Utilize DMS (degree-minutes-seconds) formatting by geobase 0.5.1

[navispatial]

geobase 0.5.1 has support for spherical geodesy functions and also DMS formatting utilities.

See sample from geobase:

Format geographic coordinates as string representations (DD, DM, DMS):

```dart
  const p = Geographic(lat: 51.4778, lon: -0.0014);

  // all three samples print decimal degrees: 51.4778°N 0.0014°W
  print(p.latLonDms(separator: ' '));
  print('${p.latDms()} ${p.lonDms()}');
  print('${Dms().lat(51.4778)} ${Dms().lon(-0.0014)}');

  // prints degrees and minutes: 51°28.668′N, 0°00.084′W
  const dm = Dms(type: DmsType.degMin, decimals: 3);
  print(p.latLonDms(format: dm));

  // prints degrees, minutes and seconds: 51° 28′ 40″ N, 0° 00′ 05″ W
  const dms = Dms.narrowSpace(type: DmsType.degMinSec);
  print(p.latLonDms(format: dms));

  // 51 degrees 28 minutes 40 seconds to N, 0 degrees 0 minutes 5 seconds to W
  const dmsTextual = Dms(
    type: DmsType.degMinSec,
    separator: ' ',
    decimals: 0,
    zeroPadMinSec: false,
    degree: ' degrees',
    prime: ' minutes',
    doublePrime: ' seconds to',
  );
  print(p.latLonDms(format: dmsTextual));

Parsing and formatting is supported also for geographic bounding boxes:

  // Parses box from decimal degrees (DD) with cardinal direction symbols.
  final box =
      GeoBox.parseDms(west: '20°W', south: '50°N', east: '20°E', north: '60°N');

  // prints degrees and minutes: 20°0′W 50°0′N, 20°0′E 60°0′N
  const dm0 = Dms(type: DmsType.degMin, decimals: 0, zeroPadMinSec: false);
  print('${box.westDms(dm0)} ${box.southDms(dm0)}'
      ' ${box.eastDms(dm0)} ${box.northDms(dm0)}');

In the previous example dm, dm0, dms and dmsTextual are instances of the
Dms class that implements DmsFormat. This defines multiple methods for
parsing and formatting decimal degrees and sexagesimal degrees
(degrees/minutes/seconds) on latitude, longitude and bearing values.

The default format used by Geographic and GeoBox classes formats values as
decimal degrees with cardinal direction symbols. To use other formats
(degrees/minutes or degrees/minutes/seconds), or to set other parameters (like
separators, symbol characters, the number of decimals, zero padding or value
signing) you should create a custom Dms instance.

Utilizing these utilities when representing geographic coordinates in UI.
