Example

Here is a complete example of how to use the flutter_phone_dialer plugin in a Flutter app.

Example Code

import 'package:flutter/material.dart';
import 'package:flutter_phone_dialer/flutter_phone_dialer.dart';

void main() => runApp(const MyApp());

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final TextEditingController _numberCtrl = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Dialer Example'),
        ),
        body: Column(
          children: <Widget>[
            Padding(
              padding: const EdgeInsets.all(8.0),
              child: TextField(
                controller: _numberCtrl,
                decoration: const InputDecoration(labelText: "Phone Number"),
                keyboardType: TextInputType.number,
              ),
            ),
            ElevatedButton(
              child: const Text("Call"),
              onPressed: () async {
                FlutterPhoneDialer.dialNumber(_numberCtrl.text);
              },
            ),
          ],
        ),
      ),
    );
  }

  @override
  void initState() {
    super.initState();
    _numberCtrl.text = "*400#"; // Default number
  }
}

Explanation

  1. Import the Package: Import the flutter_phone_dialer package.
  2. Create a Text Field: Use a TextField to allow users to input the phone number.
  3. Create a Button: Use an ElevatedButton to trigger the dialing action.
  4. Dial the Number: When the button is pressed, call the dialNumber method from the FlutterPhoneDialer class with the phone number entered by the user.

This example demonstrates a simple way to integrate phone number dialing into your Flutter application using the flutter_phone_dialer plugin.

当然，下面是一个关于如何在Flutter应用中使用flutter_phone_dialer插件来拨打电话的示例代码。这个插件允许你的应用程序调用设备的电话拨号界面。

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

dependencies:
  flutter:
    sdk: flutter
  flutter_phone_dialer: ^2.0.0  # 请检查最新版本号

然后，运行flutter pub get来安装依赖项。

接下来，在你的Flutter应用中，你需要导入flutter_phone_dialer包，并请求必要的权限（拨打电话的权限）。下面是一个完整的示例，展示了如何使用这个插件：

import 'package:flutter/material.dart';
import 'package:flutter_phone_dialer/flutter_phone_dialer.dart';
import 'package:permission_handler/permission_handler.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter Phone Dialer Example'),
        ),
        body: Center(
          child: DialPhoneButton(),
        ),
      ),
    );
  }
}

class DialPhoneButton extends StatefulWidget {
  @override
  _DialPhoneButtonState createState() => _DialPhoneButtonState();
}

class _DialPhoneButtonState extends State<DialPhoneButton> {
  bool hasPermission = false;

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

  Future<void> _requestPermission() async {
    // 请求拨打电话的权限
    var status = await Permission.phone.status;

    if (!status.isGranted) {
      var result = await Permission.phone.request();
      if (result.isGranted) {
        setState(() {
          hasPermission = true;
        });
      }
    } else {
      setState(() {
        hasPermission = true;
      });
    }
  }

  Future<void> _dialPhoneNumber(String phoneNumber) async {
    if (await FlutterPhoneDialer.canOpenUrl(phoneNumber)) {
      await FlutterPhoneDialer.openPhoneNumber(phoneNumber,
          androidLaunchFlags: [
            FlutterPhoneDialerAndroidLaunchFlags.CLEAR_TASK,
            FlutterPhoneDialerAndroidLaunchFlags.NEW_TASK
          ]);
    } else {
      // 如果无法拨打电话，则显示一个错误消息
      ScaffoldMessenger.of(context).showSnackBar(
        SnackBar(content: Text('无法拨打电话，请检查您的设置。')),
      );
    }
  }

  @override
  Widget build(BuildContext context) {
    return ElevatedButton(
      onPressed: hasPermission
          ? () => _dialPhoneNumber('1234567890')  // 替换为你想要拨打的电话号码
          : null,
      child: Text('拨打电话'),
    );
  }
}

说明：

  1. 权限请求：

    • 使用permission_handler包来请求拨打电话的权限。
    • 在initState方法中调用_requestPermission方法来请求权限。

  2. 拨打电话：

    • _dialPhoneNumber方法检查是否可以打开电话拨号界面，如果可以，则调用FlutterPhoneDialer.openPhoneNumber方法。
    • 如果无法拨打电话，则显示一个SnackBar错误消息。

  3. UI：

    • 使用ElevatedButton来创建一个按钮，当用户点击按钮时，如果已获得权限，则拨打指定的电话号码。

请确保在实际部署前测试代码，并根据需要进行调整。此外，别忘了在AndroidManifest.xml和Info.plist中添加必要的权限声明，以便应用能够请求拨打电话的权限。
