react-native-mask-text v0.14.2

react-native-mask-text

This is a library to mask Text and Input components in React Native and Expo (Android, iOS and Web).

Motivation

This package was created based on other libraries of React Native text mask, with the goal of meeting the need of having a package to be used with all React Native contexts (multi-platform concept) and also be maintained currently. You can read this blog post on Substack to see more information about the creation to the current moment of this package.

Install

yarn add react-native-mask-text

Custom Mask

• 9 - accept digit.
• A - accept alpha.
• S - accept alphanumeric.

  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,
  },
});
