In the main.dart file
create: (_) => FirestoreService().streamReport(),

generates an not found error.

The method 'FirestoreService' isn't defined for the type '_AppState'.
Try correcting the name to the name of an existing method, or defining a method ``named 'FirestoreService'

I need to know if this can be deployed to flutter web

How to assign the schema and data to new firebase project so that we can fetch data from it as show quiz?
Basically want to replace the google-services.json with new project and setup its firestore document

Thanks in advance

I have finished all the quizzes in the app please add more quizzes specially in flutter

Running iOS 12.2 on a iPhone Xs Max, and cant seem to see an image for the Firebase quiz, see attached file.

How to create data from firebase and Schema data firebase.

please give an example data on firebase

db.dart provides an excellent, abstract means to connect Firestore documents and collections to Flutter without all the boilerplate. However, I noticed a bug when working with streams in db.dart. When creating a stream collection, such as by calling:
StreamProvider<List<Example>>.value(value: Global.exampleRef.streamData())

...inside of a MultiProvider widget, you will get the following error message:

An exception was thrown by _MapStrean<QuerySnapshot, List> listened by StreamProvider<List>, but no 'catchError was provided.

Exception: type 'MappedListIterable<DocumentSnapshot, Example>' is not a subtype of type 'List'

In db.dart, Line 47 is missing a .toList() at the end:
Stream<List<T>> streamData() { return ref.snapshots().map((list) => list.documents.map((doc) => Global.models[T](doc.data) as T).toList()); }

Hi it will be good if you could update the repo to using Provider 3.0. Thank you

════════ Exception caught by widgets library ═══════════════════════════════════════════════════════
The following ProviderNotFoundError was thrown building TopicProgress(dirty):
Error: Could not find the correct Provider above this TopicProgress Widget

To fix, please:

• Ensure the Provider is an ancestor to this TopicProgress Widget
• Provide types to Provider
• Provide types to Consumer
• Provide types to Provider.of()
• Always use package imports. Ex: `import 'package:my_app/my_code.dart';
• Ensure the correct context is being used.

If none of these solutions work, please file a bug at:
https://github.com/rrousselGit/provider/issues

User-created ancestor of the error-causing widget was:
Column file:///C:/Users/Guilherme/AndroidStudioProjects/quizapp/lib/screens/topics.dart:65:20

In https://github.com/fireship-io/flutter-firebase-quizapp-course/blob/master/lib/screens/profile.dart

if the user logs out, out of band, like by resetting their password, and they are logged into the app, they'll get an infinite loading screen.

Checking out the master branch at it's latest commit does not work:

* What went wrong:
A problem occurred evaluating project ':cloud_firestore'.
> Could not find method platform() for arguments [com.google.firebase:firebase-bom:26.2.0] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Also
I have followed along on your platform, but yet at the end I am getting this error. In topics.dart

======== Exception caught by rendering library =====================================================
The following assertion was thrown during layout:
A RenderFlex overflowed by 99854 pixels on the bottom.

The relevant error-causing widget was: 
  Column file:///home/arpan/Documents/School/sem4/mobile-apps/quizapp/lib/screens/topics.dart:65:20
The overflowing RenderFlex has an orientation of Axis.vertical.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.

Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.

The specific RenderFlex in question is: RenderFlex#b685a OVERFLOWING
...  parentData: <none> (can use size)
...  constraints: BoxConstraints(w=172.7, h=172.7)
...  size: Size(172.7, 172.7)
...  direction: vertical
...  mainAxisAlignment: spaceBetween
...  mainAxisSize: max
...  crossAxisAlignment: start
...  textDirection: ltr
...  verticalDirection: down

Lots to do to upgrade to the latest firebase. This one has me stumped. The Collection method:

Stream<List> streamData() {
return ref.snapshots().map((list) => list.documents.map((doc) => Global.modelsT as T) );
}
gives:
Expected a value of type 'Map<dynamic, dynamic>', but got one of type '() => Map<String, dynamic>'
