Sometime we need bigger components for our app. Default sizes are not enough. If you check the Checkbox API. It doesn’t have any api to set width and height property. I don’t have any idea why they did this. But we can do a workaournd for this using TRANSFORM widget.

Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Transform.scale(
scale: 3.0,
child: Checkbox(
activeColor: Colors.orange,
shape: CircleBorder(),
tristate: false,
value: true,
splashRadius: 30,
onChanged: (bool value) {
}
),
)
],
)

you can see the size is big now
