如何在关闭应用程序时在React Native中保存表单数据？

import AsyncStorage from '@react-native-async-storage/async-storage';

state = {
  formData: '',
};

componentDidMount() {
  this.loadFormData();
}

loadFormData = async () => {
  try {
    const formData = await AsyncStorage.getItem('formData');
    if (formData !== null) {
      this.setState({ formData });
    }
  } catch (error) {
    console.log(error);
  }
}

handleInputChange = (value) => {
  this.setState({ formData: value });
  this.saveFormData(value);
}

saveFormData = async (value) => {
  try {
    await AsyncStorage.setItem('formData', value);
  } catch (error) {
    console.log(error);
  }
}

componentWillUnmount() {
  this.clearFormData();
}

clearFormData = async () => {
  try {
    await AsyncStorage.removeItem('formData');
  } catch (error) {
    console.log(error);
  }
}
