I am new to Flutter. I have a BottomNavigationBar
with 4 items. I want to change icon of the item when pressed. Please help.
This is what I have done so far.
bottomNavigationBar : new BottomNavigationBar(
currentIndex: index,
onTap: (int index) {
setState(() {
this.index = index;
}
);
_navigateToScreens(index);
},
type: BottomNavigationBarType.fixed,
items: [
new BottomNavigationBarItem(
backgroundColor: Colors.white,
icon: new Image.asset('images/1.0x/icon1.png'),
title: new Text("Route1", style: new TextStyle(
color: const Color(0xFF06244e), fontSize: 14.0))),
new BottomNavigationBarItem(
icon: new Image.asset('images/1.0x/icon2.png'),
title: new Text("Route2", style: new TextStyle(
color: const Color(0xFF06244e), fontSize: 14.0))),
new BottomNavigationBarItem(
icon: new Image.asset('images/1.0x/icon3.png'),
title: new Text("Route3", style: new TextStyle(
color: const Color(0xFF06244e), fontSize: 14.0),)),
new BottomNavigationBarItem(
icon: new Image.asset('images/1.0x/icon4.png'),
title: new Text("Route4", style: new TextStyle(
color: const Color(0xFF06244e), fontSize: 14.0),))
]);
There is new feature added in flutter in BottomNavigationBarItem that is active icon
. we can use it to tell what should be the icon when a tab is active
bottomNavigationBar : new BottomNavigationBar(
currentIndex: index,
onTap: (int index) {
setState(() {
this.index = index;
}
);
_navigateToScreens(index);
},
type: BottomNavigationBarType.fixed,
items: [
new BottomNavigationBarItem(
backgroundColor: Colors.white,
icon: new Image.asset('images/1.0x/icon1.png'),
activeIcon:new Image.asset('images/1.0x/newIcon.png'),
title: new Text("Route1", style: new TextStyle(
color: const Color(0xFF06244e), fontSize: 14.0))),
new BottomNavigationBarItem(
icon: new Image.asset('images/1.0x/icon2.png'),
activeIcon:new Image.asset('images/1.0x/newIcon.png'),
title: new Text("Route2", style: new TextStyle(
color: const Color(0xFF06244e), fontSize: 14.0))),
new BottomNavigationBarItem(
icon: new Image.asset('images/1.0x/icon3.png'),
activeIcon: new Image.asset('images/1.0x/newIcon.png'),
title: new Text("Route3", style: new TextStyle(
color: const Color(0xFF06244e), fontSize: 14.0),)),
new BottomNavigationBarItem(
icon: new Image.asset('images/1.0x/icon4.png'),
activeIcon: new Image.asset('images/1.0x/newIcon.png'),
title: new Text("Route4", style: new TextStyle(
color: const Color(0xFF06244e), fontSize: 14.0),))
]),
Hope someone will find this useful.
