FirebaseFirestore _firestore = FirebaseFirestore.instance;
I have to do this instead of firestore _ firestore=..
Still it gives error in the 'documents'. Please help!

W/Firestore( 8804): (22.0.2) [WriteStream]: (f90275f) Stream closed with status: Status{code=PERMISSION_DENIED, description=Cloud Firestore API has not been used in project 893369919060 before or it is disabled. Enable it by visiting https://console.developers.google.com/apis/api/firestore.googleapis.com/overview?project=893369919060 then retry. If you enabled this API recently, wait a few minutes for the action to propagate to our systems and retry., cause=null}.

this is my rule in realtime database

{
"rules": {
".read": "now < 1615573800000", // 2021-3-13
".write": "now < 1615573800000", // 2021-3-13
}
}

it creates the user under Authentification/users

but nothing is created under database\data

and the app logs in but all screens are without data.

please help me solve this issue, thanks,

steps to reproduce:
i have migrated the code to update firebase dependency,
then i have no errors showing except a depreciated plugin "stripe_payment"

can't run the app .....

NoSuchMethodError: The getter 'iterator' was called on null.
Receiver: null
Tried calling: iterator

Future _onStateChanged(FirebaseUser firebaseUser) async{
if(firebaseUser == null){
_status = Status.Unauthenticated;
print("null user");
}else{
_user = firebaseUser;
_status = Status.Authenticated;
_userModel = await _userServicse.getUserById(user.uid);
}
notifyListeners();
}

.endAt([searchKey+ '\uf8ff'])

the code is not working anymore

is there any other alternative?

Hey @Santos-Enoque, I'm following the course but also making a few additions of my own to challenge myself, I'm having trouble with accessing the nested cart inside the orders list. I'm basically trying to unpack that Cart Map inside the List of orders so I can read that data

import 'package:flutter/material.dart';
import 'package:flutter_test/flutter_test.dart';
import 'package:food_app/scr/screens/login.dart';

void main() {
testWidgets('Counter increments smoke test', (WidgetTester tester) async {
// Build our app and trigger a frame.
await tester.pumpWidget(MyApp()); error line

// Verify that our counter starts at 0.
expect(find.text('0'), findsOneWidget);
expect(find.text('1'), findsNothing);

// Tap the '+' icon and trigger a frame.
await tester.tap(find.byIcon(Icons.add));
await tester.pump();

// Verify that our counter has incremented.
expect(find.text('0'), findsNothing);
expect(find.text('1'), findsOneWidget);

});
}

Future signUp() async{
try{
_status = Status.Authenticating;
notifyListeners();
await _auth.createUserWithEmailAndPassword(email: email.text.trim(), password: password.text.trim()).then((result){
_firestore.collection('users').document(result.user.uid).setData({ error line
"name": name.text,
"email": email.text,
"id": result.user.uid
});
});
return true;
}catch(e) {
return _onError(e.toString());
}
}

Please I can't find my way around the codes for the missing video. Could you please share that with me? Thank you
