Simple remove transition animation in react native

Published at

1/4/2025

Hello Devs

Today I would like to share a bit of item remove animation code (translate / scale animation) in react native.

Here's a glimpse of what I've prepared.

Suppose, you have a list of items in your project (very common example, which most of us deal with in our day to day projects).

export interface ItemEntity {
  id: number;
  taskTitle: string;
}

export const sampleItems: Array<ItemEntity> = [
  {
    id: 1,
    taskTitle: "Breakfast",
  },
  {
    id: 2,
    taskTitle: "Lunch",
  },
  {
    id: 3,
    taskTitle: "Sports",
  },
  {
    id: 4,
    taskTitle: "Dinner",
  },
];

And these items populated into a flat list for displaying inside a react native application

// state data items to be populated in flat list
 const [dataItems, setDataItems] = useState<Array<ItemEntity>>(sampleItems);

// Handler function to remove the item (after animation ends)
  const _handleAfterRemovedAction = (givenEntity: ItemEntity) => {
    setDataItems(
      dataItems.filter(
        (itemIterated: ItemEntity) => itemIterated.id !== givenEntity.id,
      ),
    );
  };

// item in a list
const _renderItem = ({item, index}: {item: ItemEntity; index: number}) => {
    return (
      <ListViewItem
        itemEntity={item}
        onTaskCompletedWithAnimation={_handleAfterRemovedAction}
      />
    );
  };

// Flat List component with some styles
<FlatList
      style={stylesToUse.listViewStyle}
      contentContainerStyle={stylesToUse.listViewContentContainerStyle}
      ListHeaderComponent={_renderHeader()}
      data={dataItems}
      keyExtractor={(item: ItemEntity, index: number) =>
        `${item.id}_${item.taskTitle}_${index}`
      }
      renderItem={_renderItem}
      ItemSeparatorComponent={_renderSeparator}
      showsVerticalScrollIndicator={false}
    />

Now, the animation magic happens in our item component on the click of remove button.

Code Snippet

import {Animated} from 'react-native';

 const _removeItemWithAnimation = () => {
    Animated.parallel([
      Animated.timing(translateAnim, {
        // Negative Value: Translate to left, Positive Value: Translate to right
        toValue: -1000,
        duration: 800,
        useNativeDriver: true,
      }),
    ]).start(() => { /** on end of animation, this block executes, handle your removal logic */});
  };

Full code

ListViewItem.tsx

import {Animated, Text, TouchableOpacity, View} from 'react-native';
import {ItemEntity} from '../../data/ItemEntity';
import {listViewItemStyles} from './styles/ListViewItem.styles';

export type PropsListViewItem = {
  itemEntity: ItemEntity;
  onTaskCompletedWithAnimation?: (givenItem: ItemEntity) => void;
};

export const ListViewItem = ({
  itemEntity,
  onTaskCompletedWithAnimation,
}: PropsListViewItem) => {
  const stylesToUse = listViewItemStyles;

  const translateAnim = new Animated.Value(0); // Initial position

  // trigger remove animation
  const _removeItemWithAnimation = () => {
    Animated.parallel([
      Animated.timing(translateAnim, {
        // Negative Value: Translate to left, Positive Value: Translate to right
        toValue: -1000,
        duration: 800,
        useNativeDriver: true,
      }),
    ]).start(() => onTaskCompletedWithAnimation?.(itemEntity));
  };

  const _renderTitle = () => {
    return (
      <Text style={stylesToUse.titleTextStyle}>{itemEntity.taskTitle}</Text>
    );
  };

  const _renderRemoveAction = () => {
    return (
      <TouchableOpacity
        style={stylesToUse.deleteButtonContainer}
        onPress={() => {
          _removeItemWithAnimation();
        }}>
        <Text style={stylesToUse.deleteButtonTextStyle}>Remove</Text>
      </TouchableOpacity>
    );
  };

  return (
    <Animated.View
      style={[
        stylesToUse.container,
        {
          transform: [{translateX: translateAnim}]
        },
      ]}>
      <View style={stylesToUse.row}>
        {/* Task Title */}
        {_renderTitle()}

        {/* Remove button */}
        {_renderRemoveAction()}
      </View>
    </Animated.View>
  );
};

ListViewItem.styles.ts

import {StyleSheet} from 'react-native';

export const listViewItemStyles = StyleSheet.create({
  container: {
    backgroundColor: '#e1e1e1',
    borderRadius: 8,
    elevation: 1,
  },

  row: {
    padding: 20,
    flexDirection: 'row',
    alignItems: 'center',
    gap: 8,
  },

  titleTextStyle: {
    flex: 1,
    fontSize: 16,
    fontWeight: '500',
    color: '#212121',
  },

  deleteButtonContainer: {
    paddingHorizontal: 12,
    paddingVertical: 8,
    backgroundColor: '#EF5350',
    borderRadius: 24,
  },

  deleteButtonTextStyle: {
    fontSize: 12,
    color: '#ffffff',
  },
});

The translation removal animation can be relevant in following use cases.

Marking a task as done/incomplete.
Remove an item from the list (we just did)
Archiving an item etc.

BONUS

We can also combine the translate animation with scale animation.

const scaleAnim = new Animated.Value(1); // Initial scale value

  const _removeItemWithAnimation = () => {
    Animated.parallel([
      Animated.timing(translateAnim, {
        // Negative Value: Translate to left, Positive Value: Translate to right
        toValue: -1000,
        duration: 800,
        useNativeDriver: true,
      }),
       Animated.timing(scaleAnim, {
        // toValue 0 indicates the item will shrink to size 0
        toValue: 0,
        duration: 800,
        useNativeDriver: true,
      }),
    ]).start(() => onTaskCompletedWithAnimation?.(itemEntity));
  };

And our animated view (in ListViewItem.tsx)

   <Animated.View
      style={[
        stylesToUse.container,
        {
          transform: [{translateX: translateAnim}, {scale: scaleAnim}], 
        },
      ]}> ...

Play around with duration and toValue to experience yourself.

Or you can just use scale animation and omit translate animation based on your requirement.

Quick Bytes:

Translation - Translation refers to moving of an item from one direction to the other or we can say position of an item changes entirely.
Scale - Item's height/width updates. Either it's enlarged or it shrinks.

Happy coding.
