of static method

TxExpandableTextThemeData of(
  1. BuildContext context
)

从最近的 TxExpandableTextTheme 祖先返回配置 data。

如果没有祖先，则返回 ThemeData.extension<TxExpandableTextThemeData>()。 如果它也为null，则返回默认TxExpandableTextThemeData

Implementation

static TxExpandableTextThemeData of(BuildContext context) {
  final TxExpandableTextTheme? expandableTextTheme =
      context.dependOnInheritedWidgetOfExactType<TxExpandableTextTheme>();
  return expandableTextTheme?.data ??
      Theme.of(context).extension<TxExpandableTextThemeData>() ??
      const TxExpandableTextThemeData();
}
