🛰️ NASA API Integration

The project uses NASA’s Astronomy Picture of the Day API.

API endpoint:

https://api.nasa.gov/

The API key is provided at runtime using Flutter’s –dart-define mechanism.

Example:

flutter run -d chrome –dart-define=NASA_API_KEY=YOUR_API_KEY
Important

Do not commit your NASA API key to GitHub.

The project intentionally reads the API key using:

const apiKey = String.fromEnvironment(‘NASA_API_KEY’);

This keeps the key outside the source code.

Note: because this project runs on Flutter Web, values passed with –dart-define can ultimately be exposed in the client application. For a production application, a backend/proxy and appropriate API restrictions should be considered.
