play called on null

[logemann]

I am geting this when try running the example:

The method 'play' was called on null.
Receiver: null
Tried calling: play()

after digging some more. Here is the debug screenshot. There is an issue in _fetchVideoURL().

parseAll = _allStringMatches(urls[1], RegExp("([^&,]*)[&,]"));

fails with the URL:

And thus videoController is not getting initialized and then play is called on null. There should be an error way before hitting the play button.

My Playlist is:

  final List<String> playlist = <String>[
    'https://www.youtube.com/watch?v=xLNeZogTsK8',
  ];

I experience the same problem. Seems to me that YouTube changed something so it affected everyone who tries to download their videos. Check this for example kkdai/youtube#14

I've got the same issue.

I get this before the error.
E/flutter (16585): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: RangeError (index): Invalid value: Valid value range is empty: 0

then,

The method 'play' was called on null.
I/flutter (16585): Receiver: null
I/flutter (16585): Tried calling: play()
