if you want to call printSample() func you can use:

class Myapp extends StatefulWidget{
...
    MyappState myAppState=new MyappState();
    @override
    MyappState createState() => myAppState;
    void printSample(){
        myAppState.printSample();
    }
}
class MyAppState extends State<MyApp>{
    void printSample (){
        print("Sample text");
    }
}

...............
Myapp _myapp = new Myapp();
myapp.printSample();
...
