Methods

centerFromLatLngBounds(GoogleMapsUtilsLatLngBounds bounds) → Point<double>

Returns the center point of the given bounds.

computeAngleBetween(Point<double> from, Point<double> to) → double

Returns the angle between from and to, in radians.

computeArea(List<Point<double>> path) → double

Returns the area enclosed by path, in square meters.

computeDistanceBetween(Point<double> from, Point<double> to) → double

Returns the distance between from and to, in meters.

computeHeading(Point<double> from, Point<double> to) → double

Returns the heading from from to to in degrees [-180, 180).

computeLength(List<Point<double>> path) → double

Returns the length of the given path, in meters.

computeOffset(Point<double> from, double distance, double heading) → Point<double>

Returns the point at distance meters from from along heading.

computeOffsetOrigin(Point<double> to, double distance, double heading) → Point<double>?

Returns the origin given a destination to, distance, and heading.

computeSignedArea(List<Point<double>> path) → double

Returns the signed area of path (positive = counter-clockwise).

distanceRadians(double lat1, double lng1, double lat2, double lng2) → double

Returns distance on the unit sphere (radians in, radians out).

getCardinal(double angle) → String

Returns a 16-point compass cardinal abbreviation for the given angle.

interpolate(Point<double> from, Point<double> to, double fraction) → Point<double>

Returns the point at fraction of the way between from and to.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

Creates a bounding box centered at (x, y) with radiusInMeters.

toBoundsFromPoints(List<Point<double>> points) → GoogleMapsUtilsLatLngBounds

Computes the smallest bounding box that contains all points.

toDegrees(double rad) → double

Converts rad radians to degrees.
