Key Features That Set React Native Elements Apart

React Native Elements boasts an impressive array of features that make it a go-to choice for many developers:

  • Cross-Platform Compatibility: Seamlessly works on both iOS and Android platforms.
  • Customizable Components: Easily adapt components to match your app’s unique style.

Getting Started with React Native Elements

Installation

To begin using React Native Elements in your project, you’ll need to install it along with its peer dependencies. Here’s how you can do it using npm or yarn:

Using npm:

npm install react-native-elements react-native-vector-icons react-native-safe-area-context

Using yarn:

yarn add react-native-elements react-native-vector-icons react-native-safe-area-context

After installation, you’ll need to link react-native-vector-icons. For React Native 0.60 and above, this process is typically automatic.

Basic Usage: Creating Your First Component

Let’s start by creating a simple button using React Native Elements. This example demonstrates how easy it is to get up and running with the library.

import React from 'react';
import { View } from 'react-native';
import { Button } from 'react-native-elements';

const MyComponent = () => {
  return (
    <View>
      <Button
        title="Click me!"
        onPress={() => console.log('Button pressed')}
      />
    </View>
  );
};

export default MyComponent;

In this example, we import the Button component from react-native-elements and use it within our custom component. The Button comes with built-in styling and a press handler, showcasing the simplicity of using React Native Elements.

Customizing Components: Making It Your Own

One of the strengths of React Native Elements is its customizability. Let’s enhance our button with some custom styling:

import React from 'react';
import { View } from 'react-native';
import { Button, ThemeProvider } from 'react-native-elements';

const MyCustomButton = () => {
  return (
    <ThemeProvider>
      <View>
        <Button
          title="Stylish Button"
          buttonStyle={{
            backgroundColor: 'rgba(78, 116, 289, 1)',
            borderRadius: 30,
          }}
          containerStyle={{
            width: 200,
            marginHorizontal: 50,
            marginVertical: 10,
          }}
          titleStyle={{ fontWeight: 'bold' }}
        />
      </View>
    </ThemeProvider>
  );
};

export default MyCustomButton;

This example introduces the ThemeProvider and demonstrates how to apply custom styles to the button. The buttonStyle, containerStyle, and titleStyle props allow for granular control over the button’s appearance.

Advanced Techniques: Elevating Your UI

Implementing a Custom Theme

Theming is a powerful feature of React Native Elements that allows you to maintain consistency across your app. Here’s how you can create and apply a custom theme:

import React from 'react';
import { ThemeProvider, Button, Text } from 'react-native-elements';

const theme = {
  colors: {
    primary: '#0066cc',
  },
  Button: {
    raised: true,
  },
};

const ThemedApp = () => {
  return (
    <ThemeProvider theme={theme}>
      <Button title="Themed Button" />
      <Text h4>Themed Text</Text>
    </ThemeProvider>
  );
};

export default ThemedApp;

This example defines a custom theme with a primary color and default button style. The ThemeProvider wraps the entire app, ensuring that all child components inherit these theme properties.

Creating Complex Layouts with Cards

Cards are versatile components that can help structure your UI. Let’s create a more complex layout using the Card component:

import React from 'react';
import { View } from 'react-native';
import { Card, Text, Button, Icon } from 'react-native-elements';

const ComplexCard = () => {
  return (
    <View>
      <Card>
        <Card.Title>HELLO WORLD</Card.Title>
        <Card.Divider />
        <Card.Image
          source={{ uri: 'https://via.placeholder.com/150' }}
          style={{ padding: 0 }}
        />
        <Text style={{ marginBottom: 10 }}>
          The idea with React Native Elements is more about component structure than actual design.
        </Text>
        <Button
          icon={<Icon name='code' color='#ffffff' />}
          buttonStyle={{ borderRadius: 0, marginLeft: 0, marginRight: 0, marginBottom: 0 }}
          title='VIEW NOW'
        />
      </Card>
    </View>
  );
};

export default ComplexCard;

This example showcases how to build a complex card layout with an image, text, and a button. The Card component provides a structured way to present information, while allowing for customization of its contents.

Implementing a Search Bar with Autocomplete

Search functionality is crucial for many apps. Here’s how you can implement a search bar with autocomplete using React Native Elements:

import React, { useState } from 'react';
import { View, FlatList } from 'react-native';
import { SearchBar, ListItem } from 'react-native-elements';

const data = [
  { id: '1', title: 'React' },
  { id: '2', title: 'React Native' },
  { id: '3', title: 'JavaScript' },
  // ... more items
];

const SearchComponent = () => {
  const [search, setSearch] = useState('');
  const [filteredData, setFilteredData] = useState(data);

  const updateSearch = (text: string) => {
    setSearch(text);
    const filtered = data.filter(item =>
      item.title.toLowerCase().includes(text.toLowerCase())
    );
    setFilteredData(filtered);
  };

  return (
    <View>
      <SearchBar
        placeholder="Type Here..."
        onChangeText={updateSearch}
        value={search}
      />
      <FlatList
        data={filteredData}
        renderItem={({ item }) => (
          <ListItem bottomDivider>
            <ListItem.Content>
              <ListItem.Title>{item.title}</ListItem.Title>
            </ListItem.Content>
          </ListItem>
        )}
        keyExtractor={item => item.id}
      />
    </View>
  );
};

export default SearchComponent;

This advanced example combines the SearchBar component with a FlatList to create a dynamic search experience. As the user types, the list updates to show matching results, demonstrating the power and flexibility of React Native Elements.
