Nothing wrong in the code of this PR. But:

• I do not reproduce Choosing a time from the play button does not apply it to your OTB match. It'll always just start with 5 minutes #2317 , do you?
• this PR is about showing automatically the setup bottom sheet; I don't see how this could fix any issue reported in the above issue?

Yes, I am able to reproduce it. I decided to show the new game bottom sheet so user can decide the time control and variant to play before game start.
I chose this approach to fix the issue as over the board is separated from the widget that contains the create a game button and the buttons are also far apart. This also doesn't cause any coupling between create a game and over the board.

Closing as the issue is not an issue (cf #2317 )

Maybe we want to show the bottom sheet anyways, as it improves the UX.
Currently the players need to open the a bit hidden menu to change the timecontrol except if they want to play 5+3. (Its not even obvious that its +3 at the beginning of the game)

Yes the UX could be improved for sure. I am open to new suggestions, or PRs, if you feel like it. Note that I also don't like the bottom sheet automatically open if it doesn't allow to start the game in one tap. Which was the case if I'm not mistaken. So I'd accept an UX change, but it'd need to be a little better than just this opening of bottom sheet.

It seems like the bottom sheet allows to start the game in one tap:
