How to use MaterialStateTextStyle?

问题

Flutter已经放弃了它的易用性,尤其是对于TextButtons。

我想要一个透明的TextButton,文本颜色为红色。我该如何在这里实现,你能解释一下为什么以及如何在这里使用MaterialStateTextStyle吗?

TextButton.icon(
    style: ButtonStyle(
        backgroundColor: MaterialStateProperty.all<Color>(Colors.transparent),
        textStyle: MaterialStateTextStyle(color: Colors.red) // 错误
    ),
    onPressed: () {},
    icon: Icon(Icons.search),
    label: Text('Search'),
);

Flutter has abandonded its easy applicability, in particular for TextButtons.

I would like to have a transparent TextButton with a red text color. How do I implement that here and could you explain, why and how you use MaterialStateTextStyle here?

TextButton.icon(
    style: ButtonStyle(
              backgroundColor: MaterialStateProperty.all&lt;Color&gt;(Colors.transparent),
              textStyle:  MaterialStateTextStyle(color : Colors.red) // wrong
                        ),
                        onPressed: () {},
                        icon: Icon(Icons.search),
                        label: Text(&#39;Search&#39;),
                      );

你可以使用 Text 和 Icon 的参数来添加颜色,就像这样:

TextButton.icon(
      style: ButtonStyle(
        backgroundColor:
            MaterialStateProperty.all<Color>(Colors.transparent),
      ),
      onPressed: () {},
      icon: Icon(
        Icons.search,
        color: Colors.red,
      ),
      label: Text(
        'Search',
        style: TextStyle(color: Colors.red),
      ),
    );
英文:

You can add color using parameter in Text and Icon like this:

TextButton.icon(
      style: ButtonStyle(
        backgroundColor:
            MaterialStateProperty.all&lt;Color&gt;(Colors.transparent),
      ),
      onPressed: () {},
      icon: Icon(
        Icons.search,
        color: Colors.red,
      ),
      label: Text(
        &#39;Search&#39;,
        style: TextStyle(color: Colors.red),
      ),
    );
