Navigating to a new page with button class - flutter

Question

This is my buttons class. I want to use its on pressed function to navigate to another page.
class DigerButtonu extends StatelessWidget {
final String butonyazisi;
final IconData butoniconu;
final Function butonfonksiyonu;
const DigerButtonu(this.butonyazisi,this.butonfonksiyonu,this.butoniconu);
#override
Widget build(BuildContext context) {
return Container(
margin: const EdgeInsets.only(left: 20,right: 20),
width: 50,
height: 550,
decoration: BoxDecoration(
boxShadow: [
BoxShadow(
color: Color(0xFF15182D).withOpacity(0.4),
blurRadius: 8,
spreadRadius: 2,
offset: Offset(4,4),
),
],
borderRadius: BorderRadius.all(Radius.circular(10)),
border: Border.all(
color: Colors.black,
width: 0.2,
)
),
child: ElevatedButton(
child: Column(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Icon(butoniconu, color: Colors.white,size: 22,),
MyVerticalText(butonyazisi),
Icon(butoniconu, color: Colors.white,size: 22,),
],
),
style: ElevatedButton.styleFrom(
primary: Color(0xFF15182D),
onPrimary: Colors.white,
onSurface: Colors.grey,
//elevation: 0,
),
onPressed: (){
butonfonksiyonu;
},
),
);
}
}
But when i try to use the code below, it says 'The argument type 'Future'can't be assigned to the parameter type 'Function' '. How can i use it?
DigerButtonu('AYARLAR',Navigator.push(context,MaterialPageRoute(builder: (context) => clicker()), route),Icons.settings_rounded)

Answer 1

You can simply use lambdas for passing functions. Currently you pass the result of your method and not the method itself.
Here is your code with the corresponding lambda expression:
DigerButtonu('AYARLAR', () => Navigator.push(context,MaterialPageRoute(builder: (context) => clicker()), route),Icons.settings_rounded)
