Could you make the values for roll the same?

The Attitude indicator screen. I want to look at the source code and learn how to implement it.

Hi,

Great package but I'm seeing mixed results with cancelling the stream. I'm recording actions and my app grabs the pitch and roll at the start of a record session, then records events and deducts this first event from each record. I do this because the phone could be at any angle to start with and it needs to be normalised. So grabbing a first value of pitch and roll is vital, and hence I need the stream to close so it doesn't keep updating this value. I use:

_vectorStream = AeyriumSensor.sensorEvents.listen(
      (SensorEvent event) {
        if (event.pitch != null) {
          _sensorVectorOffset = Vector(event.pitch, event.roll);
          _vectorStream.cancel();
        }
      },
    );

Usually this works for the first four or five attempts and then after that it no longer closes the stream, and starts overriding this offset value.

Can you please advise what the issue is and how to close your stream consistently?

It'd be lovely to have.

I have used this library on android (emulator and real device without any problems), however on the iPhone 8 (physical device) the roll sensor value jumps from 0 to approximately 2*pi or 6.28... when the phone lays flat.
Whereas on android it changes from 1 to 0 to -1 for example, when i rotate the device.
I think, the library should give consistent results on android and iOS.
I would prefer it the android way. In the meantime I use this workaraound:

if(Platform.isIOS){
  if(event.roll < (-1)*pi){
    sensorValue = 2*pi+event.roll;
  } 
  else{         
    sensorValue = event.roll;
  }
} 
else{
  sensorValue = event.roll;     //roll in radians for android 
}

Thank you.

It would be great if azimuth could be added.

Hi,

I've copied the example , then at the moment to run shows nothing on device!!

on my debug console says : E/SensorManager( 2627): sensor or listener is null

Can you help me with this, please?

The plugin aeyrium_sensor uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.
