ussd_service 0.0.3+1

A Flutter plugin to make silent USSD requests and read their responses, using Android's sendUssdRequest. iOS is not supported.

Ussd plugin for Flutter

This plugin makes it possible to access Android's sendUssdRequest method from a Flutter application.

Installation

Add ussd_service as a dependency in your pubspec.yaml.

Make sure that your AndroidManifext.xml file includes the following permission:

<uses-permission android:name="android.permission.CALL_PHONE" />

Usage

Before you use this plugin, you must:

• make sure that the user has authorized access to his phone calls, for example with the permission_handler plugin.
• retrieve the SIM card subscription ID, for example with the sim_service plugin.

You may then use the plugin:

import 'package:ussd_service/ussd_service.dart';

makeMyRequest() async {
  int subscriptionId = 1; // sim card subscription ID
  String code = "*21#"; // ussd code payload
  try {
    String ussdResponseMessage = await UssdService.makeRequest(subscriptionId, code);
    print("succes! message: $ussdResponseMessage");
  } catch(e) {
    debugPrint("error! code: ${e.code} - message: ${e.message}");
  }
};

makeMyRequest();
