Every time I try to instantiate an instance of LatLng using the constructor, I get
"Invalid argument(s): Longitude must be between -90 and 90 degrees but was -180.00001532690865"

Regardless of the arguments I pass in. Even LatLng(0,0) will return this error.

Isn't this supposed to be:

- String lonDirection = longitude >= 0 ? "O" : "W"; 
+ String lonDirection = longitude >= 0 ? "E" : "W"; 

When dec is 53.0335 then splitting a double into two parts, that then get parsed as integers is wrong!

The fractionalPart 0335 becomes an integer - 335, and then "recreating" a double by doing 0.$fractionalPart is simply silly.

0.335 != 0.0335

final String sexa2 = decimal2sexagesimal(-42.883891);
expect(sexa2, '42° 53\' 02.01"'); // got '42° 53\' 20.08"'

The right way of doing this is:

/// Converts a decimal coordinate value to sexagesimal format
///
///     final String sexa1 = decimal2sexagesimal(51.519475);
///     expect(sexa1, '51° 31\' 10.11"');
///
///     final String sexa2 = decimal2sexagesimal(-42.883891);
///     expect(sexa2, '42° 53\' 02.01"');
///
String decimal2sexagesimal(final double dec) {
  if (dec == null) throw new ArgumentError.notNull('dec');

  final buf = new StringBuffer();

  final double absDec = dec.abs();
  final int deg = absDec.floor();
  buf.write(deg.toString() + '°');

  final double mins = (absDec - deg) * 60.0;
  final int min = mins.round();
  buf.write(' ' + zeroPad(min) + "'");

  final double secs = (mins - mins.floorToDouble()) * 60.0;
  final int sec = secs.round();
  final int frac = ((secs - secs.floorToDouble()) * 100.0).round();
  buf.write(' ' + zeroPad(sec) + '.' + zeroPad(frac) + '"');

  return buf.toString();
}

/// Pads a number with a single zero, if it is less than 10
String zeroPad(num number) => (number < 10 ? '0' : '') + number.toString();

Sorry, I'm calling this function a lot, so StringBuffer makes sense for me.

Hello, thanks for this package.

Would a function to calculate the angle between two Latitude/Longitude points be of interest for this package? If so, I'll work on a pull request for such a feature.

Hi Creators,

Thanks for the great plugin. This is the easiest and very straight forward plugin I ever used to calculate LatLng distance. But I'v a small doubt.

In Circle constructor,

Circle(LatLng center, double radius, { DistanceCalculator calculator: const Vincenty() })

The radius indicates what unit meters or kilometers, something else? I went through the documentation regarding this but I couldn't able to find it. If I know the correct unit, so then I can draw a circle in the map.

I am trying to build a custom clipper class which uses for instance Path.lineTo()but the compiler is not accepting it because I am also using latlong.dart and it has a class named Path. Am I doing something wrong? Thanks Mike

Hi @MikeMitterer,
The library version 6.0.1 doesn't work with dart 2,
error mesage

The current Dart SDK version is 2.1.0-dev.0.0.flutter-be6309690f.

Because project depends on latlong >=0.1.1 <0.6.1 which requires SDK version >=1.8.0 <2.0.0, version solving failed.
