flutter_activity_recognition 4.0.0

This plugin is used to recognize user activity on Android and iOS platforms.

This plugin is used to recognize user activity on Android and iOS platforms. To implement this plugin, Android used ActivityRecognitionClient and iOS used CMMotionActivityManager.

Features

• Can request activity recognition permission.
• Can subscribe to ActivityStream to listen activity in real time.

Getting started

To use this plugin, add flutter_activity_recognition as a dependency in your pubspec.yaml file. For example:

dependencies:
  flutter_activity_recognition: ^4.0.0

After adding the flutter_activity_recognition plugin to the flutter project, we need to specify the platform-specific permissions to use for this plugin to work properly.

🐤 Android

Open the AndroidManifest.xml file and add the following permissions between the <manifest> and <application> tags.

<uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" />
<uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION" />

🐤 iOS

Open the ios/Runner/Info.plist file and add the following permission inside the <dict> tag.

<key>NSMotionUsageDescription</key>
<string>Used to recognize user activity information.</string>

How to use

1. Checks whether activity recognition permission is granted.

Future<bool> _checkAndRequestPermission() async {
  ActivityPermission permission =
      await FlutterActivityRecognition.instance.checkPermission();
  if (permission == ActivityPermission.PERMANENTLY_DENIED) {
    // permission has been permanently denied.
    return false;
  } else if (permission == ActivityPermission.DENIED) {
    permission =
        await FlutterActivityRecognition.instance.requestPermission();
    if (permission != ActivityPermission.GRANTED) {
      // permission is denied.
      return false;
    }
  }

  return true;
} 

2. To listen activity in real time, use the activityStream getter.

StreamSubscription<Activity>? _activitySubscription;

Future<void> _subscribeActivityStream() async {
  if (await _checkAndRequestPermission()) {
    _activitySubscription = FlutterActivityRecognition.instance.activityStream
        .handleError(_onError)
        .listen(_onActivity);
  }
}

void _onActivity(Activity activity) {
  print('activity detected >> ${activity.toJson()}');
}

void _onError(dynamic error) {
  print('error >> $error');
}

Background Mode

If you want to use this plugin in the background, use the flutter_foreground_task plugin.
