单击按钮时，我试图获取要导航到的屏幕名称（在自定义类中）。

class myButton extends StatelessWidget {
  String button_txt = '';
  String nextPage = '';
  double height_ = 39;

  myButton(button_txt) {
    this.button_txt = button_txt;
    this.nextPage = nextPage;
  }
  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        Navigator.pushReplacement(context, '/$nextPage');
      },
