Giving the ability to hide the tab bar on page switch. There might be an instance where someone would like to use the full real estate of the screen or prevent a tab switch for a particular case.
I need that feature too.
The use case is when the user enables a switch (I am speaking about an on / off radio style control), one of the tab bar must be hidden. And then, when he disables it again, the tab is shown.
It’s an interesting use case. Please submit a feature request on GitHub for this.
FYI : Seems you already have an open feature request. Just posting it here for others:
