Here is a straightforward example demonstrating the usage of a map library:
<!doctype html>
<html>
<head>
<script src="http://api4.mapy.cz/loader.js"></script>
<script>Loader.load()</script>
</head;
<body>
<div id="mapa" style="width:600px; height:400px;"></div>
<script type="text/javascript">
var center = SMap.Coords.fromWGS84(14.41, 50.08);
var map = new SMap(JAK.gel("mapa"), center, 10);
mapa.addDefaultLayer(SMap.DEF_BASE).enable();
mapa.addDefaultControls();
</script>
</body>
</html>
I am looking for ways to integrate this code into Dart without relying on JavaScript as I lack expertise in that language. Despite trying options like GWT and experimenting with Dart, integrating third-party libraries has been challenging. For instance, my attempted Dart implementation looks like this:
var center = context['SMap']['Coords'].callMethod('fromWGS84', [14.41, 50.08]);
var element = context['JAK'].callMethod('gel', 'mapa');
var map = new JsObject(context['SMap'],[[element], [center], 10]);
While the first line seems promising, further progress is halted by undefined errors and typical JavaScript confusion. Debugging dart.js feels like delving into a realm of pure chaos.
