As the dev doc says, Dart doesn't have the keywords public, protected, and private. If an identifier starts with an underscore (_), it's private to its library.

But I found many @protected
keywords in Flutter framework. What does the @protected
mean?
abstract class InheritedWidget extends ProxyWidget {
const InheritedWidget({ Key key, Widget child })
: super(key: key, child: child);
@override
InheritedElement createElement() => InheritedElement(this);
@protected
bool updateShouldNotify(covariant InheritedWidget oldWidget);
}
It's used to provide a hint when members are used outside of subclasses, by the Dart Analyzer.
