Public Member Functions
	Position (this.point, this.accuracy, this.heading, this.headingAccuracy, this.locationPoint, this.locationHeading)
	Default constructor.

Public Attributes
GlobalPoint	point
	position in WGS84 coordinates.
double	accuracy
double	heading
	Heading, angle of rotation about the -Z axis (in radians). This value represents the angle between the device's Y axis and the magnetic north pole. When facing north, this angle is 0, when facing south, this angle is pi. Likewise, when facing east, this angle is pi/2, and when facing west, this angle is -pi/2. The range of values is [-pi, pi].
double	headingAccuracy
	Heading accuracy in radians.
LocationPoint	locationPoint
	position in metrics coordinates at calculated location and sublocation LocationPoint
double	locationHeading
	Similar to heading but with respect to sublocation north (top of the image)

Member Data Documentation

accuracy

double Position.accuracy

Position accuracy in meters

Dart code snippet:

    // Get position accuracy
    double accuracy = position.accuracy;
    print("Position accuracy: $accuracy meters");

Definition at line 47 of file position.dart.

heading

double Position.heading

Heading, angle of rotation about the -Z axis (in radians). This value represents the angle between the device's Y axis and the magnetic north pole. When facing north, this angle is 0, when facing south, this angle is pi. Likewise, when facing east, this angle is pi/2, and when facing west, this angle is -pi/2. The range of values is [-pi, pi].

Dart code snippet:

    // Get heading (angle of rotation about the -Z axis in radians)
    double? heading = position.heading;
    if (heading != null) {
      print("Heading: $heading radians");
    }

Definition at line 64 of file position.dart.

headingAccuracy

double Position.headingAccuracy

Heading accuracy in radians.

Dart code snippet:

    // Get heading accuracy
    double? headingAccuracy = position.headingAccuracy;
    if (headingAccuracy != null) {
      print("Heading accuracy: $headingAccuracy radians");
    }

Definition at line 75 of file position.dart.

locationHeading

double Position.locationHeading

Similar to heading but with respect to sublocation north (top of the image)

Dart code snippet:

    // Get location heading (with respect to sublocation north)
    double? locationHeading = position.locationHeading;
    if (locationHeading != null) {
      print("Location heading: $locationHeading radians");
    }

Definition at line 97 of file position.dart.

locationPoint

LocationPoint Position.locationPoint

position in metrics coordinates at calculated location and sublocation LocationPoint

Dart code snippet:

    // Get location point (metrics coordinates)
    LocationPoint? locationPoint = position.locationPoint;
    if (locationPoint != null) {
      _demonstrateLocationPointUsage(locationPoint);
    }

Definition at line 86 of file position.dart.

point

GlobalPoint Position.point

position in WGS84 coordinates.

Dart code snippet:

    // Get global point (WGS84 coordinates)
    GlobalPoint? globalPoint = position.point;
    if (globalPoint != null) {
      _demonstrateGlobalPointUsage(globalPoint);
    }
