Provider in `didChangeDependencies` does not update data - flutter

Question

I'm initializing the data in my provider in didChangeDependencies in the parent widget.
#override
void didChangeDependencies() {
super.didChangeDependencies();
final provider = Provider.of<NewArrivalsProvider>(context);
FirebaseFirestore.instance.collection(CurrentUser.getCurrentUser().uid).doc('newArrivals').get().then(
(snapshot) {
Map<String, dynamic> data = snapshot.data();
provider.init(data);
},
);
}
Then updating the data in the child widget.
The change in the data is does not persist however.
Switch(
value: item.value,
onChanged: (state) => provider.update(key: item.key, state: state),
)
Only one switch changes value at a time.
class NewArrivalsProvider extends ChangeNotifier {
Map<String, dynamic> _items = {};
Map<String, dynamic> get items => _items;
int get length => _items.length;
void init(Map<String, dynamic> data) {
_items = data['mapUrls'];
}
void update({#required String key, #required bool state}) {
_items.update(key, (value) => value = state);
notifyListeners();
}
}
Since this is the first I used Provider in the didChangeDependencies method, I'm suspecting that's where the error is. Am I correct?

Answer 1

I solved it.
I changed the provider declaration in the didChangeDependencies to
final provider = Provider.of<NewArrivalsProvider>(context, listen: false);
When listen: true, this line listens to the changes I make to the data.
Then it downloads the data again from Firestore (which is set to false initially)
The change to listen: false makes line run only when the user navigates to the page and does not update every time I change the data
