我正在尝试使用React-Native在屏幕底部放置按钮，我真的很难理解如何正确地使用flex支持

import React from 'react';
import { View, Button } from 'react-native';

const App = () => {
  return (
    <View style={{ flex: 1 }}>
      {/* 其他内容 */}
      <Button title="底部按钮" onPress={() => console.log('按钮被点击')} />
    </View>
  );
};

export default App;

import React from 'react';
import { View, Button } from 'react-native';

const App = () => {
  return (
    <View style={{ flex: 1 }}>
      {/* 其他内容 */}
      <View style={{ position: 'absolute', bottom: 0 }}>
        <Button title="底部按钮" onPress={() => console.log('按钮被点击')} />
      </View>
    </View>
  );
};

export default App;
