import React, { useState } from 'react';
import { View } from 'react-native';
import { FloatingLabelInput } from 'react-native-floating-label-input';

const app: React.FC = () => {
  const [phone, setPhone] = useState('');

  return (
    <View style={{ padding: 50, flex: 1, backgroundColor: '#fff' }}>
      <FloatingLabelInput
        label="Phone"

        staticLabel
        hintTextColor={'#aaa'}
        mask="99 (99) 99999-9999"
        hint="55 (22) 98765-4321"

          borderWidth: 2,
          paddingHorizontal: 10,
          backgroundColor: '#fff',

          borderRadius: 8,
        }}
        customLabelStyles={{
          colorFocused: 'red',
          fontSizeFocused: 12,
        }}
        labelStyles={{
          backgroundColor: '#fff',
          paddingHorizontal: 5,
        }}
        inputStyles={{
          color: 'blue',
          paddingHorizontal: 10,
        }}
        onChangeText={value => {
          setPhone(value);
        }}
      />
    </View>
  );
};
export default app;

setGlobalStyles : Object

// index.js or any other root file
import { AppRegistry } from 'react-native';
import App from './App';
import { name as appName } from './app.json';
import './globalStyles';

AppRegistry.registerComponent(appName, () => App);

// globalStyles.js
import { setGlobalStyles } from 'react-native-floating-label-input';

setGlobalStyles.containerStyles = {
  backgroundColor: '#eeddee',
  // any styles you want to generalize to your input container
};
setGlobalStyles.labelStyles = {
  color: '#f98f68',
  // any styles you want to generalize to your floating label
};
setGlobalStyles.inputStyles = {
  color: '#383',
  // any styles you want to generalize to your input
};

Input mask

Props relating mask:

  • mask: 'string';
  • maskType?: 'currency' | 'phone' | 'date' | 'card';
  • currencyDivider: ',' | '.';
  • Currency

    Currently the mask will take effect in all maskTypes, except 'currency', wich is made automatically when maskType is set as currency. The reason is because currency is dynamic within the input value. If you want to change the thousands divider to other pattern, just insert the prop currencyDivider with one of: ',' or '.'.

customShowPasswordImage or customHidePasswordImage

  • If you want to use the "customShowPasswordImage" prop or "customHidePasswordImage" prop, provide a image path, for example:
import showPassword from '../assets/images/yourImage';
import hidePassword from '../assets/images/yourImage2';
// ...
<FloatingLabelInput
  label="Password"
  value={password}
  isPassword={true}
  onChangeText={text => setPassword(text)}
  customShowPasswordImage={showPassword}
  customHidePasswordImage={hidePassword}
/>;
