我使用React Native 0.16(Android)时遇到了麻烦.问题是如何将props传递给属于组件的Navigator.NavigationBar的routeMapper.<Navigator />

我的代码结构如下

class MyApp extends Component {    
    ...

    static NavigationBarRouteMapper = {
        LeftButton(route, navigator, index, navState) {
            // ### I want to call 'functionABC' here. What Should I do?
        },
        RightButton(route, navigator, index, navState) {
            // ### I want to call 'functionABC' here. What Should I do?
        },            
        Title(route, navigator, index, navState) {
            // ### I want to call 'functionABC' here. What Should I do?
        },           
    }       

    ...

    functionABC() {
       ...
    }      

    ... …
