This library is a RelativeLayout, therefore you can use the public boolean isShown() method from View :

To hide the button if it's shown, and then close the activity, do as follow :

@Override
public void onBackPressed() {
    if (fabToolbar.isToolbar()) {
        fabToolbar.hide();
    }
    super.onBackPressed();
}

However, if you want your back button to behave as Is Fab showing? If so hide it, otherwise close the activity Then have the following : 

@Override
public void onBackPressed() {
    if (fabToolbar.isToolbar()) {
        fabToolbar.hide();
    } else 
      super.onBackPressed();
    }
}

EDIT : N J is correct, the library uses isToolbar() to store the visibility.

If you look properly in library isToolbar()

isToolbar() return true if ToolBar is visible else it will return false

public boolean isToolbar() {
    return isToolbar;
}

EDIT

if (fabToolbar.isToolbar()) {
        fabToolbar.hide();
    } else 
      super.onBackPressed();
    }

its must be fabToolbar.isShown() and super.onBackPressed() when you use inside

@Override
public void onBackPressed() {
    if (fabToolbar.isShown()) {
        fabToolbar.hide();
    } else {
        super.onBackPressed();
    }
}
