Changing Text Color onTap, Flutter - ios

Question

I am an android developer new to flutter and i am trying to create 3 grey text widgets where when a user clicks one, the clicked one becomes blue while the others remain grey. This is the code i currently have
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: const <Widget>[
InkWell(
child: Text('Click 3',
style: TextStyle(
color: Colors.indigo,
fontSize: 15.0,
fontWeight: FontWeight.bold,
)),
onTap: () => Colors.blue,
),
InkWell(
child: Text('Click 2',
style: TextStyle(
color: Colors.indigo,
fontSize: 15.0,
fontWeight: FontWeight.bold,
)),
onTap: () => Colors.blue,
),
InkWell(
child: Text('Click 3',
style: TextStyle(
color: Colors.indigo,
fontSize: 15.0,
fontWeight: FontWeight.bold,
)),
onTap: () => Colors.blue,
),
],
),
Also whatever i put in onTap() i get the error that says
invalid constant value

Answer 1

You should create three separate variables for each button's color and then remove the const keyword in Row,
Color firstColor = Colors.indigo;
Color secondColor = Colors.indigo;
Color thirdColor = Colors.indigo;
...
Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: <Widget>[ /// remove const keyword
InkWell(
child: Text('Click 3',
style: TextStyle(
color: firstColor,
fontSize: 15.0,
fontWeight: FontWeight.bold,
),
),
onTap: (){
setState((){
firstColor=Colors.blue;
});
},
),
InkWell(
child: Text('Click 2',
style: TextStyle(
color: secondColor,
fontSize: 15.0,
fontWeight: FontWeight.bold,
),
),
onTap: (){
setState((){
secondColor=Colors.blue;
});
},
),
InkWell(
child: Text('Click 3',
style: TextStyle(
color: thirdButton,
fontSize: 15.0,
fontWeight: FontWeight.bold,
),
),
onTap: (){
setState((){
thirdColor=Colors.blue;
});
},
),
],
),
