video_player plugin: 0.6.4 - Future already completed #19197
Description
I upgraded to this version of the plugin and on iOS on an iPhone 8+ I am getting:
[ +391 ms] [VERBOSE-2:dart_error.cc(16)] Unhandled exception:
[ ] Bad state: Future already completed

I don't see any particular problems, but my customer on his iPhone 6 cannot see the streaming video until the first redraw of the video player (e.g. turning it landscape). I need the video to start playing as soon a possible, but this does not seem to affect this exception, it is always thrown. the initState method is:
_controller = new VideoPlayerController.network(
event.cameras[0].url,
)
..addListener(() {
final bool isPlaying = _controller.value.isPlaying;
if (isPlaying != _isPlaying) {
setState(() {
_isPlaying = isPlaying;
});
}
if (_controller.value.hasError) {
print("error: ${_controller.value.errorDescription}");
}
})
..initialize().then((_) {
setState(() {
_controller.play();
});
});and the video player creation is straight from the example.
