movisens_flutter_plugin #

pub package

A plugin for connecting and collecting data from a Movisens sensor. This plugin excelusively works for Android.

Install #

Add movisens_flutter as a dependency in pubspec.yaml. For help on adding as a dependency, view the documentation.

Android permissions #

Add the following to your manifest

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

Example Usage #

A Movisens object is instantiated by providing a UserData object, which is, in essence a Map structure containing a list of required fields for the Movisens sensor. These include: Weight, height, age, sensor address and sensor name.

Intialization: #

Movisens _movisens;
StreamSubscription<MovisensDataPoint> _subscription;
LogManager logManager = new LogManager();
List<MovisensDataPoint> movisensEvents = [];
String address = 'unknown', name = 'unknown';
int weight, height, age;

Start Listening #

Data from the sensor is streamed continuously, which is done by calling the listen() method on a Movisens object. An exception will be thrown if the listen method is invoked on a platform other than Android.

void startListening() {
    address = '88:6B:0F:82:1D:33';
    name = 'Sensor 02655';
    weight = 100;
    height = 180;
    age = 25;
    UserData userData = new UserData(
        weight, height, Gender.male, age, SensorLocation.chest, address, name);
    _movisens = new Movisens(userData);
    try {
      _subscription = _movisens.movisensStream.listen(onData);
    } on MovisensException catch (exception) {

Additionally, it can be a good idea to have a separate method for handling incoming data, such as the onData method shown below:

void onData(MovisensDataPoint d) {
    setState(() {

Stop Listening #

The subscription can be cancelled again, by invoking the cancel method:

void stopListening() {
