如何知道哪些主题数据在 Flutter 中改变了什么

Question

在 Flutter 中，很难找出哪些主题属性改变了应用程序的哪个部分。例如，AppBar 的背景颜色默认为正在使用的主题的primaryColor。我没有在 AppBar 的文档中的任何地方看到这个

https://docs.flutter.io/flutter/material/AppBar-class.html

我们应该如何知道哪个主题属性会改变我们小部件的哪些部分？

这不是一个很好的答案，但在 3 1/2 年后，这个优秀的问题仍然没有更好的答案：

如果您仍在搜索 - 请查看 Vivek Yadav 的这篇精彩指南 - 在他的文章中，他详细介绍了每个 ThemeData 参数：
