The Web platform does not suppport dart:io, so attempts to create a VideoPlayerController.file will throw an UnimplementedError.
Autoplay
Playing videos without prior interaction with the site might be prohibited
by the browser and lead to runtime errors. See also: https://goo.gl/xX8pDD.
Supported Formats
Different web browsers support different sets of video codecs.
Video codecs?
Check MDN's Web video codec guide to learn more about the pros and cons of each video codec.
What codecs are supported?
Visit caniuse.com: 'video format' for a breakdown of which browsers support what codecs. You can customize charts there for the users of your particular website(s).
Here's an abridged version of the data from caniuse, for a Global audience:
MPEG-4/H.264
WebM
Ogg/Theora
AV1
HEVC/H.265
