requests_inspector 🕵

A Flutter package for logging API requests (RESTful API & GraphQL) requests and accessing it by

To get the RequestsInspector widget on your screen:

• Shaking your phone OR
• Long-Press on any free space on the screen.

Also you can share the request details as (Log or cURL command) with your team to help them debug the API requests.

From Inspector to Postman 🧡 🎉️ Now you can extract cURL command from the inspector to send the request again from your terminal or Postman 💪💪

First, add it at the top of your MaterialApp with enabled: true.

void main() {
  runApp(const RequestsInspector(
    enabled: true,
    child: MyApp(),
  ));
}

1. RESTful API:

Note: Don't forget to enable it!

Then, on your API request add a new RequestDetails using RequestInspectorController filled with the API data.

InspectorController().addNewRequest(
    RequestDetails(
        requestName: requestName,
        requestMethod: RequestMethod.GET,
        url: apiUrl,
        queryParameters: params,
        statusCode: responseStatusCode,
        responseBody: responseData,
        ),
    );

OR, if you are using Dio, then you can just pass RequestsInspectorInterceptor() to Dio.interceptors and we are good to go 🎉️🎉️.

final dio = Dio()..interceptors.add(RequestsInspectorInterceptor());

Real Restful example

a. Normal InspectorController().addNewRequest.

Future<List<Post>> fetchPosts() async {
  final dio = Dio();
  final params = {'userId': 1};

  final response = await dio.get(
    'https://jsonplaceholder.typicode.com/posts',
    queryParameters: params,
  );

  final postsMap = response.data as List;
  final posts = postsMap.map((postMap) => Post.fromMap(postMap)).toList();

  InspectorController().addNewRequest(
    RequestDetails(
      requestName: 'Posts',
      requestMethod: RequestMethod.GET,
      url: 'https://jsonplaceholder.typicode.com/posts',
      queryParameters: params,
      statusCode: response.statusCode ?? 0,
      responseBody: response.data,
    ),
  );

  return posts;
}

b. Using RequestsInspectorInterceptor.

Future<List<Post>> fetchPosts() async {
  final dio = Dio()..interceptors.add(RequestsInspectorInterceptor());
  final response = await dio.get('https://jsonplaceholder.typicode.com/posts');

  final postsMap = response.data as List;
  final posts = postsMap.map((postMap) => Post.fromMap(postMap)).toList();

  return posts;
}

Finlay, Shake your phone to get the Inspector

2. GraphQl:

To use requests_inspector with graphql_flutter library. you jus need to wrap your normal HttpLink with our GraphQLInspectorLink and we are done.

Example:

 Future<List<Post>> fetchPostsGraphQlUsingGraphQLFlutterInterceptor() async {
 Future<List<Post>> fetchPostsGraphQlUsingGraphQLFlutterInterceptor() async {
  final client = GraphQLClient(
    cache: GraphQLCache(),
    link: Link.split(
      (request) => request.isSubscription,
      GraphQLInspectorLink(WebSocketLink('ws://graphqlzero.almansi.me/api')),
      GraphQLInspectorLink(HttpLink('https://graphqlzero.almansi.me/api')),
    ),
  );
  const query = r'''query {
    post(id: 1) {
      id
      title
      body
    }
    }''';

  final options = QueryOptions(document: gql(query));
  final result = await client.query(options);
  if (result.hasException) {
    log(result.exception.toString());
  } else {
    log(result.data.toString());
  }
  var post = Post.fromMap(result.data?['post']);
  return [post];
}

For Web, Windows, MacOS and Linux

Obviously, The shaking won't be good enough for those platforms 😅

So you can specify showInspectorOn with ShowInspectorOn.LongPress.

void main() {
  runApp(const RequestsInspector(
    enabled: true,
    showInspectorOn: ShowInspectorOn.LongPress
    child: MyApp(),
  ));
}

OR, you can just pass ShowInspectorOn.Both to open the Inspector with Shaking or with LongPress.

void main() {
  runApp(const RequestsInspector(
    enabled: true,
    showInspectorOn: ShowInspectorOn.Both
    child: MyApp(),
  ));
}

Future plans

• Add support for GraphQL.
• Enhance the GraphQL request and response displaying structure.
• Improve the request tab UI and add expand/collapse for each data block.
• Add search inside the request details page.
