Dart utility methods to convert a gps coordinate to Cardinal

main.dart

void main() {
  
  Map<String,dynamic> toDegreesMinutesAndSeconds(double coord) {
    double absolute = coord.abs();
    int degrees = absolute.floor();
    double minutesNotTruncated = (absolute - degrees) * 60;
    int minutes = minutesNotTruncated.floor();
    double seconds = ( (minutesNotTruncated - minutes) * 60 );
    
    return {
      'degrees':degrees,
      'minutes':minutes,
      'seconds':seconds.toStringAsFixed(0),
    };
  }
  
  Map<String,dynamic> convertDMS(double lat, double long) {
    Map<String,dynamic> latitude = toDegreesMinutesAndSeconds(lat);
    String latCardinal = lat >= 0 ? 'N' : 'S';
    
    Map<String,dynamic> longitude = toDegreesMinutesAndSeconds(long);
    String longCardinal = long >= 0 ? 'E' : 'W';
    
    return {
      'latitudeCardinal': '${latitude['degrees']} ${latitude['minutes']} ${latitude['seconds']} ${latCardinal}',
      'longitudeCardinal': '${longitude['degrees']} ${longitude['minutes']} ${longitude['seconds']} ${longCardinal}',
    };
  }
  
  print(toDegreesMinutesAndSeconds(38.343080));
  print(convertDMS(38.343080,-109.666190));
}

Thanks so much. You saved my time
