Question 2

react-native-progress-bar vs react-native-progress: which should I use?

Accepted Answer

react-native-progress-bar is simpler and focuses on linear animated bars, while react-native-progress offers more variety like circular and pie charts. Choose based on your need for basic animations versus advanced indicator types.

Yes, it should work with Expo since it's a pure JavaScript library with no native dependencies, but always check for compatibility with your Expo version as dependencies can change.

Accepted Answer

Update the `progress` prop in state or use the `update()` method by setting a ref on the component, as shown in the example with `setState` or direct method calls.

Question 6

Can I make the progress bar circular?

Accepted Answer

No, this library only supports linear progress bars. For circular indicators, consider alternatives like react-native-progress or custom SVG implementations.
