fork of react-native-mask-text (with modifications)

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

Motivation

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

  onChangeText={(text, rawText) => {
    console.log(text)
    console.log(rawText)
  }}
  style={styles.input}
