In the file, score_screen.dart (28 line)
It doesn't display the score correctly

Instead of using
_qnController.correctAns* 10

Use
_qnController.numOfCorrectAns * 10

I added a retry button on scorePage and then start again it shows me an error as
The page property cannot be read when multiple PageViews are attached to the same PageController.

I thought if someone wants to retry again then he/she could start the quiz as fresh as in start of the app.

Help me solve this.....

Can you please provide a link so that everyone can download the similar background svgs? It will be a great resource.

I'm a beginner of flutter. download from git . after run "flutter pub get" ,the VsCode report an error “Evaluation of this constant expression throws an exception.“

This app is using a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to migrate this app to the V2 embedding.
Take a look at the docs for migrating an app: https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects

According to https://docs.flutter.dev/release/breaking-changes/buttons

The FlatButton, RaisedButton and OutlineButton widgets have been replaced by TextButton, ElevatedButton, and OutlinedButton respectively.

On Debug Console, "Using a widget function instead of a widget fully guarantees that the widget and its controllers will be removed from memory when they are no longer used."

Resolve :
In file: question_controller.dart & welcome_screen.dart

Instead of using
Get.to(ScoreScreen());
Get.to(QuizScreen())

Use
Get.to(() => ScoreScreen());
Get.to(() => QuizScreen())
