Dart中implements实现多个接口

abstract class A{
  String name;
  printA();
}

abstract class B{
  printB();
}

class C implements A,B{  
  @override
  String name;  
  @override
  printA() {
    print('printA');
  }
  @override
  printB() {
    // TODO: implement printB
    return null;
  }

  
}


void main(){

  C c=new C();
  c.printA();


}
