                icon: Icon(Icons.sentiment_very_satisfied),
              ),
              RaisedButton(

>Solution :

ElevatedButton don’t have exact same property as RaisedButton had.
But you can do everything which you were doing with RaisedButton like below

ElevatedButton(
        onPressed: () {
          _handleSignIn();
        },
       //Styles contains all the design related to button
        style: ButtonStyle(
          backgroundColor: MaterialStatePropertyAll(Colors.blue),
        ),
        //Child is basically what you want to display inside button It can be Text, Row, Column, or Icon.
        child: Row(
          children: const [
            Text("Google Giris Yap", style: TextStyle(color: Colors.white),),
            Icon(Icons.sentiment_very_satisfied),
          ],
        ),
      )
