staticLabel : boolean

• Set this to true if you want the label to be always at a set position. Commonly used with hint for displaying both label and hint for your input. For changing the position of the label with this prop as true, use the customLabelStyles topFocused and leftFocused to adjust the wanted position. Default false.

hint : string

• Hint displays only when staticLabel prop is set to true. This prop is used to show a preview of the input to the user.

hintTextColor : string

• Set the color to the hint

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"
        value={phone}
        staticLabel
        hintTextColor={'#aaa'}
        mask="99 (99) 99999-9999"
        hint="55 (22) 98765-4321"
        containerStyles={{
          borderWidth: 2,
          paddingHorizontal: 10,
          backgroundColor: '#fff',
          borderColor: 'blue',
          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',

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 '.'.

export default app;

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}
/>;
