After not succeeding in solving my problem here, I had to create a new question with all my classes in it.
I am new to react native and have a problem figuring out how to navigate from one class to another one with passing parameters and would appreciate your help.
All I want to do is:
- SessionCreate with flatlist containing CustomButton
- Navigate from SessionCreate to ItemConfig by clicking CustomButton
- Pass parameter "element" to ItemConfig
- Show content of parameter passed in ItemConfig
With this setup an empty "element" is passed as parameter to the ItemConfigScreen (but no error occurs):
app.js:
//Views
function Home({ navigation }) {
return (
<HomeScreen />
);
}
function Session({ navigation }) {
return (
<SessionScreen />
);
}
//subviews
function SessionCreate({ navigation }) {
return (
<SessionCreateScreen />
);
}
function ItemConfig({ navigation }) {
return (
<ItemConfigScreen />
);
}
//navigation stacks
const SessionStack = createStackNavigator();
function SessionStackScreen({ navigation }) {
return (
<SessionStack.Navigator>
<SessionStack.Screen
name="Session"
component={Session}
options={{ tabBarLabel: 'Session!' }}
/>
<SessionStack.Screen
name="SessionCreate"
component={SessionCreate}
options={{ tabBarLabel: 'SessionCreate!' }}
/>
<SessionStack.Screen
name="ItemConfig"
component={ItemConfig}
options={{ tabBarLabel: 'ItemConfig!' }}
/>
</SessionStack.Navigator>
);
}
//Navbar Bottom
const Tab = createBottomTabNavigator();
function App() {
return (
<View style={[theme.colcontainer, { flexDirection: "column" }]} >
<NavigationContainer>
<Tab.Navigator
screenOptions={({ route }) => ({
tabBarIcon: ({ focused, color, size }) => {
let iconName;
if (route.name === 'Home') {
iconName = focused ? 'home' : 'home-outline';
} else if (route.name === 'Session') {
iconName = focused ? 'book' : 'book-outline';
}
// dynamic ionicon
return <Ionicons name={iconName} size={size} color={color} />;
},
})}
>
<Tab.Screen name="Home" component={Home} />
<Tab.Screen name="Session" component={SessionStackScreen} />
</Tab.Navigator>
</NavigationContainer>
</View >
);
}
export default App;
SessionScreen.js:
function SessionScreen() {
const navigation = useNavigation();
return (
<View style={[theme.container, { flexDirection: "column" }]} >
<View>
<TouchableOpacity onPress={() => navigation.navigate('SessionCreate')}>
<Text >Create Session</Text>
</TouchableOpacity>
</View>
</View >
);
}
export default SessionScreen;
SessionCreateScreen.js:
//data
const sessionElements = [
{
id: "1",
title: "title1"
}
];
function SessionCreateScreen() {
const navigation = useNavigation()
const renderItemConfiguration = ({ item }) => (
<CustomButton element={item.title} onPress={() => navigation.navigate('ItemConfig', { element: 'item.title' })} />
);
return (
<View style={{ flexDirection: "column", flex: 2}} >
<SafeAreaView >
<FlatList
data={sessionElements}
renderItem={renderItemConfiguration}
keyExtractor={(item) => item.id}
/>
</SafeAreaView>
</View >
);
}
export default SessionCreateScreen;
ItemConfigScreen.js:
const element = "";
function ItemConfigScreen() {
return (
<ScrollView >
<View style={{ flexDirection: "column", flex: 2}} >
<Text>Configure {element} here</Text>
</View >
</ScrollView>
);
}
export default ItemConfigScreen;
Any help is appreciated.
