Basic Usage

• Function Component:

import React, { useState } from 'react';
import { View, Text } from 'react-native';
import { PhoneInput } from 'react-native-international-phone-number';

export default function App() {
  const [selectedCountry, setSelectedCountry] = useState(undefined);
  const [inputValue, setInputValue] = useState('');

  function handleInputValue(phoneNumber) {
    setInputValue(phoneNumber);
  }

  function handleSelectedCountry(country) {
    setSelectedCountry(country);
  }

  return (
    <View style={{ width: '100%', flex: 1, padding: 24 }}>
      <PhoneInput
        value={inputValue}
        onChangePhoneNumber={handleInputValue}
        selectedCountry={selectedCountry}
        onChangeSelectedCountry={handleSelectedCountry}
      />
      <View style={{ marginTop: 10 }}>
        <Text>
          Country:{' '}
          {`${selectedCountry?.name} (${selectedCountry?.cca2})`}
        </Text>
        <Text>
          Phone Number:{' '}
          {`${selectedCountry?.callingCode} ${inputValue}`}
        </Text>
      </View>
    </View>
  );
}

• Class Component:

import React from 'react';
import { View, Text } from 'react-native';
import { PhoneInput } from 'react-native-international-phone-number';

export class App extends React.Component {
  constructor(props) {
    super(props)
    this.state = {
      selectedCountry: undefined,
      inputValue: ''
    }
  }

  function handleSelectedCountry(country) {
    this.setState({
      selectedCountry: country
    })
  }

  function handleInputValue(phoneNumber) {
    this.setState({
      inputValue: phoneNumber
    })
  }

  render(){
    return (
      <View style={{ width: '100%', flex: 1, padding: 24 }}>
        <PhoneInput
          value={this.inputValue}
          onChangePhoneNumber={this.handleInputValue}
          selectedCountry={this.selectedCountry}
          onChangeSelectedCountry={this.handleSelectedCountry}
        />
        <View style={{ marginTop: 10 }}>
          <Text>
            Country:{' '}
            {`${this.selectedCountry?.name} (${this.selectedCountry?.cca2})`}
          </Text>
          <Text>
            Phone Number: {`${this.selectedCountry?.callingCode} ${this.inputValue}`}
          </Text>
        </View>
      </View>
    );
  }
}

Basic Usage - Typescript

import React, { useState } from 'react';
import { View, Text } from 'react-native';
import {
  PhoneInput,
  ICountry,
} from 'react-native-international-phone-number';

export default function App() {
  const [selectedCountry, setSelectedCountry] = useState<
    undefined | ICountry
  >(undefined);
  const [inputValue, setInputValue] = useState<string>('');

  function handleInputValue(phoneNumber: string) {
    setInputValue(phoneNumber);
  }

  function handleSelectedCountry(country: ICountry) {
    setSelectedCountry(country);
  }

  return (
    <View style={{ width: '100%', flex: 1, padding: 24 }}>
      <PhoneInput
        value={inputValue}
        onChangePhoneNumber={handleInputValue}
        selectedCountry={selectedCountry}
        onChangeSelectedCountry={handleSelectedCountry}
      />
      <View style={{ marginTop: 10 }}>
        <Text>
          Country:{' '}
          {`${selectedCountry?.name} (${selectedCountry?.cca2})`}
        </Text>
        <Text>
          Phone Number:{' '}
          {`${selectedCountry?.callingCode} ${inputValue}`}
        </Text>
      </View>
    </View>
  );
}

Intermediate Usage - Typescript + Default Phone Number Value

import React, { useState } from 'react';
import { View, Text } from 'react-native';
import {
  PhoneInput,
  ICountry,
} from 'react-native-international-phone-number';

export default function App() {
  const [selectedCountry, setSelectedCountry] = useState<
    undefined | ICountry
  >(undefined);
  const [inputValue, setInputValue] = useState<string>('');

  function handleInputValue(phoneNumber: string) {
    setInputValue(phoneNumber);
  }

  function handleSelectedCountry(country: ICountry) {
    setSelectedCountry(country);
  }

  return (
    <View style={{ width: '100%', flex: 1, padding: 24 }}>
      <PhoneInput
        defaultValue="+12505550199"
        value={inputValue}
        onChangePhoneNumber={handleInputValue}
        selectedCountry={selectedCountry}
        onChangeSelectedCountry={handleSelectedCountry}
      />
      <View style={{ marginTop: 10 }}>
        <Text>
          Country:{' '}
          {`${selectedCountry?.name} (${selectedCountry?.cca2})`}
        </Text>
        <Text>
          Phone Number:{' '}
          {`${selectedCountry?.callingCode} ${inputValue}`}
        </Text>
      </View>
    </View>
  );
}

Observations:

1. You need to use a default value with the following format: +(country callling code)(area code)(number phone)
2. The lib has the mechanism to set the flag and mask of the supplied defaultValue. However, if the supplied defaultValue does not match any international standard, the input mask of the defaultValue will be set to "BR" (please make sure that the default value is in the format mentioned above).

Advanced Usage - React-Hook-Form + Typescript + Default Phone Number Value

import React, { useState, useEffect } from 'react';
import { View, Text, TouchableOpacity, Alert } from 'react-native';
import {
  PhoneInput,
  ICountry,
} from 'react-native-international-phone-number';
import { Controller, FieldValues, useForm } from 'react-hook-form';

interface FormProps extends FieldValues {
  phoneNumber: string;
}

export default function App() {
  const [selectedCountry, setSelectedCountry] = useState<
    undefined | ICountry
  >(undefined);

  const { control, handleSubmit, setValue, watch } =
    useForm<FormProps>();

  function handleSelectedCountry(country: ICountry) {
    setSelectedCountry(country);
  }

  function onSubmit(form: FormProps) {
    Alert.alert(
      'Advanced Result',
      `${selectedCountry?.callingCode} ${form.phoneNumber}`
    );
  }

  useEffect(() => {
    const watchPhoneNumber = watch('phoneNumber');

    setValue('phoneNumber', watchPhoneNumber);
  }, []);

  return (
    <View style={{ width: '100%', flex: 1, padding: 24 }}>
      <Controller
        name="phoneNumber"
        control={control}
        render={({ field: { onChange, value } }) => (
          <PhoneInput
            defaultValue="+12505550199"
            value={value}
            onChangePhoneNumber={onChange}
            selectedCountry={selectedCountry}
            onChangeSelectedCountry={handleSelectedCountry}
          />
        )}
      />
      <TouchableOpacity
        style={{
          width: '100%',
          paddingVertical: 12,
          backgroundColor: '#2196F3',
          borderRadius: 4,
        }}
        onPress={handleSubmit(onSubmit)}
      >
        <Text
          style={{
            color: '#F3F3F3',
            textAlign: 'center',
            fontSize: 16,
            fontWeight: 'bold',
          }}
        >
          Submit
        </Text>
      </TouchableOpacity>
    </View>
  );
}

Observations:

1. You need to use a default value with the following format: +(country callling code)(area code)(number phone)
2. The lib has the mechanism to set the flag and mask of the supplied defaultValue. However, if the supplied defaultValue does not match any international standard, the input mask of the defaultValue will be set to "BR" (please make sure that the default value is in the format mentioned above).
