void main() {
  // `GeoCoordinate` names the pair, because a swapped latitude and longitude is a type bug no range
  // check catches. ISO 6709 picks the unit by field width, and all three widths fold to degrees.

  print(GeoCoordinate.tryParse('[phone]/')?.latitude); // 50.2  (degrees and minutes)
  print(GeoCoordinate.tryParse('+46+2/')); // null (an unpadded longitude is a different location)
