问题 I'm using react-navigation and I have a dynamic header, so I'm using setParams and getting it in the title. const MyComponent = ({navigation}) => { useEffect(() => { const { setParams, state } = navigation const { params = {} } = state const { description } = params setParams({ headerTitle: description }) }, []) return (...) } MyComponent.navigationOptions = ({ navigation }) => ({ title: navigation.getParam('headerTitle') }) The problem here is that I only want to setParams once (so I use []

问题 As they point out in the docs, they've gotten rid of the 4 navigation event listeners and instead decided to use Lifecycle events. But the problem I'm running into with React Navigation 5 is that the blur event doesn't work as I need it to! Before, I could add an onWillBlur listener, and do stuff when the user temporarily leaves (not closes) the app (such as close a socket connection, and then reopen it when the user reenters the app). How can I replicate the onWillBlur or onDidBlur events
