我正在创建一个项目，我从具有电话号码的客户模型中引入数据，并且我需要能够将该电话号码添加为新联系人，但我还没有找到重定向我的方法应用程序添加联系人。我只看到了如何重定向呼叫。

Padding(
 padding: const EdgeInsets.only(left: 10.0),
 child: Container(
  width: 50,
  child: FlatButton(
   child: Icon(Icons.call, color: Color(0xFF7AAF00),),
   onPressed:() async
   String url = 'tel:$model.cliente.telefono'; 
   if (await canLaunch(url)) 
    await launch(url);
   else
    throw 'No se pudo $url';
   
  
 ),
),),


Container(
width: 50,
child: FlatButton(
 child: Icon(Icons.contact_page_outlined, color: Color(0xFF7AAF00),),
  onPressed: ()
  ,
),),

【参考方案1】：

要使用 Flutter 向您的手机添加新联系人，我建议使用来自 pub dev 的包

Klick here to view flutter_contact package

这个包有一个函数叫做：

等待 Contacts.addContact(newContact);

取决于您的目标等。 这是包中的完整示例：

import 'package:flutter/material.dart';
import 'package:flutter/widgets.dart';
import 'package:flutter_contact/contacts.dart';
import 'package:flutter_contact/flutter_contact.dart';

class AddContactPage extends StatefulWidget 
  @override
  State<StatefulWidget> createState() => _AddContactPageState();


class _AddContactPageState extends State<AddContactPage> 
  Contact contact = Contact();
  PostalAddress address = PostalAddress(label: 'Home');
  final _formKey = GlobalKey<FormState>();

  @override
  Widget build(BuildContext context) 
    return Scaffold(
      appBar: AppBar(
        title: Text('Add a contact'),
        actions: <Widget>[
          TextButton(
            onPressed: () 
              _formKey.currentState!.save();
              contact.postalAddresses = [address];
              Contacts.addContact(contact);
              Navigator.of(context).pop();
            ,
            child: Icon(Icons.save, color: Colors.white),
          )
        ],
      ),
      body: Container(
        padding: EdgeInsets.all(12.0),
        child: Form(
          key: _formKey,
          child: ListView(
            children: <Widget>[
              TextFormField(
                decoration: const InputDecoration(labelText: 'First name'),
                onSaved: (v) => contact.givenName = v,
              ),
