To get started, first install the package: 
dart pub add static_map
Then, initialize the SDK with your API key. You can do this in your main function:
lib/main.dart
import 'package:static_map/static_map.dart';

void main() {
    // Initialize the SDK with your API key
    StaticMap.initialize(apiKey: '12345678');
    
    runApp(MyApp());
}
Done! You can now use the SDK to create static maps in your Flutter application. See the Usage section for more information.
