Unfocus a TextInput in React Native

I'm building an Android app with React Native.

How can you force a TextInput to "unFocus", meaning the cursor is blinking inside the text field. There are functions for isFocused() and onFocus(), but how do I actually get the text field to give up focus. You would think it does so automatically once I hit enter, but that's not the case.

   import React, {Component} from 'react';   import { AppRegistry, Text, View, StyleSheet, TextInput, TouchableOpacity}    from 'react-native';   var SHA256 = require("crypto-js/sha256");   export default class LoginForm extends Component{constructor(props){    super(props);    this.state = {        email: '',        password:''    };}tryLogin = () => {    if(this.state.email=="email123"&& this.state.password == "password"){        console.log("password verified");        this.props.navigator.replace({            title: 'Dashboard'        });    }    console.log(this.state.email);    console.log(this.state.password);    console.log("Hash"+ SHA256(this.state.password));}render(){    return(<View style={styles.container}><TextInput                 style={styles.input}                placeholder="Email address"                placeholderTextColor="white"                onChangeText={(email) => this.setState({email})}></TextInput><TextInput style={styles.input}                 placeholder="Password"                placeholderTextColor="white"                secureTextEntry                onChangeText={(password) => this.setState({password})}></TextInput><TouchableOpacity style={styles.loginButtonContainer} onPress={this.tryLogin}><Text style={styles.loginButtonText}>LOGIN</Text></TouchableOpacity></View>  );}}AppRegistry.registerComponent('LoginForm', () => LoginForm);const styles =  StyleSheet.create({container: {    padding: 20},input:{    height: 40,    backgroundColor: '#e74c3c',    marginBottom: 20,    color: 'white',    paddingHorizontal: 15,    opacity: .9},loginButtonContainer:{    justifyContent: 'center',    backgroundColor: '#bc4c3c',    paddingVertical:15},loginButtonText:{    textAlign:'center',    color:'white',    fontWeight: '700',    fontSize: 24}   })

This probably won't matter as much for real users but I'm just emulating and its pesky if I want to reload.
