Get Started #
import 'package:leetcode_api_dart/leetcode_api_dart.dart';

final session = "your_leetcode_session_from_cookie";
final csrfToken = "your_leetcode_csrfToken_from_cookie";

void main() {
final api = LeetcodeApiClient(
session: session,
csrfToken: csrfToken,
);

// make api calls
}

You can pass session and csrfToken as empty, however session info will provide additional data such as the user's solve count, submission status, premium data (if applicable to the user), etc.

Make Your Own Call to Leetcode #
Indeed the available APIs may not be sufficient, hence a GraphQL request can be made directly. The following method will only allow us to make GET calls
to prevent the misusage of the API. The method takes one parameter, which is GraphQL request payload as a string
import 'package:leetcode_api_dart/leetcode_api_dart.dart';

extension LeetcodeApiClientCustom on LeetcodeApiClient {
Future<MyCustomModel> getCustomQuery({required String param}) async {
final data = await makeGraphQLRequest(buildMyGraphQLQueryHere(param: param));
return MyCustomModel.fromJson(data);
}
}

// don't forget to add 'r' before the string, in order to pass the $ symbol without stripping it away in dart
String buildMyGraphQLQueryHere({required String param}) => r'''{
"query": "\n query Something() {\n name \nis_blocked \n} \n",
"variables": {}
}''';
