TxExpansionPanelThemeData class

与 TxExpansionPanelTheme 一起用于定义后代 TxExpansionPanel 小组件的默认属性值。

后代小组件使用“TxExpansionPanelTheme.of（context）”获取当前 TxExpansionPanelThemeData 对象。可以使用 TxExpansionPanelThemeData.copyWith 自定义 TxExpansionPanelThemeData 的实例。

TxExpansionPanelThemeData 通常使用 ThemeData.extensions 指定为整体 Theme 的一部分。

默认情况下，所有 TxExpansionPanelThemeData 属性都为“null”。当主题属性为 null 时， TxExpansionPanel 将根据整体 Theme 的 textTheme 和 colorScheme 提供自己的默认值。 有关详细信息，请参阅各个 TxExpansionPanel 属性。
