  );

export default Screen2;

This is my consumer part is which I want to display the text which is present in getEmail in Text View. please help to solve this problem.

CodePudding user response：

The issue is that LoginContexts.Consumer component expects a render function.

Context.Consumer

<MyContext.Consumer>
  {value => /* render something based on the context value */}
</MyContext.Consumer>

The useContext hook is the consumer, remove the LoginContexts.Consumer component.

function Screen2() {
  const {getEmail} = useContext(LoginContexts);
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>{getEmail}</Text>
    </View>
  );
}
