How to pass this.state from one screen to another screen with React Native

I'm new to React Native , what I want to do is to get a this.state of screen1 for example and use it on screen2 to print this same this.state . I made a very grotesque example to try to explain:

import React, { Component } from 'react';
import {
    View,
    Text,
    StyleSheet,
    TextInput,
    TouchableHighlight,
} from 'react-native';

export default class Inputs extends Component {
    constructor(props) {
        super(props);

        this.state = {
            //Variáveis de entrada
            num1: 0,
            num2: 0,

            //Variáveis que receberão resultados
            resultadoSoma: 0,
        };

        this.calcularSoma = this.calcularSoma.bind(this);
    }

    //Cálculos
    calcularSoma() {
        let calculoSoma = 0;

        calculoSoma = parseFloat(this.state.num1) + parseFloat(this.state.num2);

        let s = this.state;
        s.resultadoSoma = calculoSoma;
        this.setState(s);
    }

    render() {
        return (
            <View>
                <TextInput
                 onChangeText={num1 => {
                     this.setState({ num1 });
                 }}/>
                <TextInput
                 onChangeText={num2 => {
                     this.setState({ num2 });
                 }}/>
                <TouchableHighlight activeOpacity={0.3} onPress={this.calcularSoma}>
                    <Text style={styles.textoBotaoContinuar}>CALCULAR</Text>
                </TouchableHighlight>

                <Text>RESULTADO: {this.state.resultadoSoma}</Text>
           </View>
        );
    }
}

How do I get this <Text>RESULTADO: {this.state.resultadoSoma}</Text> and show screen 2?

Any help will be of great value.
