What's the command in minecraft for flying?

I want to familiarize myself with the command blocks and would like to insert fly. What's the name of the command? I play on the switch. I'm looking forward to an answer.

If you mean in Singelplayer then that goes with / gamemode 1.

On some servers this works with / fly, but you need certain rights for this…

In Singelplayer you can fly as already said in Gamemode1 by double-clicking on the button with which you jump.

The command is called

/ gamemode creative

But if you want to do it all in a Commandblock you have to

gamemode creative @p

enter. Or, instead of the @p (= player closest to you), enter the player name directly:

gamemode creative Name of the player

Alternatively, instead of "creative" of course also "spectator", depending on the application.

I do not want to play in creative mode but just fly skills and play in survival

That will not do. There's no such a command.

OK
