react-native-modal

npm version styled with prettier

An enhanced, animated and customizable react-native modal.

The goal of react-native-modal is expanding the original react-native Modal component by adding animations and styles customization options while still providing a plain-simple API.

Features

  • Smooth enter/exit animations
  • Plain simple and flexible APIs
  • Customizable backdrop opacity, color and timing
  • Listeners for the modal animations ending
  • Resize itself correctly on device rotation
  • Swipeable
  • Scrollable

Setup

This library is available on npm, install it with: npm i react-native-modal or yarn add react-native-modal.

Usage

Since react-native-modal is an extension of the original react native modal, it works in a similar fashion react-native original modal.

  1. Import react-native-modal:
import Modal from 'react-native-modal';
  1. Create a modal and nest its content inside of it:
render () {
    return (
      <View>
        <Modal>
          <View style={{ flex: 1 }}>
            <Text>I am the modal content!</Text>
          </View>
        </Modal>
      </View>
    )
  }
  1. Then simply show it by setting the isVisible prop to true:
render () {
    return (
      <View>
        <Modal isVisible={true}>
          <View style={{ flex: 1 }}>
            <Text>I am the modal content!</Text>
          </View>
        </Modal>
      </View>
    )
  }

The isVisible prop is the only prop you'll really need to make the modal work: you should control this prop value by saving it in your state and setting it to true or false when needed.

A complete example

The following example consists in a component (ModalTester) with a button and a modal. The modal is controlled by the isModalVisible state variable and it is initially hidden, since its value is false.
Pressing the button sets isModalVisible to true, making the modal visible.
Inside the modal there is another button that, when pressed, sets isModalVisible to false, hiding the modal.

import React, {Component} from 'react';
import {Button, Text, View} from 'react-native';
import Modal from 'react-native-modal';
 
export default class ModalTester extends Component {
  state = {
    isModalVisible: false,
  };
 
  toggleModal = () => {
    this.setState({isModalVisible: !this.state.isModalVisible});
  };
 
  render() {
    return (
      <View style={{flex: 1}}>
        <Button title="Show modal" onPress={this.toggleModal} />
        <Modal isVisible={this.state.isModalVisible}>
          <View style={{flex: 1}}>
            <Text>Hello!</Text>
            <Button title="Hide modal" onPress={this.toggleModal} />
          </View>
        </Modal>
      </View>
    );
  }
}

For a more complex example take a look at the /example directory.

Frequently Asked Questions

The component is not working as expected

Under the hood react-native-modal uses react-native original Modal component.
Before reporting a bug, try swapping react-native-modal with react-native original Modal component and, if the issue persists, check if it has already been reported as a react-native issue.

The backdrop is not completely filled/covered on some Android devices (Galaxy, for one)

React-Native has a few issues detecting the correct device width/height of some devices.
If you're experiencing this issue, you'll need to install react-native-extra-dimensions-android.
Then, provide the real window height (obtained from react-native-extra-dimensions-android) to the modal:

render() {
  const deviceWidth = Dimensions.get("window").width;
  const deviceHeight = Platform.OS === "ios"
    ? Dimensions.get("window").height
    : require("react-native-extra-dimensions-android").get("REAL_WINDOW_HEIGHT");
 
  return (
  <Modal
    isVisible={this.state.isVisible}
    deviceWidth={deviceWidth}
    deviceHeight={deviceHeight}
  >
    <View style={{ flex: 1 }}>
      <Text>I am the modal content!</Text>
    </View>
  </Modal>
  )
}

How can I hide the modal by pressing outside of its content?

The prop onBackdropPress allows you to handle this situation:

<Modal
  isVisible={this.state.isVisible}
  onBackdropPress={() => this.setState({isVisible: false})}>
  <View style={{flex: 1}}>
    <Text>I am the modal content!</Text>
  </View>
</Modal>

How can I hide the modal by swiping it?

The prop onSwipeComplete allows you to handle this situation (remember to set swipeDirection too!):

<Modal
  isVisible={this.state.isVisible}
  onSwipeComplete={() => this.setState({isVisible: false})}
  swipeDirection="left">
  <View style={{flex: 1}}>
    <Text>I am the modal content!</Text>
  </View>
</Modal>

Note that when using useNativeDriver={true} the modal won't drag correctly. This is a known issue.

The modal flashes in a weird way when animating

Unfortunately this is a known issue that happens when useNativeDriver=true and must still be solved.
In the meanwhile as a workaround you can set the hideModalContentWhileAnimating prop to true: this seems to solve the issue. Also, do not assign a backgroundColor property directly to the Modal. Prefer to set it on the child container.

The modal background doesn't animate properly

Are you sure you named the isVisible prop correctly? Make sure it is spelled correctly: isVisible, not visible.

The modal doesn't change orientation

Add a supportedOrientations={['portrait', 'landscape']} prop to the component, as described in the React Native documentation.

Also, if you're providing the deviceHeight and deviceWidth props you'll have to manually update them when the layout changes.

I can't show multiple modals one after another

Unfortunately right now react-native doesn't allow multiple modals to be displayed at the same time. This means that, in react-native-modal, if you want to immediately show a new modal after closing one you must first make sure that the modal that your closing has completed its hiding animation by using the onModalHide prop.

I can't show multiple modals at the same time

See the question above. Showing multiple modals (or even alerts/dialogs) at the same time is not doable because of a react-native bug. That said, I would strongly advice against using multiple modals at the same time because, most often than not, this leads to a bad UX, especially on mobile (just my opinion).

The StatusBar style changes when the modal shows up

This issue has ben discussed here.
The TLDR is: it's a know React-Native issue with the Modal component 😞

The modal is not covering the entire screen

The modal style applied by default has a small margin.
If you want the modal to cover the entire screen you can easily override it this way:

<Modal style={{margin: 0}}>...</Modal>

I can't scroll my ScrollView inside of the modal

Enable propagateSwipe to allow your child components to receive swipe events:

<Modal propagateSwipe>...</Modal>

Please notice that this is still a WIP fix and might not fix your issue yet, see issue #236.

The modal enter/exit animation flickers

Make sure your animationIn and animationOut are set correctly.
We noticed that, for example, using fadeIn as an exit animation makes the modal flicker (it should be fadeOut!). Also, some users have noticed that setting backdropTransitionOutTiming={0} can fix the flicker without affecting the animation.

The custom backdrop doesn't fill the entire screen

You need to specify the size of your custom backdrop component. You can also make it expand to fill the entire screen by adding a flex: 1 to its style:

<Modal
  isVisible={this.state.isVisible}
  customBackdrop={<View style={{flex: 1}} />}>
  <View style={{flex: 1}}>
    <Text>I am the modal content!</Text>
  </View>
</Modal>

The custom backdrop doesn't dismiss the modal on press

You can provide an event handler to the custom backdrop element to dismiss the modal. The prop onBackdropPress is not supported for a custom backdrop.

<Modal
  isVisible={this.state.isVisible}
  customBackdrop={
    <TouchableWithoutFeedback onPress={dismissModalHandler}>
      <View style={{flex: 1}} />
    </TouchableWithoutFeedback>
  }
/>

Available animations

Take a look at react-native-animatable to see the dozens of animations available out-of-the-box. You can also pass in custom animation definitions and have them automatically register with react-native-animatable. For more information on creating custom animations, see the react-native-animatable animation definition schema.
