react-native-modal

An enhanced, animated and customizable react-native modal.

The aim 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

Demo

Setup

This library is available on npm, install it with: npm install --save 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";

2. 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>
    )
  }

3. 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 { Text, TouchableOpacity, 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 }}>
        <TouchableOpacity onPress={this._toggleModal}>
          <Text>Show Modal</Text>
        </TouchableOpacity>
        <Modal isVisible={this.state.isModalVisible}>
          <View style={{ flex: 1 }}>
            <Text>Hello!</Text>
            <TouchableOpacity onPress={this._toggleModal}>
              <Text>Hide me!</Text>
            </TouchableOpacity>
          </View>
        </Modal>
      </View>
    );
  }
}

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)

Checkout the package react-native-extra-dimensions-android

To use, here's an example:

const IOS = Platform.OS === "ios";
const WIDTH = Dimensions.get("window").width;
const HEIGHT = IOS
  ? Dimensions.get("window").height
  : require("react-native-extra-dimensions-android").get("REAL_WINDOW_HEIGHT");

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 onSwipe allows you to handle this situation (remember to set swipeDirection too!):

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

The modal flashes in a weird way when animating

Unfortunately this is a know 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.

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.
