],

我正在编写 Navigator.push ，如下所示:但是在这里，我想要一些动态的东西.我希望你明白了.

I'm writing the Navigator.push something like below: but here I want to something dynamic. I hope u got it.

onTap(){
Navigator.push(context, MaterialPageRoute(builder: (context)=>CategoryOne(),),);
}

推荐答案

如果每种可能性都具有类别小部件，则可以在MaterialPageRoute构建器中进行切换:

If you have a Category Widget for each possibility then you can a Switch inside the MaterialPageRoute builder:

Navigator.push(context, MaterialPageRoute(builder: (context) {
  switch (selectedCategory) {
    case 'Category One':
      return CategoryOne();
    break;
    case 'Category Two':
      return CategoryTwo();
    break;
    case 'Category Three':
      return CategoryThree();
      break;

    default:
      return CategoryOne();
  }
}));
