Methods

calculateBestCenter({required Set<TLocationComponents> locations, required double threshold, required DistanceUnit distanceUnit}) → TLocationComponents

Available on LocationUtils, provided by the CalculateBestCentereOnLocationPackageExtension extension

Calculates the best center for a set of locations. This is the geometric center unless the distance to the closest marker is greater than the threshold, then the closest marker is used. The distanceUnit is the unit of the threshold.

calculateGeometricCenter(Set<TLocationComponents> locations) → TLocationComponents

Available on LocationUtils, provided by the CalculateGeometricCentereOnLocationPackageExtension extension

Calculates the geometric center of a set of locations.

calculateHavershire3DDistance({required TLocationComponents location1, required TLocationComponents location2, DistanceUnit unit = DistanceUnit.METRES, CelestialRadius radius = CelestialRadius.EARTH}) → double

Available on LocationUtils, provided by the CalculateHavershire3DDistanceOnLocationPackageExtension extension

Calculate the distance between two locations using the Haversine formula and optionally the elevation difference.

calculateZoomToFit(Iterable<TLocationComponents> locations, {double factor = 1.0, double minZoom = 10.0, double maxZoom = 20.0}) → double

Available on LocationUtils, provided by the CalculateZoomToFitOnLocationPackageExtension extension

Calculates the zoom level to fit all the locations on a map. The factor is a multiplier to adjust the zoom level. The minZoom and maxZoom are the minimum and maximum zoom levels to clamp the result.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

toString() → String

A string representation of this object.
