Flutter Code Quizzy Application

---

Configuration for this application

Besides the Flutter development setup on your computer, this project needs a quizapi.io API key. The key is not stored in the repo — it is passed in at build time and read via String.fromEnvironment:

flutter run   --dart-define=QUIZ_API_KEY=qa_sk_your_api_key
flutter build --dart-define=QUIZ_API_KEY=qa_sk_your_api_key

In VS Code, add it to .vscode/launch.json instead so you don't have to pass it every time:

{
  "configurations": [
    {
      "name": "code_quizzy",
      "request": "launch",
      "type": "dart",
      "toolArgs": ["--dart-define=QUIZ_API_KEY=qa_sk_your_api_key"]
    }
  ]
}

Without the key the app shows a "Missing API Key" screen rather than failing silently.

The app talks to the v1 API, which authenticates with an Authorization: Bearer <key> header and returns its payloads inside a {success, data, meta} envelope. Topics are loaded at runtime from GET /api/v1/categories, so the topic list never goes stale.

You've done entire steps correctly and I make sure that this project will have paramount effect on your progress learning Flutter
