Flutter + HTTP

DataDome Flutter Integration

DataDome Flutter plugin is an adaptation of the DataDome iOS and Android SDKs to Flutter. The plugin provides an interface to make networking requests to ensure your app networking layer is protected with DataDome.

Install the plugin

To install the plugin, add the DataDome dependency to your pubspec.yaml file as shown in the following

dependencies:
  datadome: ^1.0.0
  flutter:
    sdk: flutter

Note: Make sure your project does support Swift/Kotlin. If not, enable Swift/Kotlin for your Flutter project by executing the following command

flutter create -i swift -a kotlin

For iOS:

Update the Info.plist file of the iOS project under ios/Runner/Info.plist:

1. Add a new entry with the key DataDomeKey and your DataDome client side key as value.
2. Add a new entry with the key DataDomeProxyEnabled and NO as value (make sure the type of the entry is Boolean).

Now the plugin is ready to be used.

Usage

The DataDome Flutter plugin provides a set of APIs to perform networking requests. The plugin will perform a request, intercept any signal from the DataDome remote protection module, display a captcha if relevent and then retry the failed request.
This is all managed by the DataDome client.

Initialize the DataDome client

Make sure you create an instance of the DataDome client

DataDome client = DataDome('YOUR_DATADOME_CLIENT_SIDE_KEY');

Depending on the request type, use one of the following APIs from the client instance you just created.

Perform GET/DELETE requests

Use the get or delete method from the DataDome client to perform the GET/DELETE request

Future<http.Response> get({
    @required String url,
    Map<String, String> headers = const {}
}) async

Future<http.Response> delete({
    @required String url,
    Map<String, String> headers = const {}
}) async

The method takes the following arguments:

• url A string representation of the request URL.
• headers An optional Map of header fields and values.

The method executes the request and return a Response instance from the http package

Here a sample code to perform a GET request

//importing needed packages
import 'package:datadome/datadome.dart';
import 'package:http/http.dart' as http;

//creating the DataDome client
DataDome client = DataDome('DATADOME_CLIENT_SIDE_KEY');

//performing a GET request
http.Response response = await client.get(url: 'https://datadome.co/wp-json');

//using the response            
print('Response status: ${response.statusCode}');
print('Response headers: ${response.headers}');
print('Response body: ${response.body}');
            

Perform POST/PUT/PATCH requests

Use one of the following methods from the DataDome client to perform the desired request

POST

Future<http.Response> post({
      @required String url,
      Map<String, String> headers = const {},
      body
}) async

PUT

Future<http.Response> put({
      @required String url,
      Map<String, String> headers = const {},
      body
}) async

PATCH

Future<http.Response> patch({
      @required String url,
      Map<String, String> headers = const {},
      body
}) async

The above methods take the following arguments:

• url A string representation of the request URL.
• headers An optional Map of header fields and values.
• body The request body in List or Map data types.

The method executes the request and return a Response instance from the http package

Here a sample code to perform a POST request

//importing needed packages
import 'package:datadome/datadome.dart';
import 'package:http/http.dart' as http;

//creating the DataDome client
DataDome client = DataDome('DATADOME_CLIENT_SIDE_KEY');

//performing a POST request
http.Response response = await client.post(url: 'https://jsonplaceholder.typicode.com/posts', body: {'title': 'foo', 'body': 'bar', 'userId': '1'});

//using the response            
print('Response status: ${response.statusCode}');
print('Response headers: ${response.headers}');
print('Response body: ${response.body}');
            

Forcing the Captcha display

We use the User-Agent header with the value BLOCKUA to hint the remote module to block the request.
Please note that the captcha is displayed once and then the generated cookie is stored locally.

Here a sample code to perform a GET request while forcing a captcha display

//importing needed packages
import 'package:datadome/datadome.dart';
import 'package:http/http.dart' as http;

//creating the DataDome client
DataDome client = DataDome('DATADOME_CLIENT_SIDE_KEY');

//performing a GET request with the BLOCKUA User-Agent header
http.Response response = await client.get(url: 'https://datadome.co/wp-json', headers: {'User-Agent': 'BLOCKUA'});

//using the response            
print('Response status: ${response.statusCode}');
print('Response headers: ${response.headers}');
print('Response body: ${response.body}');
            

IMPORTANT Do not leave this header in production. This will lead all users to see a captcha at least once.
