vk_login

A Flutter package for authorization via VK.

Usage

Add vk_login as a dependency in your pubspec.yaml file. If you are targeting Android, make sure to read the Android Platform Views section below to choose the platform view mode that best suits your needs.

Getting Started

1. Set the correct minSdkVersion in android/app/build.gradle (if it was previously lower than 19):

android {
    defaultConfig {
        minSdkVersion 19
    }
}

2. Add android:usesCleartextTraffic="true" in your AndroidManifest.xml

<manifest ...>
   <application
        android:label="label"
        android:icon="@mipmap/ic_launcher"
        android:usesCleartextTraffic="true">

Example in application

You need to wrap your MaterialApp with ChangeNotifierProvider

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import 'package:vk_login/vk_login.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider(
      create: (_) => VkProvider(),
      child: MaterialApp(
        title: 'Material App',
        home: Scaffold(
          appBar: AppBar(
            title: Text('Material App Bar'),
          ),
          body: HomePage(),
        ),
      ),
    );
  }
}

First you must to call init()

class HomePage extends StatelessWidget {
  late VkProvider _vk;

  @override
  Widget build(BuildContext context) {
    _vk = Provider.of<VkProvider>(context);
    return FutureBuilder(
        future: _vk.init(),
        builder: (context, snapshot) {
          if (snapshot.connectionState == ConnectionState.waiting)
            return Center(
              child: Text('Loading...'),
            );
          return Column(
            children: [
              TextButton(
                  onPressed: () => _vk.login(context,
                      permissions: [VKScope.stats, VKScope.groups, VKScope.messages, VKScope.wall, VKScope.offline]),
                  child: Text('login')),
              TextButton(onPressed: () => _vk.logout(), child: Text('logout')),
              if (_vk.profile != null) Text('${_vk.profile!.firstName}'),
            ],
          );
        });
  }
}
