          ),
        ),
      ),

I want like this button

but is becoming like this.

>Solution :

Try below code, used Opacity widget and set opacity:0

Note: Don’t used FlatButton its depricated by Flutter used instead of ElevatedButton, TextButton

Refer here to new buttons

  ElevatedButton(
        onPressed: () {
          //write your onPressed function here
          print('Pressed');
        },
        child: Row(
          mainAxisAlignment: MainAxisAlignment.spaceBetween,
          children: [
            Opacity(
              opacity: 0,
              child: Icon(Icons.arrow_forward),
            ),
            Text('Next'),
            Icon(Icons.arrow_forward),
          ],
        ),
      ),

Your result screen->
