NoSuchMethodError: The getter 'inMicroseconds' was called on null.

[Risen-Solutions]

This is probably a stupidly simple QUESTION but I am pulling my hair out trying to work out what is going on. I'm trying to follow the remote url example, calling the playerWidget.dart file (exactly the same as the example) passing a url as the only parameter. I can see, via debug, that the url is passing correctly; however I am getting the error noted below.

When I followed it through to the audioplayers.dart file I can see that the example has different code to the 0.8.0 in lines 107-108... however I am too much a newbie to be able to fix that problem! :-(

Example (107-108)
{bool isLocal: false, double volume: 1.0, Duration position}) async {
final double positionInSeconds = position == null ? null : position.inSeconds.toDouble();

0.8.0 (107-108)
{bool isLocal: false, double volume: 1.0, Duration position: Duration.zero}) async {
double positionInSeconds = position.inMicroseconds / Duration.microsecondsPerSecond;

Any thoughts on how to correct this error? As noted, I am sure that it is a simple issue...

Thanks for reporting this, this is supposed to be already fixed on master, we just need to run some tests and release the new version.

Sorry for the problems, I will let you know when the version is released, we may do this on the middle of this week.
