the result will no more Instance of 'Future<dynamic>'
