Identical to Remi’s declaration, there is a VoidCallback typedef already declared in Flutter.
So you could just declare it as:
VoidCallback onPress;
However, if you want to pass in parameters, you should setup your own typedefs.

class Human {
void Function() onPress;
Human({

}
or
typedef VoidFunction = void Function();

VoidFunction onPress;
Human({

VoidCallback onPress works but you can also use Function onPress too like this
class Human {
Function onPress;
Human({
this.onPress,
});
}
