Reaction

• Reaction component has two different variants
  • Default reaction: This variant of reaction is based on an absolute view
  • Modal reaction: This variant of reaction is based on a Modal view
• To avoid the zIndex/Overlap issue, you can use modal variant of reaction component instead of the default

Usage

const ReactionItem = () => {
  const [selectedEmoji, setSelectedEmoji] = useState();
  return (
    <View>
      <Reaction items={ReactionItems} onTap={setSelectedEmoji}>
        <Text>{selectedEmoji ? selectedEmoji?.emoji : 'Like'}</Text>
      </Reaction>
    </View>
  );
};

Note: To improve the performance with Flatlist, consider wrapping your renderItem with memo. Additionally, pass state variable that will be used to manage the scroll enabled property of the Flatlist. This can further optimize the rendering of entire list.

You're not sure what this means, take a look at this example card

Modal Reaction

• Modal reaction variant can be used to avoid the zIndex / Overlap issue on reaction popup

Note: Make sure to wrap your root component with ReactionProvider

import { ReactionProvider } from 'react-native-reactions';
export default const App = () => {
  return <ReactionProvider>{/* content */}</ReactionProvider>;
}

Usage

App.tsx

Use the above App example but the only change here is to wrap the root component with ReactionProvider.

import { ReactionProvider } from 'react-native-reactions';

<ReactionProvider>
  <SafeAreaView style={styles.mainStyle}>
    <FlatList
      data={PostItemList}
      style={styles.flatlistStyle}
      scrollEnabled={isScrollEnable}
      renderItem={({ index, item }) => (
        <Card
          index={index}
          {...item}
          onShowDismissCard={(e?: boolean) => setIsScrollEnable(!e)}
          isScrollEnable
        />
      )}
      keyExtractor={item => item?.id}
    />
  </SafeAreaView>
</ReactionProvider>;

Card.tsx

Use the above Card example but the only change here is to set type as modal.

<Reaction
  items={ReactionItems}
  onTap={setSelectedEmoji}
  itemIndex={index}
  onShowDismissCard={onShowDismissCard}>
  <Text>{selectedEmoji ? selectedEmoji?.emoji : 'Like'}</Text>
</Reaction>
