This package provides a single class, Client, which allow to send messages to your mobile phone by using the sendMessage() method:

import 'package:free_mobile/free_mobile.dart';

Future main() async {
  try {
    var client = new Client('<user name>', '<identification key>');
    await client.sendMessage('Hello World!');
    print('The message was sent successfully.');
  catch (Exception error) {
    print('An error occurred: $error');

The text of the messages will be automatically truncated to 160 characters: you can't send multipart messages using this library.


The Client class triggers some events during its life cycle:

  • request : emitted every time a request is made to the remote service.
  • response : emitted every time a response is received from the remote service.

These events are exposed as Stream, you can listen to them using the on<EventName> properties:

  (request) => print('Client request: ${request.url}')

  (response) => print('Server response: ${response.statusCode}')

Unit tests

In order to run the tests, you must set two environment variables:

$ export FREEMOBILE_USERNAME="<your Free Mobile user name>"
$ export FREEMOBILE_PASSWORD="<your Free Mobile identification key>"

Then, you can run the test script from the command prompt:

$ pub run test
