Pedometer #

This plugin allows for continuous step counting and pedestrian status using the built-in pedometer sensor API of iOS and Android devices.

Permissions #
For Android 10 and above add the following permission to the Android manifest:
<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" />

For iOS, add the following entries to your Info.plist file in the Runner xcode project:

<string>This application tracks your steps</string>
<key>UIBackgroundModes</key>
<array>
<string>processing</string>
</array>

Step Count #
The step count represents the number of steps taken since the last system boot.
On Android, any steps taken before installing the application will not be counted.
Pedestrian Status #
The Pedestrian status is either walking or stopped. In the case that of an error,
the status will be unknown.
Availability of Sensors #
Both Step Count and Pedestrian Status may not be available on some phones:

It was found that some Samsung phones do not support Step Count or Pedestrian Status
Older iPhones do not support Pedestrian Status in particular

In the case that the step sensor is not available, an error will be thrown. The application needs to handle this error.
Example Usage #
See the example app for a fully-fledged example.
Below is shown a more generalized example. Remember to set the required permissions, as described above. This may require you to manually allow the permission in the "Settings" on the phone.
Stream<StepCount> _stepCountStream;
Stream<PedestrianStatus> _pedestrianStatusStream;

/// Handle step count changed
void onStepCount(StepCount event) {
int steps = event.steps;
DateTime timeStamp = event.timeStamp;
}

/// Handle status changed
void onPedestrianStatusChanged(PedestrianStatus event) {
String status = event.status;
DateTime timeStamp = event.timeStamp;
}

/// Handle the error
void onPedestrianStatusError(error) {}

/// Handle the error
void onStepCountError(error) {}

Future<void> initPlatformState() async {
// Init streams
_pedestrianStatusStream = await Pedometer.pedestrianStatusStream;
_stepCountStream = await Pedometer.stepCountStream;

// Listen to streams and handle errors
_stepCountStream.listen(onStepCount).onError(onStepCountError);

_pedestrianStatusStream
.listen(onPedestrianStatusChanged)
.onError(onPedestrianStatusError);
