如何使用flutter中的任何插件将文件发送到whatsapp中的特定号码？

import 'package:flutter_share/flutter_share.dart';

void shareFileToWhatsApp(String filePath, String phoneNumber) async {
  await FlutterShare.shareFile(
    title: 'Share via WhatsApp',
    text: 'Sharing file to WhatsApp',
    filePath: filePath,
    phoneNumber: phoneNumber,
  );
}

FlatButton(
  onPressed: () {
    String filePath = '/path/to/file'; // 替换为实际文件路径
    String phoneNumber = '1234567890'; // 替换为实际WhatsApp号码
    shareFileToWhatsApp(filePath, phoneNumber);
  },
  child: Text('Share File to WhatsApp'),
),
