Vocabulary

Before app launch

Run these commands from project root to generate necessary files:

flutter pub get

and

dart run build_runner build --delete-conflicting-outputs

This app uses the ElevenLabs TTS API to pronounce vocabulary words.

An API key is required for text-to-speech functionality to work.
If no API key is provided, the app will not be able to announce words.

🔑 Providing the API Key

You can provide the API key via an environment variable. Example:

flutter run --dart-define=TTS_API_KEY=your_api_key

Replace your_api_key with the actual key obtained from https://elevenlabs.io.

How to get an API key:

1. Go to https://elevenlabs.io/ and sign up.
2. Go to https://elevenlabs.io/app/settings/api-keys and create your API key.
3. Run flutter app as described above.
