of static method

从最近的 TxStatusIndicatorTheme 祖先返回配置 data

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

Implementation

static TxStatusIndicatorThemeData of(BuildContext context) {
  final TxStatusIndicatorTheme? radioTheme =
      context.dependOnInheritedWidgetOfExactType<TxStatusIndicatorTheme>();
  return radioTheme?.data ??
      Theme.of(context).extension<TxStatusIndicatorThemeData>() ??
      const TxStatusIndicatorThemeData();
}
