InheritedWidget章节中，应该是返回true则依赖本控件data的子树会执行didChangeDependencies()回调，原文是false
原文：

  //该回调决定当data发生变化时，是否通知子树中依赖data的Widget  
  @override
  bool updateShouldNotify(ShareDataWidget old) {
    //如果返回false，则子树中依赖(build函数中有调用)本widget
    //的子widget的`state.didChangeDependencies`会被调用
    return old.data != data;
  }
