Here my code :

class ExternalApi {
  static Future<List<String>> getPexelsImage(String search, {Dio? dio}) async {
    dio ??= Dio();
    List<String> resultImage = [];
    try {
      final result = await dio.get(
        'https://api.pexels.com/v1/search?query=$search&per_page=50',
        options: Options(
          headers: {
            HttpHeaders.authorizationHeader: Keys.pexelsKey
          }, // Vérifiez si la clé est correcte ici
          contentType: 'application/x-www-form-urlencoded',
        ),
      );
      for (final photo in result.data['photos']) {
        resultImage.add(photo['src']['large']);
      }
      debugPrint('SUCCESS');
      debugPrint(result.headers.toString());
      return resultImage;
    } on DioException catch (e) {
      debugPrint('ERREUR ' + e.toString());

Can someone help me
