Getting Started

In your dart/flutter project add the dependency:

 dependencies:
   ...
   gpx: ^0.0.1

Reading XML

To read XML input use the GpxReader object and function Gpx fromString(String input):

import 'package:gpx/gpx.dart';

main() {
  // create gpx from xml string
  var xmlGpx = GpxReader().fromString('<?xml version="1.0" encoding="UTF-8"?>'
      '<gpx version="1.1" creator="dart-gpx library">'
      '<wpt lat="-25.7996" lon="-62.8666"><ele>10.0</ele><name>Monte Quemado</name><desc>Argentina</desc></wpt>'
      '</gpx>');

  print(xmlGpx);
  print(xmlGpx.wpts);
}

Writing XML

To write object to XML use the GpxWriter object and function String asString(Gpx gpx, {bool pretty = false}):

import 'package:gpx/gpx.dart';

main() {
  // create gpx object
  var gpx = Gpx();
  gpx.creator = "dart-gpx library";
  gpx.wpts = [
    Wpt(lat: 36.62, lon: 101.77, ele: 10.0, name: 'Xining', desc: 'China'),
  ];

  // generate xml string
  var gpxString = GpxWriter().asString(gpx, pretty: true);
  print(gpxString);
}

Limitations

This is just an initial version of the package. There are still some limitations:

• No support for 'extension' tag.
• No support for GPX 1.0.
• Partly for some tags (wpt.ageofdgpsdata, wpt.geoidheight, wpt.dgpsid, wpt.fix, wpt.sym)
• Read/write only from strings.
• Doesn't validate schema declarations.
