Access of global variables in dart / flutter
1,896
The underscore _
before a variable name means that the variable is private.
A global variable should be a public variable, a public variable on the other hand should begin without the _
By changing "final _firestore = Firestore.instance" to "final firestore = Firestore.instance" you should be able to access your variable globally.
Another way to make your private variable to be accessed on global level is by adding a getter like this: Firestore get firestore => _firestore;

I can't seem to access my global variables _firestore and loggedInUser from a different class in flutter / dart. From what I read in the documentation and online, this should be possible?
Creating the global variables:
import 'package:cloud_firestore/cloud_firestore.dart'; final _firestore = Firestore.instance; FirebaseUser loggedInUser; class TheSlateScreen extends StatefulWidget {
Trying to access them here:
import 'package:theslate/screens/theslate_screen.dart'; class SlateTasks extends ChangeNotifier { void addTask(String newTaskTitle) { _firestore.collection('Test').add({ 'Task': newTaskTitle, 'User': loggedInUser.email, });
