Question 1

How to style react-native-confirmation-code-field?

Accepted Answer

Use the renderCell prop to apply custom styles per cell, as shown in the basic example—you'll need to define CSS for borders, colors, and focus states manually. The README provides examples like underline and animated variants for reference.

Question 2

Does react-native-confirmation-code-field support SMS auto-fill on Android?

Accepted Answer

Yes, but it requires manual configuration: set autoComplete to 'sms-otp' on Android, as highlighted in the platform-specific code snippet. This ensures proper integration with system-level SMS paste features.

Question 3

react-native-confirmation-code-field vs react-native-otp-textfield: which is better?

Accepted Answer

retyui's library is lighter (3.8 KB) and more customizable, ideal for tailored UI, while react-native-otp-textfield offers more out-of-the-box styles. Choose based on whether you prioritize minimal size and flexibility over pre-built designs.

Question 4

Can I use this with React 18?

Accepted Answer

Only with version 8.x.x, as the README states React 19 is required for the latest release. This forces a downgrade or upgrade, potentially missing new features or fixes.

Question 5

How to handle validation with react-native-confirmation-code-field?

Accepted Answer

You must implement validation externally using useState or form libraries—the component only manages input state. Check the value prop in onChangeText to add logic for invalid codes or length requirements.

Question 6

Is it compatible with Expo?

Accepted Answer

Yes, the README includes a live Expo app link, confirming it works in Expo environments. No native module installation is needed, making it straightforward for Expo projects.
