Hello everyone!

I have a little problem, I want to link each icon of my bottom bar to a different screen. The problem is that if I link it the fact that when  you click on the icon and it changes the color because it is "selected" disappears. So can you tell me or show me how to do it? To resume, I want to link each icon to a screen, so when you click on the icon the color changes and stay darker and you are on the right screen. I have put a file that you can modify, if you can show me.

I have already tried to add a link on each icon, around the container... everywhere. I have also tried to put redirection on the client action that goes to the right screen. 

Thank you for your help,

Marianig
