React Native Progress is a library that provides a collection of customizable progress indicators for React Native applications. It offers various types of progress components, including circular progress, bar progress, and pie progress, allowing developers to easily integrate visually appealing loading and progress indicators into their mobile apps.

Pros

• Wide variety of progress indicator types (circular, bar, pie)
• Highly customizable with props for colors, sizes, and animations
• Smooth animations and good performance
• Compatible with both iOS and Android platforms

Cons

• Limited documentation for advanced customization
• Some reported issues with TypeScript definitions
• Occasional rendering inconsistencies across different React Native versions
• Lack of frequent updates and maintenance

Code Examples

1. Basic Circle Progress

import * as Progress from 'react-native-progress';

<Progress.Circle size={50} indeterminate={true} />

This code creates a simple indeterminate circular progress indicator.

2. Bar Progress with Custom Colors

<Progress.Bar
  progress={0.7}
  width={200}
  color={'#3498db'}
  unfilledColor={'#ecf0f1'}
  borderWidth={0}
/>

This example shows a progress bar with 70% completion and custom colors.

3. Pie Progress with Animation

<Progress.Pie
  size={100}
  progress={0.4}
  animated={true}
  animationDuration={1000}
/>

This code creates an animated pie progress indicator that fills to 40% over 1 second.

Getting Started

1. Install the library:

   npm install react-native-progress
   

2. Import and use in your React Native component:

   import * as Progress from 'react-native-progress';
   
   function MyComponent() {
     return (
       <View>
         <Progress.Circle size={30} indeterminate={true} />
         <Progress.Bar progress={0.5} width={200} />
       </View>
     );
   }
