I've addressed your comments but removing those two dependency_overrides section results error like this:

Error (Xcode): ../lib/video_player.dart:441:29: Error: Member not found: 'isPlayingStateUpdate'.

iOS part looks good

My understanding is that what you changed is the standard approach in 1p plugins. IIRC I have seen similar practice in other plugins. Without that overrides, the dependency would be the previously published version

[hellohuanlin]

I stamped the iOS part. you probably wanna add back the reviewers for android/web.

[maRci002]

How can add back the reviewers?

[ditman]

The web bits look good to me, this is a big update for the player, thanks for doing it!

[camsim99]

The Android parts look good to me!

This PR made me realize the lack of test coverage on the Android native parts, so you could add a test for this change, but definitely not blocking for this PR. More-so a note to self :)

LGTM

It looks like this also already has approval for, iOS, web, and Android. So, I'll take a look at #3361.

In my opinion this PR is ready

• removed dependency_overrides
• removed // ignore: missing_enum_constant_in_switch which was created by [video_player] add missing_enum_constant_in_switch #3435
• updated video_player_platform_interface dependencies to 6.1.0 since [video_player_platform_interface] synchronize isPlaying state #3361 PR increased the version
