Currently, I was taking a course:Multiplatform Mobile App Development with React Native in coursera, and I was stuck at after every lecture because the instructor use react-navigation@2.0.1
but I want to make sure to learn the latest version(v5). In this lecture he created a stack navigator and bring an icon to a screen like,
import {createStackNavigator} from 'react-navigation';
import { Icon } from 'react-native-elements';
const MenuNavigator = createStackNavigator(
{
Menu: {
screen: Menu,
navigationOptions: ({ navigation }) => ({
headerLeft: (
<Icon
name="menu"
size={24}
color="white"
onPress={() => navigation.toggleDrawer()}
/>
),
}),
},
Dishdetail: { screen: Dishdetail },
},
{
initialRouteName: 'Menu'
}
);
Where navigationOptions
can be an object or be a function that takes in props.
I convert it like,
import { createStackNavigator } from '@react-navigation/stack';
import { Icon } from 'react-native-elements';
const MenuNavigator = createStackNavigator();
function MenuNavigatorScreen() {
return (
<MenuNavigator.Navigator
initialRouteName="Menu"
screenOptions={HeaderOptions}
>
<MenuNavigator.Screen
name="Menu"
component={Menu}
/>
<MenuNavigator.Screen
name="Dishdetail"
component={Dishdetail}
options={{ headerTitle: 'Dish Detail' }}
/>
</MenuNavigator.Navigator>
);
}
But I was confused how to convert the navigationOptions
functionality into my code. Because their docs didn't tell how to trun my options
object into a function to bring the navigation
prop?
One more thing is he was using drawerIcon
,
const MainNavigator = createDrawerNavigator(
{
navigationOptions: {
drawerLabel: 'Login',
drawerIcon: ({ tintColor }) => (
<Icon
name="sign-in"
type="font-awesome"
size={24}
color={tintColor}
/>
),
}
...
But I didn't find anything related drawerIcon
in Drawer navigation docs
I heartily thank if anyone helps me to figure out this.
First of all, The options prop can be used to configure individual screens inside the navigator. And headerLeft is a function that returns a React element to display on the left side of the header. When a function is used, it receives several arguments when rendered (onPress, label, labelStyle, and more - check types.tsx for the complete list).
options = {
({
navigation
}) => ({
headerLeft: () => ( <
Icon name = 'menu'
size = {
24
}
color = 'white'
onPress = {
() =>
navigation.toggleDrawer()
}
/>
)
})
}
And for drawerIcon
use:
options = {
{
drawerIcon: ({
tintColor
}) => ( <
Icon name = 'home'
type = 'font-awesome'
size = {
24
}
color = {
tintColor
}
/>
)
}
}
