I didnt getting any splash effect or any other effect when tapping on this button. I add inkwell for different widgets also but its still not working

Answer 1

By checking your code onTap: (){}, is disable but by adding onTap still splash effect is not show so I added one extra Position widget and by this I given splash effect by using Material
InkWell(
onTap: (){},
splashColor: Colors.brown,
child: CircleAvatar(
radius: 40,
backgroundColor: Colors.grey[600],
child: CircleAvatar(
radius: 37,
backgroundColor: Colors.white,
child: Stack(
children: [
Positioned(
top: 4,
left: 4,
bottom: 4,
right: 4,
child: IconButton(
icon: Icon(
Icons.ten_k,
size: 40,
color: Colors.grey[600],
),
onPressed: () {},
),
),
Positioned( // This I'm added
left: 0.0,
top: 0.0,
bottom: 0.0,
right: 0.0,
child: Material(
type: MaterialType.transparency,
child: InkWell(
onTap: () async {
await Future.delayed(
Duration(milliseconds: 200));
},
),
),
),
],
),
),
),
),

Answer 2

Wrap InkWell with the Material widget.
Material(
child: InkWell(
child:...
onTap:(){ //<-- must not be null otherwise it is considered as disabled
}
)
)

Answer 3

you must add onTap parameter to InkWell widget otherwise it will be disabled hence it won't have any effect.
your InkWell widget should be like this:
InkWell(
onTap: () {},
child: CircleAvatar(
radius: 40,
child: ....,
),
),
