我是一个初来乍到的新手，对它的术语和特性仍然很熟悉。无论如何，当我使用textTheme，并提到任何属性，如title、button等，都会显示出该属性已经过时，不应该再使用了。我的假设是，textTheme只被弃用，所以我应该用什么来代替它，这样它就不会被废弃了？

对于title，您需要使用subtitle1代替。

您可以在TextTheme源代码中看到text _theme.dart中的不推荐列表。如果您使用的是IntelliJ，您可以通过右键单击title属性查看源代码，然后选择Go To -> 声明或Usage。

这里摘录了text _theme.dart的不推荐属性

不建议使用

textTheme，不应该使用它。此属性不再使用，请改用toolbarTextStyle和titleTextStyle。这个特性在v2.4.0-0.PRE之后就被否决了。溶液

使用toolbarTextStyle

  appBarTheme: AppBarTheme(
      color: Colors.white,
      elevation: 0.0,
      iconTheme: IconThemeData(color: Colors.black),
      toolbarTextStyle: Theme.of(context).textTheme.bodyText2,
      titleTextStyle: Theme.of(context).textTheme.headline6)),
