easy_contact_picker

Flutter 通讯录联系人选择器，同时支持Android和iOS,可以打开Native通讯录选择联系人，也可以返回通讯录列表，自己构建UI。

用法

添加这一行到pubspec.yaml

  easy_contact_picker: ^0.0.2

引用

import 'package:easy_contact_picker/easy_contact_picker.dart';

权限添加

Android

<!-- 读取联系人 -->
<uses-permission android:name="android.permission.READ_CONTACTS"/>

iOS

info.plist中添加读取通讯录权限

Privacy - Contacts Usage Description

Background Modes中 Background fetch 和 Remote notification打对勾

示例

调Native通讯录方法

Future<List<Contact>> selectContacts() async {
    final List result =
    await _channel.invokeMethod('selectContactList');
    if (result == null) {
      return null;
    }
    List<Contact> contacts = new List();
    result.forEach((f){
      contacts.add(new Contact.fromMap(f));
    });
    return contacts;
  }

返回通讯录联系人List

Future<Contact> selectContactWithNative() async {
    final Map<dynamic, dynamic> result =
    await _channel.invokeMethod('selectContactNative');
    if (result == null) {
      return null;
    }
    return new Contact.fromMap(result);
  }

需要获取权限，本示例使用的申请权限参考

 # 权限申请
  permission_handler: '^3.2.0'

权限使用方法

_openAddressBook() async{
    // 申请权限
    Map<PermissionGroup, PermissionStatus> permissions = await PermissionHandler().requestPermissions([PermissionGroup.contacts]);

    // 申请结果
    PermissionStatus permission = await PermissionHandler().checkPermissionStatus(PermissionGroup.contacts);
    //granted表示申请成功
    if (permission == PermissionStatus.granted){

    }

  }

访问Native通讯录示例

class HostPage extends StatefulWidget {
  @override
  _HostPageState createState() => _HostPageState();

}

class _HostPageState extends State<HostPage> with AutomaticKeepAliveClientMixin{

  Contact _contact = new Contact(fullName: "", phoneNumber: "");
  final EasyContactPicker _contactPicker = new EasyContactPicker();

  _openAddressBook() async{
    // 申请权限
    Map<PermissionGroup, PermissionStatus> permissions = await PermissionHandler().requestPermissions([PermissionGroup.contacts]);

    // 申请结果
    PermissionStatus permission = await PermissionHandler().checkPermissionStatus(PermissionGroup.contacts);

    if (permission == PermissionStatus.granted){
      _getContactData();
    }

  }

  _getContactData() async{
    Contact contact = await _contactPicker.selectContactWithNative();
    setState(() {
      _contact = contact;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("首页"),
      ),
      body: Column(
        children: <Widget>[
          Padding(
            padding: EdgeInsets.fromLTRB(13, 20, 13, 10),
            child: Row(
              children: <Widget>[
                Text("姓名："),
                Text(_contact.fullName)
              ],
            ),
          ),
          Padding(
            padding: EdgeInsets.fromLTRB(13, 0, 13, 20),
            child: Row(
              children: <Widget>[
                Text("手机号："),
                Text(_contact.phoneNumber)
              ],
            ),
          ),
          FlatButton(
            child: Text("打开通讯录"),
            onPressed: _openAddressBook,
          )
        ],
      ),
    );
  }

  @override
  // TODO: implement wantKeepAlive
  bool get wantKeepAlive => true;
}

获取通讯录联系人List示例

class AddressBookPage extends StatefulWidget {
  @override
  _AddressBookPageState createState() => _AddressBookPageState();
}

class _AddressBookPageState extends State<AddressBookPage> with AutomaticKeepAliveClientMixin{

  List<Contact> _list = new List();
  final EasyContactPicker _contactPicker = new EasyContactPicker();

  @override
  void initState() {
    // TODO: implement initState
    super.initState();

    _openAddressBook();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text("通讯录"),
      ),
      body: ListView.builder(
        itemBuilder: (context, index){
          return _getItemWithIndex(_list[index]);
        },
        itemCount: _list.length,
      )
    );
  }

  Widget _getItemWithIndex(Contact contact){
    return Container(
      height: 45,
      padding: EdgeInsets.only(left: 13),
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        crossAxisAlignment: CrossAxisAlignment.start,
        children: <Widget>[
          Text(contact.fullName),
          Text(contact.phoneNumber,
            style: TextStyle(
              color: Colors.grey,
            ),
          ),
        ],
      ),
    );
  }

  _openAddressBook() async{
    // 申请权限
    Map<PermissionGroup, PermissionStatus> permissions = await PermissionHandler().requestPermissions([PermissionGroup.contacts]);

    // 申请结果
    PermissionStatus permission = await PermissionHandler().checkPermissionStatus(PermissionGroup.contacts);

    if (permission == PermissionStatus.granted){
      _getContactData();
    }

  }

  _getContactData() async{
    List<Contact> list = await _contactPicker.selectContacts();
    setState(() {
      _list = list;
    });
  }

  @override
  // TODO: implement wantKeepAlive
  bool get wantKeepAlive => true;

}
