我指的是官方文档的这个页面:https ://wix.github.io/react-native-navigation/#/screen-api?id=listen-to-visibility-events-globally
创建此类后,我如何告诉导航器使用它?

ScreenVisibilityListener
通过 react-native eventDispatcher 监听原生端触发的全局事件,导航器不需要知道。
示例用法:
import {ScreenVisibilityListener} from 'react-native-navigation';
new ScreenVisibilityListener({
willAppear: ({screen}) => {
console.log(`Displaying screen ${screen}`)
},
didAppear: ({screen, startTime, endTime, commandType}) => {
console.log('screenVisibility', `Screen ${screen} displayed in ${endTime - startTime} millis [${commandType}]`)
},
willDisappear: ({screen}) => {
console.log(`Screen will disappear ${screen}`)
},
didDisappear: ({screen}) => {
console.log(`Screen disappeared ${screen}`)
}
}).register();
