React Native Paper Select - TypeScript

React Native Paper Select is a UI component library for building cross-platform mobile apps using React Native and TypeScript. It provides a simple and intuitive way to create customizable and interactive select components for your app.

Installation

To install React Native Paper Select, you need to have Node.js and npm installed on your machine. Then you can run the following command to install the package:

npm install react-native-paper-select
Usage

To use React Native Paper Select in your app, you need to import the component and render it in your code. Here is an example of how to create a simple select component:

import React, { useState } from 'react';
import { Text } from 'react-native';
import { Select } from 'react-native-paper-select';

const items = [
  { label: 'Option 1', value: 'option_1' },
  { label: 'Option 2', value: 'option_2' },
  { label: 'Option 3', value: 'option_3' },
];

const MySelect = () => {
  const [selectedItem, setSelectedItem] = useState(null);

  const handleChange = (item) => setSelectedItem(item);

  return (
    <>
      <Select
        items={items}
        label="Select an option"
        value={selectedItem}
        onValueChange={handleChange}
      />
      {selectedItem && <Text>You selected: {selectedItem.label}</Text>}
    </>
  );
};

As you can see, you can customize the select component by passing in a list of items, a label, an initial value, and a callback function to handle changes.

Customization

React Native Paper Select provides a wide range of customization options to help you style and personalize your select components. For example, you can change the color scheme, the font size, the border radius, and more. Here is an example of how to customize the select component:

import { StyleSheet } from 'react-native';

const styles = StyleSheet.create({
  select: {
    backgroundColor: '#f1f1f1',
    borderRadius: 8,
    borderWidth: 2,
    borderColor: '#ccc',
    padding: 16,
    fontSize: 18,
    color: '#333',
  },
  label: {
    marginBottom: 8,
    fontSize: 16,
    fontWeight: 'bold',
    color: '#666',
  },
});

const MySelect = () => {
  return (
    <>
      <Text style={styles.label}>Select an option:</Text>
      <Select
        items={items}
        value={selectedItem}
        onValueChange={handleChange}
        style={styles.select}
        inputProps={{ style: { fontSize: 24 } }}
        itemProps={{ labelStyle: { color: '#333' } }}
        selectedItemProps={{ labelStyle: { color: 'blue' } }}
      />
      {selectedItem && <Text>You selected: {selectedItem.label}</Text>}
    </>
  );
};

As you can see, you can customize the select component by passing in styles and props to the component and its subcomponents.

Conclusion

React Native Paper Select is a powerful and flexible library for creating select components in your React Native app. It provides a range of customization options and supports TypeScript for improved type checking and code safety.
