Portalize

The simplest way to render anything on top of the rest.

This component is extracted from react-native-paper and has been simplified for the purpose of react-native-modalize.

Installation

yarn add react-native-portalize

Usage

import React from 'react';
import { View, Text } from 'react-native';
import { Host, Portal } from 'react-native-portalize';

export const MyApp = () => (
  <Host>
    <View>
      <Text>Some copy here and there...</Text>

      <Portal>
        <Text>A portal on top of the rest</Text>
      </Portal>
    </View>
  </Host>
);

Example with react-native-modalize and react-navigation

import React from 'react';
import { View, TouchableOpacity, Text } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import { Modalize } from 'react-native-modalize';
import { Host, Portal } from 'react-native-portalize';

const Tab = createBottomTabNavigator();

const ExamplesScreen = () => {
  const modalRef = useRef<Modalize>(null);

  const onOpen = () => {
    modalRef.current?.open();
  };

  return (
    <>
      <TouchableOpacity onPress={onOpen}>
        <Text>Open the modal</Text>
      </TouchableOpacity>

      <Portal>
        <Modalize ref={modalRef}>...your content</Modalize>
      </Portal>
    </>
  );
};

const SettingsScreen = () => (
  <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
    <Text>Settings screen</Text>
  </View>
);

export const App = () => (
  <NavigationContainer>
    <Host>
      <Tab.Navigator>
        <Tab.Screen name="Examples" component={ExamplesScreen} />
        <Tab.Screen name="Settings" component={SettingsScreen} />
