Answered 2020-May-27 at 16:50The problem is the you are accessing navigation outside the navigation stack. When you moved the flatlist to to ArticleList its outside the navigation and it wont get the navigation prop. You can handle this in two ways.
You can simply pass the navigation from the main screen
function MainScreen({ navigation }) { return ( {/* show the data in a flatlist */} < ArticleList navigation={navigation} /> ); }
You can use the useNavigation hook to access navigation outside navigation.

this issue i have been facing from several days i an making a function component. i am changing the state by onPress method the console is giving me the same data tha i wanted but it is not re-rendering with the updated data. this is the snack link

Answered 2020-May-12 at 09:31The reason your state update doens't cause a re-render is because you are mutating the state while updating and react doesn't think that the state has changed because the reference hasnt updated
You need to clone and update the state
