react-native-modal

The aim of react-native-modal is to handle multiple modals opening one after the other and independent of each other.

React native older version package

@kalwani/react-native-modal

Description

If there are multiple modals in your application ( in different components or same ) that do not need to communicate with each other but could be in a state where one modal is already visible to the user and the second could open itself causing unwanted behaviour, in such a scenario the library will close the first modal ( that was already open ) and show the second modal. If a third modal opens while the second is visible to the user, it'll close the second modal and show the third.

Setup

This library is available on npm, install it with: npm i @neidercode/react-native-modal

Usage

react-native-modal is simply a powerful extension on top of react-native's modal component, hence it works in a similar fashion

Import react-native-modal:

import Modal from "@neidercode/react-native-modal";

Simply show/hide the modal by changing the isVisible prop to true/false. The onModalHide is the function which will execute when the modal closes (either due to it's own state change or due to some other modal forcing it to close), both these props are required:

state = { showModal: true }

render () {
  closeModal = () => {
    this.setState({ showModal: false })
  }
  
  return (
    <View>
      <Modal isVisible={showModal} onModalHide={this.closeModal} >
        <View style={{ flex: 1 }}>
          <Text>I am the modal content!</Text>
        </View>
      </Modal>
    </View>
  )
}

A complete example

The following example consists of a component (ModalTester) which opens three modals one after the other at 2, 4 and 6 seconds and each of it is independent of the other. The state of these modals are controlled by modal1 modal2 modal3 values.

import React, { Component } from "react";
import { View, Text } from "react-native";
import Modal from "@neidercode/react-native-modal";

export default class ModalTester extends Component {
  state = {
    modal1: false,
    modal2: false,
    modal3: false
  };

  style = {
    color: "white",
    alignItems: "center",
    justifyContent: "center",
    fontSize: 20
  }

  componentWillMount() {
    setTimeout(() => {
      this.setState({ modal1: true });
    }, 2000);

    setTimeout(() => {
      this.setState({ modal2: true });
    }, 4000);

    setTimeout(() => {
      this.setState({ modal3: true });
    }, 6000);
  }

  closeModalOne = () => {
    this.setState({ modal1: false });
  };
  closeModalTwo = () => {
    this.setState({ modal2: false });
  };
  closeModalThree = () => {
    this.setState({ modal3: false });
  };

  render() {
    const { modal1, modal2, modal3 } = this.state;
    return (
      <View>
        <Modal
          isVisible={modal1}
          onModalHide={this.closeModalOne}
          style={{ backgroundColor: "red" }}
        >
          <View>
            <Text style={this.style}>
              This is modal 1
            </Text>
          </View>
        </Modal>

        <Modal
          isVisible={modal2}
          onModalHide={this.closeModalTwo}
          style={{ backgroundColor: "green" }}
        >
          <View>
            <Text style={this.style}>
              This is modal 2
            </Text>
          </View>
        </Modal>

        <Modal
          isVisible={modal3}
          onModalHide={this.closeModalThree}
          style={{ backgroundColor: "blue" }}
        >
          <View>
            <Text style={this.style}>
              This is modal 3
            </Text>
          </View>
        </Modal>
      </View>
    );
  }
}
