Enable more platforms

[kawa89]

1. Check what is blocking the support
2. Remove blocking packages and add support for new ones.
3. Try to enable support for:
   • Web
   • Mac
   • Windows

When it comes to blocking packages I can see 2.

cached_network_image

This one is tricky. On pub.dev it says that package supports android, ios and mac. It is also written that it has minimal support for web. I don't see any info about Linux or Windows. When I was searching Issues I found this - Baseflow/flutter_cached_network_image#707 - it says that Windows should actually be supported. Also according to this Baseflow/flutter_cached_network_image#661 - it should also be supported on Linux.

So it turns out this package is supported on all the platforms but because of some problems described in Baseflow/flutter_cached_network_image#661 it is not marked like this in pub.dev. So potential problem might be that our package would also not mark proper platforms as supported.

better_player

So this package is only supported on Android and iOS.

Web

One of the solution would be to replace better_player with video_player that has support for web (through federated package). The problem would remain with desktops.

I can see an open issue for adding support for Windows - flutter/flutter#37673

Desktop

One option would be to use dart_vlc package. It supports iOS, Linux, MacOS and Windows. We could also do something like for one platform use video_player and for others dart_vlc plugin.

would love windows support. it's helpful to develop apps on windows even if that run later mostly on android. it speeds up development.
