在你的组件上添加一个 props key 并且每次在你的按钮的 onPress so 组件上改变那个键每次按键更改时都会呈现如下:

Add a props key on your component and change that key every time on your button's onPress so component will render every time when key change as following :

export default function HomeScreen({ navigation }) {
  const [tempKey, setTempKey] = useState(0);
  const onPress = () => {
    //return component
    setTempKey(tempKey+1);
  };
  return (
    <View style={{ flex: 1, alignItems: "center", justifyContent: "center" }}>
      <TouchableOpacity onPress={onPress}>
        <Button title="Next word" />
      </TouchableOpacity>
      <Wordnik key={tempKey.toString()} />
    </View>
  );
}
