You should be using FloatingActionButton instead, however if you still want to use Button then make use of the below code:

ElevatedButton(
  onPressed: (){},
  style: ElevatedButton.styleFrom(
  shape: const CircleBorder(),
  primary: Colors.lightGreen,
  fixedSize: const Size(60,60)
         ),
  child: const Icon(Icons.add_circle_outline))

You can use Floating action button for that : https://api.flutter.dev/flutter/material/FloatingActionButton-class.html

Solution 3:^[3]

I recommend to use FloatingActionButton instead of TextButton:

FloatingActionButton(
                 onPressed: (){},
                 child: Icon(Icons.add),
               ),

your code should be like:

Padding(
                    padding: const EdgeInsets.fromLTRB(300, 150, 0, 0),
                    child: SizedBox(
                      height: 50,
                      child: FloatingActionButton(
                 onPressed: (){},
                 child: Icon(Icons.add),
                      ),
                    ),
                  ),

You can use a FloatingActionButton

Like so:

FloatingActionButton(
  child: Icon(Icons.add_circle_outline),
  backgroundColor: Color(0xffCAEC93),
  onPressed: (){
   //do something
  }
)

Use Container and give border radius to container and wrap conatiner widget with InkWell.

Center(
        child: InkWell(
          onTap: (){
            print("Clicked");
          },
          child: Container(
            alignment: Alignment.center,
            height: 106,
            width: 106,
            decoration: BoxDecoration(
              color: Colors.white,
              borderRadius: BorderRadius.all(Radius.circular(80)),
            ),
            child: Image.asset("assets/edit.png",scale: 8,)
          ),
        ),
      ),
