如何在没有状态的情况下实现TextInput [React-native]

import React, { Component } from 'react';
import { TextInput } from 'react-native';

class MyTextInput extends Component {
  constructor(props) {
    super(props);
    this.state = {
      text: ''
    };
  }

  onChangeText = (text) => {
    this.setState({ text });
  }

  render() {
    return (
      <TextInput
        value={this.state.text}
        onChangeText={this.onChangeText}
      />
    );
  }
}

export default MyTextInput;

import React, { Component, createRef } from 'react';
import { TextInput } from 'react-native';

class MyTextInput extends Component {
  constructor(props) {
    super(props);
    this.textInputRef = createRef();
  }

  getText = () => {
    const text = this.textInputRef.current.value;
    console.log(text);
  }

  render() {
    return (
      <TextInput
        ref={this.textInputRef}
      />
    );
  }
}

export default MyTextInput;
