Question

我一直被这个问题困扰。如何从flutter中的联系人中选择和获取详细信息？请帮忙。

Answer 1

withcontacts_service：^ 0.2.5，您可以通过添加查询进行搜索，但是如果您有任何想法，我没有通过电话或电子邮件找到。

https://pub.dev/packages/contacts_service#-readme-tab-

Iterable<Contact> johns = await ContactsService.getContacts(query : "john");

Answer 2

添加此依赖项

这是当前版本

contact_picker：^ 0.0.2

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

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

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

 class _MyAppState extends State<MyApp> {
  final ContactPicker _contactPicker = new ContactPicker();
  Contact _contact;

  @override
  Widget build(BuildContext context) {
   return new MaterialApp(
   home: new Scaffold(
    appBar: new AppBar(
       title: new Text('Plugin example app'),
     ),
      body: new Center(
      child: new Column(
        mainAxisSize: MainAxisSize.min,
         children: <Widget>[
          new MaterialButton(
            color: Colors.blue,
            child: new Text("CLICK ME"),
            onPressed: () async {
              Contact contact = await _contactPicker.selectContact();
              setState(() {
                _contact = contact;
              });
            },
          ),
          new Text(
            _contact == null ? 'No contact selected.' : _contact.toString(),
          ),
        ],
      ),
    ),
  ),
);
 }
}

Answer 3

使用contact_picker: ^0.0.2获取联系人

在您的pubspec.yaml文件中添加依赖项

dependencies:
  flutter:
    sdk: flutter

  contact_picker: ^0.0.2

将其导入您要使用的位置并创建一个openContactBook（）函数

import 'package:contact_picker/contact_picker.dart';


Future<String> openContactBook() async {
  Contact contact = await _contactPicker.selectContact();
  if (contact != null) {
    var phoneNumber = contact.phoneNumber.number.toString().replaceAll(new RegExp(r"\s+"), "");
    return phoneNumber;
  }
  return "";
}

像这样使用它

onPressed: () {
  var contactNumber = openContactBook()
}
