替换颤振中已弃用的 textTheme

如何解决替换颤振中已弃用的 textTheme

我是 Flutter 的新手，仍然熟悉它的术语和属性。无论如何，当我使用 textTheme 并提及 title、button 等任何属性时，它表明该属性已被弃用，不应再使用。我的假设是 textTheme 仅被弃用，那么我应该用什么替换它，以便它不被弃用？

解决方法

对于 title，您需要改用 subtitle1。

您可以在 text _theme.dart 中查看来自 TextTheme 源代码的弃用列表。如果您使用的是 IntelliJ，则可以通过右键单击 title 属性查看源代码，然后选择转到 -> 声明或用法。

此处是 text _theme.dart 已弃用属性的摘录：
