# Back Button

Back button is **default button** on the left side. 

Back button is a default navigation bar button. You can edit the button and change the icon. Back button **can't be deleted** and it will be always on the left side.

As soon as, there will be navigation in the tab, back button will be visible automatically. Similarly, it will be hidden as soon as there won't be any navigation to be done.
