Flutter电话功能插件simple_telephony的使用

当然，以下是如何在Flutter项目中使用simple_telephony插件来实现基本电话功能的示例代码。simple_telephony插件允许你获取设备的电话信息、监听来电和去电等。

首先，确保你已经在pubspec.yaml文件中添加了simple_telephony依赖：

dependencies:
  flutter:
    sdk: flutter
  simple_telephony: ^x.y.z  # 请替换为最新版本号

然后，运行flutter pub get来安装依赖。

接下来，在你的Flutter项目中，你可以按照以下步骤使用simple_telephony插件：

1. 导入插件：

import 'package:simple_telephony/simple_telephony.dart';

1. 初始化插件并获取电话信息：

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  late SimpleTelephony _telephony;
  String? _imei;
  String? _imeiSv;
  String? _imsi;
  String? _mcc;
  String? _mnc;
  String? _line1Number;
  String? _networkOperator;
  String? _networkOperatorName;
  String? _networkType;
  String? _phoneNumber;
  String? _simState;
  String? _subscriberId;
  String? _voiceMailNumber;

  @override
  void initState() {
    super.initState();
    _telephony = SimpleTelephony();

    // 获取设备信息
    _telephony.getIMEI().then((imei) => setState(() => _imei = imei));
    _telephony.getIMEISV().then((imeiSv) => setState(() => _imeiSv = imeiSv));
    _telephony.getIMSI().then((imsi) => setState(() => _imsi = imsi));
    _telephony.getMCC().then((mcc) => setState(() => _mcc = mcc));
    _telephony.getMNC().then((mnc) => setState(() => _mnc = mnc));
    _telephony.getLine1Number().then((line1Number) => setState(() => _line1Number = line1Number));
    _telephony.getNetworkOperator().then((networkOperator) => setState(() => _networkOperator = networkOperator));
    _telephony.getNetworkOperatorName().then((networkOperatorName) => setState(() => _networkOperatorName = networkOperatorName));
    _telephony.getNetworkType().then((networkType) => setState(() => _networkType = networkType));
    _telephony.getPhoneNumber().then((phoneNumber) => setState(() => _phoneNumber = phoneNumber));
    _telephony.getSimState().then((simState) => setState(() => _simState = simState));
    _telephony.getSubscriberId().then((subscriberId) => setState(() => _subscriberId = subscriberId));
    _telephony.getVoiceMailNumber().then((voiceMailNumber) => setState(() => _voiceMailNumber = voiceMailNumber));
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Telephony Info'),
        ),
        body: Padding(
          padding: const EdgeInsets.all(16.0),
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: <Widget>[
              Text('IMEI: $_imei'),
              Text('IMEI SV: $_imeiSv'),
              Text('IMSI: $_imsi'),
              Text('MCC: $_mcc'),
              Text('MNC: $_mnc'),
              Text('Line 1 Number: $_line1Number'),
              Text('Network Operator: $_networkOperator'),
              Text('Network Operator Name: $_networkOperatorName'),
              Text('Network Type: $_networkType'),
              Text('Phone Number: $_phoneNumber'),
              Text('SIM State: $_simState'),
              Text('Subscriber ID: $_subscriberId'),
              Text('Voice Mail Number: $_voiceMailNumber'),
            ],
          ),
        ),
      ),
    );
  }
}

1. 监听来电和去电：

为了监听来电和去电，你可以使用SimpleTelephony的listenIncomingCall和listenOutgoingCall方法。以下是如何实现监听功能的示例：

@override
void initState() {
  super.initState();
  _telephony = SimpleTelephony();

  // 监听来电
  _telephony.listenIncomingCall().listen((Call call) {
    print('Incoming Call: ${call.number}');
    // 你可以在这里添加更多逻辑来处理来电，比如显示UI提示等
  });

  // 监听去电
  _telephony.listenOutgoingCall().listen((Call call) {
    print('Outgoing Call: ${call.number}');
    // 你可以在这里添加更多逻辑来处理去电，比如显示UI提示等
  });

  // ... 其他初始化代码 ...
}

请注意，simple_telephony插件的API可能会随着版本的更新而发生变化，因此请参考插件的官方文档以获取最新的API信息和使用指南。

以上代码提供了一个基本的使用示例，展示了如何获取设备的电话信息和监听来电、去电事件。你可以根据自己的需求进一步扩展和定制这些功能。
