短信未从颤振应用程序发送

Question

我正在尝试使用flutter_sms从我的flutter应用发送短信：^2.3.1。我已经实现了我在网上找到的示例中的代码。当我执行 _sendSMS() 并在观察窗口中观察 _message 时，当我在调用 _sendSMS() 后到达下一行的断点时，它会显示“正在收集数据”。我正在将消息发送到我的个人 Android 手机，但我没有收到它们。我不知道我错过了什么，所以我真的希望有人这样做并且可以帮助我。

下面是我正在使用的代码：

import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter_sms/flutter_sms.dart';


class SendTextMessage extends StatefulWidget {
  @override
  _SendTextMessageState createState() => new _SendTextMessageState();
}

class _SendTextMessageState extends State<SendTextMessage> {
  TextEditingController _controllerPeople, _controllerMessage;
  String _message, body;
  List<String> people = [];

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  Future<void> initPlatformState() async {
    _controllerPeople = TextEditingController();
    _controllerMessage = TextEditingController();
  }

  void _sendSMS(String message, List<String> recipents) async {    
    String _result =
    await sendSMS(message: message, recipients: recipents);
    _message = _result;
  }

  Widget _phoneTile(String name) {
    return Padding(
      padding: const EdgeInsets.all(3.0),
      child: Container(
          decoration: BoxDecoration(
              border: Border(
                bottom: BorderSide(color: Colors.grey[300]),
                top: BorderSide(color: Colors.grey[300]),
                left: BorderSide(color: Colors.grey[300]),
                right: BorderSide(color: Colors.grey[300]),
              )),

我改变了方法并使用了 url_launcher 工具，效果很好。
