I like to know how i can use React Navigation on FlatList property, where the name of the Stack.Screen comes from a .json
file.
And with that, when the user click on that Item, they goes to another page of the application.
Data
{
Data: [
{
"key": "0",
"label": "Test",
"goTo": "Test", <--- Here goes the name of Stack.Screen from routes.js
}
]
}
FlatList structure
function Item({ label, goTo }) {
return (
<Ripple rippleCentered onPressIn={goTo}> // (react-native-material-ripple)
<Option>
<Icon name={onIcon} size={28} color={onColor} /> // (react-native-vector-icons)
<OptionLabel color={onColor}>{label}</OptionLabel>
</Option>
</Ripple>
);
}
I've already tried to use navigation.navigate({goTo})
on onPressIn
property from Ripple, but a ReferenceError appears: Can't find variable: navigation
Final exported component
export default class Menu extends Component {
render() {
return (
<Container color={this.props.color}>
<FlatList
data={Data}
showsVerticalScrollIndicator={false}
keyExtractor={item => item.key}
numColumns={5}
columnWrapperStyle={Styles.Row}
renderItem={({ item }) =>
<Item
goTo={item.goTo}
label={item.label}
/>
}
/>
</Container>
);
}
}
import json from './myfile.json'; // reading from json file
export default class Menu extends Component {
render() {
return (
<Container color={this.props.color}>
<FlatList
data={json.Data} // accessing Data from json
showsVerticalScrollIndicator={false}
keyExtractor={item => item.key}
numColumns={5}
columnWrapperStyle={Styles.Row}
renderItem={({ item }) =>
<Item
goTo={item.goTo}
label={item.label}
/>
}
/>
</Container>
);
}
}
You could use useNavigation
hook to call navigation.navigate(goTo)
e.g.
import { useNavigation } from '@react-navigation/native';
function Item({ label, goTo }) {
const navigation = useNavigation(); // navigation hook
return (
<Ripple rippleCentered onPressIn={() => navigation.navigate(goTo)}> // navigate to goTo screen
<Option>
<Icon name={onIcon} size={28} color={onColor} />
<OptionLabel color={onColor}>{label}</OptionLabel>
</Option>
</Ripple>
);
}
Please notice that Menu
needs to be under NavigationContainer
so useNavigation
can work.
