Automatically animates views to their new positions when the next layout happens. A common way to use this API is to call it before updating the state hook in functional components and calling setState in class components. Note that in order to get this to work on Android you need to set the following flags via UIManager:

if (Platform.OS === 'android') {
  if (UIManager.setLayoutAnimationEnabledExperimental) {
    UIManager.setLayoutAnimationEnabledExperimental(true);
  }
}

Example

import React, {useState} from 'react';
import {
  LayoutAnimation,
  Platform,
  StyleSheet,
  Text,
  TouchableOpacity,
  UIManager,
  View,
} from 'react-native';
import {SafeAreaView, SafeAreaProvider} from 'react-native-safe-area-context';

if (
  Platform.OS === 'android' &&
  UIManager.setLayoutAnimationEnabledExperimental
) {
  UIManager.setLayoutAnimationEnabledExperimental(true);
}
const App = () => {
  const [expanded, setExpanded] = useState(false);

  return (
    <SafeAreaProvider>
      <SafeAreaView style={style.container}>
        <TouchableOpacity
          onPress={() => {
            LayoutAnimation.configureNext(LayoutAnimation.Presets.spring);
            setExpanded(!expanded);
          }}>
          <Text>Press me to {expanded ? 'collapse' : 'expand'}!</Text>
        </TouchableOpacity>
        {expanded && (
          <View style={style.tile}>
            <Text>I disappear sometimes!</Text>
          </View>
        )}
      </SafeAreaView>
    </SafeAreaProvider>
  );
};

const style = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    gap: 16,
  },
  tile: {
    backgroundColor: 'lightgrey',
    borderWidth: 0.5,
    borderColor: '#d6d7da',
    padding: 4,
  },
});

export default App;

Methods

`configureNext()`

static configureNext(
  config: LayoutAnimationConfig,
  onAnimationDidEnd?: () => void,
  onAnimationDidFail?: () => void,
);

Schedules an animation to happen on the next layout.

Parameters:

Name	Type	Required	Description
config	object	Yes	See config description below.
onAnimationDidEnd	function	No	Called when the animation finished.
onAnimationDidFail	function	No	Called when the animation failed.

The config parameter is an object with the keys below. create returns a valid object for config, and the Presets objects can also all be passed as the config.

duration in milliseconds
create, optional config for animating in new views
update, optional config for animating views that have been updated
delete, optional config for animating views as they are removed

The config that’s passed to create, update, or delete has the following keys:

type, the animation type to use
property, the layout property to animate (optional, but recommended for create and delete)
springDamping (number, optional and only for use with type: Type.spring)
initialVelocity (number, optional)
delay (number, optional)
duration (number, optional)

`create()`


static create(duration, type, creationProp)

Helper that creates an object (with create, update, and delete fields) to pass into configureNext. The type parameter is an animation type, and the creationProp parameter is a layout property. Example:

import React, {useState} from 'react';
import {
  View,
  Platform,
  UIManager,
  LayoutAnimation,
  StyleSheet,
  Button,
} from 'react-native';

if (
  Platform.OS === 'android' &&
  UIManager.setLayoutAnimationEnabledExperimental
) {
  UIManager.setLayoutAnimationEnabledExperimental(true);
}

const App = () => {
  const [boxPosition, setBoxPosition] = useState('left');

  const toggleBox = () => {
    LayoutAnimation.configureNext({
      duration: 500,
      create: {type: 'linear', property: 'opacity'},
      update: {type: 'spring', springDamping: 0.4},
      delete: {type: 'linear', property: 'opacity'},
    });
    setBoxPosition(boxPosition === 'left' ? 'right' : 'left');
  };

  return (
    <View style={styles.container}>
      <View style={styles.buttonContainer}>
        <Button title="Toggle Layout" onPress={toggleBox} />
      </View>
      <View
        style={[styles.box, boxPosition === 'left' ? null : styles.moveRight]}
      />
    </View>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    alignItems: 'flex-start',
    justifyContent: 'center',
  },
  box: {
    height: 100,
    width: 100,
    borderRadius: 5,
    margin: 8,
    backgroundColor: 'blue',
  },
  moveRight: {
    alignSelf: 'flex-end',
    height: 200,
    width: 200,
  },
  buttonContainer: {
    alignSelf: 'center',
  },
});

export default App;
