Flutter账户选择器插件account_picker的使用

Account Picker Plugin

Flutter中的Account Picker Plugin允许用户从设备中选择保存的电子邮件或电话号码，而无需额外的权限。它是一个轻量级的插件，不需要任何特殊的设备权限。

该插件使用了AccountPicker API。目前，此功能仅支持Android平台。

Demo App

使用方法

请求电话号码

final String phone = await AccountPicker.phoneHint();
setState(() {
    _phoneNumber = phone;
});

请求电子邮件

final EmailResult emailResult = await AccountPicker.emailHint();
print(emailResult);
setState(() {
    _email = emailResult.email;
    _accountType = emailResult.type;
});

示例代码

以下是一个完整的示例应用程序，展示了如何在Flutter项目中使用account_picker插件来选择电子邮件和电话号码。

import 'dart:async';
import 'dart:io';

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

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

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String? _email;
  String? _accountType;
  String? _phoneNumber;

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

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    // Platform messages may fail, so we use a try/catch PlatformException.
    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: <Widget>[
              Text('Running on: ${Platform.operatingSystem}\n'),
              Text('Email: $_email'),
              Text('Email Type: $_accountType'),
              Text('Phone Number: $_phoneNumber'),
              ElevatedButton(
                onPressed: () async {
                  final phone = await AccountPicker.phoneHint();
                  setState(() {
                    _phoneNumber = phone;
                  });
                },
                child: Text('Pick Phone'),
              ),
              ElevatedButton(
                onPressed: () async {
                  final emailResult = await AccountPicker.emailHint();
                  print(emailResult);
                  setState(() {
                    _email = emailResult?.email;
                    _accountType = emailResult?.type;
                  });
                },
                child: Text('Pick Email'),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

当然，下面是一个关于如何在Flutter项目中使用account_picker插件的示例代码。这个插件通常用于在应用中实现账户选择器功能。首先，你需要确保你的Flutter项目已经添加了account_picker依赖。

步骤 1: 添加依赖

在你的pubspec.yaml文件中添加account_picker依赖：

dependencies:
  flutter:
    sdk: flutter
  account_picker: ^最新版本号  # 请替换为最新的版本号

然后运行flutter pub get来安装依赖。

步骤 2: 导入包

在你的Dart文件中导入account_picker包：

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

步骤 3: 使用AccountPicker

下面是一个简单的示例，展示如何在Flutter应用中使用AccountPicker：

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Account Picker Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: AccountPickerDemo(),
    );
  }
}

class AccountPickerDemo extends StatefulWidget {
  @override
  _AccountPickerDemoState createState() => _AccountPickerDemoState();
}

class _AccountPickerDemoState extends State<AccountPickerDemo> {
  List<Account> _accounts = [
    Account(
      name: 'Account 1',
      email: 'user1@example.com',
      picture: NetworkImage('https://example.com/avatar1.jpg'),
    ),
    Account(
      name: 'Account 2',
      email: 'user2@example.com',
      picture: NetworkImage('https://example.com/avatar2.jpg'),
    ),
    // 可以添加更多账户
  ];

  Account? _selectedAccount;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Account Picker Demo'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            if (_selectedAccount != null)
              ListTile(
                leading: CircleAvatar(
                  backgroundImage: _selectedAccount!.picture as NetworkImage,
                ),
                title: Text(_selectedAccount!.name),
                subtitle: Text(_selectedAccount!.email),
                trailing: IconButton(
                  icon: Icon(Icons.clear),
                  onPressed: () {
                    setState(() {
                      _selectedAccount = null;
                    });
                  },
                ),
              ),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: () async {
                final Account? result = await showAccountPicker(
                  context: context,
                  accounts: _accounts,
                  initialSelection: _selectedAccount,
                );
                if (result != null) {
                  setState(() {
                    _selectedAccount = result;
                  });
                }
              },
              child: Text('Select Account'),
            ),
          ],
        ),
      ),
    );
  }
}

class Account {
  final String name;
  final String email;
  final ImageProvider picture;

  Account({required this.name, required this.email, required this.picture});
}

说明

  1. 依赖管理：确保在pubspec.yaml中正确添加了account_picker依赖，并运行flutter pub get。
  2. 导入包：在Dart文件中导入account_picker包。
  3. 账户数据：创建一个Account类来存储账户信息，并初始化一些账户数据。
  4. UI构建：使用Scaffold、AppBar、Column、ListTile、CircleAvatar、ElevatedButton等Widget来构建UI。
  5. AccountPicker使用：调用showAccountPicker方法来显示账户选择器，并根据用户的选择更新状态。

这个示例展示了如何在Flutter应用中使用account_picker插件来实现账户选择功能。你可以根据自己的需求进一步自定义和扩展这个示例。
