How can I navigate to different screens using TouchableOpacities in a React Native FlatList?

I want to ask about Flatlist on React Native. How to make Flatlist if there are using TouchaleableOpacity and make a column. I want each of the TouchaleableOpacity can go to different Screen. Can we make it like that? Maybe make a function? Or something? Please i don’t have a clue :")

This is the result of Flatlist

enter image description here

This is my HomeScreen Code to make that flatlist on the Screenshot. As you can see, i just can make 1 TouchaleableOpacity and go to "BossScreen"

<FlatList 
    data={categoryList}
    key={3}
    numColumns={3}
    keyExtractor={(item) => item.id}
    contentContainerStyle={styles.flatListContainer}
    showsVerticalScrollIndicator={false}
    renderItem={({ item }) =>{
        return(
            <TouchableOpacity
                style={styles.button}
                onPress={
                    () => navigation.navigate('BossScreen',{ categoryId: item.id })
                }
            >
                <Image
                    source={{uri:item.icon}}
                    style={styles.icon}
                />
                <Text style={styles.itemName}>{item.name}</Text>
            </TouchableOpacity>
        )
    }}
/>

This is my MainNavigator.js

        <NavigationContainer>
            <Stack.Navigator initialRouteName="MainScreen">

                <Stack.Screen
                    name="MainScreen"
                    component={MainScreen}
                    options={{
                        title: 'ArcanePedia',
                        headerStyle: {
                            backgroundColor: '#0074C4',
                        },
                        headerTitleStyle: {
                            color: 'white',
                            fontSize: 24
                        },
                        headerLeft: null,
                        headerTitleAlign: 'center',
                    }}
                />

                    <Stack.Screen

                            headerTitleAlign: 'center',
                        }}
                    />

                            headerLeft: null,

                            }}
                        />


            </Stack.Navigator>
        </NavigationContainer>

I expecting i can still using Flatlist and make every "item" can go through on their screen.

    yes you can do that, in your catagoryList have a key value pair, eg. "screen: ‘MagicScreen’", … and then in your renderItem, just reference the key, eg.

    onPress={
    () => navigation.navigate(item.screen,{ categoryId: item.id })
}

    If I understood correctly, you want to navigate to a screen based on the pressed component. However, we need to see categoryList to give precise answer, since its rendering flatlist based on that.

    but if categoryList contains screenNames, solution would look somewhat like this:

    const screenNames = ['MagicScreen', 'FightingStyleScreen', 'WeaponScreen', 'StorylineScreen', 'StatsScreen', BossScreen];
        
    <FlatList
      data={screenNames}
      renderItem={({ item, index }) => {
        const screenName = screenNames[index];
        const params = screenName === 'BossScreen' ? { categoryId: item.id } : {};                                     

        const navigateToScreen = () => navigation.navigate(screenName, params);
    
        return (
          <TouchableOpacity style={styles.button} onPress={navigateToScreen}>
            <Image source={{ uri: item.icon }} style={styles.icon} />
            <Text style={styles.itemName}>{item.name}</Text>
          </TouchableOpacity>
        );
      }}
      keyExtractor={(item, index) => index.toString()}
    />

    u can change

    const params = screenName ===’BossScreen’ || ‘MagicScreen’ …etc

    based on which component requires item id

    You can add a separate function called renderItem and call that into your renderItem in the FlatList ,

    renderItem={({ item }) => {
  let screenName;
  let screenParams = {};

  // Determine the screen name and parameters based on the item
  switch (item.id) {
    case 'magic':
      screenName = 'MagicScreen';
      break;
    case 'fightingStyle':
      screenName = 'FightingStyleScreen';
      break;
    case 'weapons':
      screenName = 'WeaponScreen';
      break;
    // Add more cases for other items if needed

    default:
      screenName = 'BossScreen';
      screenParams = { categoryId: item.id };
      break;
  }

  return (
    <TouchableOpacity
      style={styles.button}
      onPress={() => navigation.navigate(screenName, screenParams)}
    >
      <Image source={{ uri: item.icon }} style={styles.icon} />
      <Text style={styles.itemName}>{item.name}</Text>
    </TouchableOpacity>
  );
}}

    And change your FlatList component like this ,

    <FlatList 
    data={categoryList}
    key={3}
    numColumns={3}
    keyExtractor={(item) => item.id}
    contentContainerStyle={styles.flatListContainer}
    showsVerticalScrollIndicator={false}
    renderItem={renderItem}
/>

    Each TouchableOpacity in your FlatList will navigate to a different screen based on the item.id. Just make sure to update the screen names and parameters according to your actual screen components and requirements.
