This is a library to mask Text and Input components in React Native and Expo (Android, iOS and Web).
That package is a fork of react-native-mask-text (fork) which is fork of react-native-mask-text (orignal)
The original package appears to no longer be maintained, this fork is a way to continue the project by adding features and fixes
yarn add @darlonhenrique/react-native-mask-text
Pattern used in masked components:
-
9
- accept digit. -
A
- accept alpha. -
S
- accept alphanumeric.
Ex: AAA-9999
Component similar with <TextInput />
but with custom mask option.

mask="AAA-9999"
onChangeText={(text, rawText) => {
console.log(text)
console.log(rawText)
}}
style={styles.input}
/>
//...
const styles = StyleSheet.create({
input: {
height: 40,
margin: 12,
borderWidth: 1,
},
})
