An accelerometer sensor library for Flutter.

awareframework_accelerometer

The accelerometer measures the acceleration applied to the sensor built-in into the device, including the force of gravity.

Install the plugin into project

1. Edit pubspec.yaml

dependencies:
    awareframework_accelerometer

2. Import the package on your source code

import 'package:awareframework_accelerometer/awareframework_accelerometer.dart';

Public functions

Accelerometer Sensor

• start()
• stop()
• sync(bool force)
• enable()
• disable()
• isEnable()
• setLabel(String label)

Configuration Keys

• frequency: Int: Data samples to collect per second (Hz). (default = 5)
• period: Double: Period to save data in minutes. (default = 1)
• threshold: Double: If set, do not record consecutive points if change in value is less than the set value.
• enabled: Boolean Sensor is enabled or not. (default = false)
• debug: Boolean enable/disable logging to Logcat. (default = false)
• label: String Label for the data. (default = "")
• deviceId: String Id of the device that will be associated with the events and the sensor. (default = "")
• dbEncryptionKey Encryption key for the database. (default = null)
• dbType: Engine Which db engine to use for saving data. (default = 0) (0 = None, 1 = Room or Realm)
• dbPath: String Path of the database. (default = "aware_accelerometer")
• dbHost: String Host for syncing the database. (default = null)

Data Representations

The data representations is different between Android and iOS. Following links provide the information.

• Android
• iOS

Example usage

// init config
var config = AccelerometerSensorConfig()
  ..debug = true
  ..label = "label";

// init sensor
var sensor = new AccelerometerSensor.init(config);

void method(){
    /// start 
    sensor.start();
    
    /// set observer
    sensor.onDataChanged.listen((AccelerometerData data){
      setState((){
        // Your code here
      });
    });
    
    /// stop
    sensor.stop();
    
    /// sync
    sensor.sync(true);  
    
    // make a sensor care by the following code
    var card = new AccelerometerCard(sensor:sensor);
    // NEXT: Add the card instance into a target Widget.
}
