How to Pass Parameters to screen in StackNavigator?

In react hooks, params send in navigation using useNavigation

import { useNavigation } from '@react-navigation/native';

const navigation = useNavigation();

<Button
      title="Back"
      onPress={() => {
        navigation.navigate('MyScreen',{name:'test'});
      }}
    />

then access them using useNavigationParam

function MyScreen() {
  const name = useNavigationParam('name');
  return <p>name is {name}</p>;
}

See this .

It solved my problem.

this.props.navigation.navigate("**stack_Name**", {
 screen:"screen_name_connect_with_**stack_name**",
 params:{
 user:"anything_string_or_object"
}
})

In your first page, say CountriesList

const CountriesList = ({ navigation }) => {

/* Function to navigate to 2nd screen */
  const viewCountry = (country) => {
    navigation.navigate('ListItemPageRoute', { name: country.country_name });
  };
}

For your second page name, say ListItemPageRoute

const ListItemPageRoute = (props) => {

return (
    <View style={styles.container}>
        <Text style={styles.countryText}> { props.route.params.name } </Text>
    </View>
  );
};

'Props.route' Object will have the list of all parameters you would like to pass from one screen to another.

You can pass params with the navigate function's second argument:

onPress(user) {
  this.props.navigation.navigate(
    'DetailPage',
    { user },
  );
}
