How to change BottomNavigationBarItem icon when selected, Flutter

Just wanna add to the existing answers: Although `fixedColor`, `(un)selectedItemColor` are the ways to go, there is a gotcha:

They will be overriden by `BottomNavigationBarItem.icon.color`!

So make sure you get rid of the hardcoded icon color first.

BottomNavigationBarItem(
activeIcon: Image.asset(
'lib/assets/images/homeActive.png',
height: 25,
width: 25,
),
icon: Image.asset(
'lib/assets/images/homePassive.png',
height: 25,
width: 25,
),
label: 'Home'
)
