声明同一类的多个对象？

Question

有没有更好的方式编写此代码：

  TextEditingController ectrl = TextEditingController();
  TextEditingController passctrl = TextEditingController();
  TextEditingController fnamectrl = TextEditingController();
  TextEditingController lnamectrl = TextEditingController();

我的意思是快来吧！

Answer 1

    var ectrl = TextEditingController(),
        passctrl = TextEditingController(),
        fnamectrl = TextEditingController(),
        lnamectrl = TextEditingController();

    var ctrls = List.generate(4, (index) => TextEditingController());
