bool locationDataUpdated({ required double latitude, required double longitude, double? lastLatitude, double? lastLongitude, })

Function called when new location data is available. @param latitude The new latitude. @param longitude The new longitude. @param lastLatitude The last latitude seen by MBAutomation. @param lastLongitude The last longitude seen by MBAutomation. @returns If this trigger has changed.
