 File gpxFile = new File("test/resources/my_favorite_trail.gpx"); 

 gpxFile.readAsString().then((gpxFileContent) {
     traceAnalyser.buildTraceAnalysisFromGpxFileContent(gpxFileContent).then((trace){
 
       print("Trace length: ${trace.length} meters");
       print("Positive elevetion: ${trace.up}");
       print("Highest point elevetion: ${trace.upperPoint.elevetion}");
           
     });
 });


}
