Data Representations

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

• Android
• iOS

Example usage

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

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

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