of static method

从最近的 TxRadioTheme 祖先返回配置 data

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

Implementation

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