zalo_flutter 0.0.8

The easiest way to add Zalo login to your flutter app, get user information, profile picture and more.

A Flutter plugin for Zalo APIs.

Note: This plugin is still under development, and some APIs might not be available yet. Feedback and Pull Requests are most welcome! (Mình đang khá bận nên không có thời gian cập nhật liên tục, các bạn gặp khó khăn cứ zalo cho mình ở dưới, nếu thư viện có lỗi mong các bạn gửi mình Pull Request để mình cập nhật nhé. Cảm ơn mọi người rất nhiều.)

1. Setup

1.1 Create app Zalo

To access Zalo APIs, you'll need to make sure to create your application.

1.2 Get ZaloAppID

Then, you access to Dashboard (https://developers.zalo.me/app/[ZaloAppID]/settings). Remember your ZaloAppID

1.3 Import the package

To use this plugin, follow the plugin installation instructions.

1.4 Android integration

1. Open android/app/build.gradle and edit

minSdkVersion 21 // or bigger
compileSdkVersion 34 // or bigger
targetSdkVersion 34 // or bigger

2. Open to /android/app/src/main/AndroidManifest.xml and edit

<application
    ...
    android:name=".MyApplication">
    <activity
        ...
        android:name=".MainActivity">
        ...
    </activity>

    ...

    <!-- ZaloFlutter start -->
    <meta-data
        android:name="com.zing.zalo.zalosdk.appID"
        android:value="@string/zalo_flutter_app_id" />
    <activity
        android:name="com.zing.zalo.zalosdk.oauth.BrowserLoginActivity"
        android:exported="true">
        <intent-filter>
            <action android:name="android.intent.action.VIEW"/>
            <category android:name="android.intent.category.DEFAULT"/>
            <category android:name="android.intent.category.BROWSABLE"/>
            <data android:scheme="@string/zalo_flutter_app_id_protocol"/>
        </intent-filter>
    </activity>
    <!-- ZaloFlutter end -->
</application>
...

<!-- ZaloFlutter start -->
<queries>
    <package android:name="com.zing.zalo" />
</queries>
<!-- ZaloFlutter end -->

3. Create file strings.xml(if not exists) on folder /android/app/src/main/res/values/strings.xml. Replace with your ZaloAppID

<resources>
    <string name="zalo_flutter_app_id">[ZaloAppID]</string>
    <string name="zalo_flutter_app_id_protocol">zalo-[ZaloAppID]</string>
</resources>

4. Open file main.dart and add this widget to get HashKey

    const ZaloHashKeyAndroid(),

Then, you build app and copy HashKey

5. Open Zalo Dashboard => Login => Android (https://developers.zalo.me/app/[ZaloAppID]/login)

Paste HashKey and YourPackageName to this page and press Save

NOTE: If you upload file .aab to Google Store, it will generate another HashKey, copy it to Dashboard.

6. Add proguard for zaloSDK

-keep class com.zing.zalo.**{ *; }
-keep enum com.zing.zalo.**{ *; }
-keep interface com.zing.zalo.**{ *; }

🍄🍄🍄 Note: Phần này mình chia Kotlin và Java, tuỳ theo Project các bạn setup cho đúng nha ^^

Continue with Kotlin

• Edit the file MainActivity.kt as below. Remember YourPackageName

package [YourPackageName]

import io.flutter.embedding.android.FlutterActivity
import android.content.Intent // <-- Add this line
import com.zing.zalo.zalosdk.oauth.ZaloSDK // <-- Add this line

class MainActivity: FlutterActivity() {
    override fun onActivityResult(requestCode:Int, resultCode:Int, data: Intent) {
        super.onActivityResult(requestCode, resultCode, data)
        ZaloSDK.Instance.onActivityResult(this, requestCode, resultCode, data) // <-- Add this line
    }
}

• Create file MyApplication.kt in same folder of MainActivity.kt. Replace with your YourPackageName

package [YourPackageName]

import io.flutter.app.FlutterApplication
import io.flutter.plugin.common.PluginRegistry
import com.zing.zalo.zalosdk.oauth.ZaloSDKApplication

class MyApplication : FlutterApplication(), PluginRegistry.PluginRegistrantCallback {
    override fun onCreate() {
        super.onCreate()
        ZaloSDKApplication.wrap(this)
    }
    override fun registerWith(registry: PluginRegistry) {}
}

Continue with Java

• Edit the file MainActivity.java as below. Remember YourPackageName

package [YourPackageName];

import io.flutter.embedding.android.FlutterActivity;
import androidx.annotation.NonNull; // <-- Add this line
import io.flutter.embedding.engine.FlutterEngine; // <-- Add this line
import io.flutter.plugins.GeneratedPluginRegistrant; // <-- Add this line

import android.content.Intent; // <-- Add this line
import com.zing.zalo.zalosdk.oauth.ZaloSDK; // Add this line

public class MainActivity extends FlutterActivity {
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        ZaloSDK.Instance.onActivityResult(this, requestCode, resultCode, data); // Add this line
    }
}

• Create file MyApplication.java in same folder of MainActivity.java. Replace with your YourPackageName

package [YourPackageName]

import android.app.Application;

import com.zing.zalo.zalosdk.oauth.ZaloSDKApplication;

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        ZaloSDKApplication.wrap(this);
    }
}

iOS integration

1. Open ios/Runner/Info.plist file, edit and replace with your ZaloAppID

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	...

	<!-- ZaloFlutter start-->
	<key>CFBundleURLTypes</key>
	<array>
		<dict>
			<key>CFBundleTypeRole</key>
			<string>Editor</string>
			<key>CFBundleURLName</key>
			<string>zalo</string>
			<key>CFBundleURLSchemes</key>
			<array>
				<string>zalo-[ZaloAppID]</string>
			</array>
		</dict>
	</array>
	<key>ZaloAppID</key>
	<string>[ZaloAppID]</string>
	<key>LSApplicationQueriesSchemes</key>
	<array>
		<string>zalosdk</string>
		<string>zaloshareext</string>
	</array>
      <!-- ZaloFlutter end-->
</dict>
</plist>

2. Open ios/Runner/AppDelegate.swift file, add the following Zalo function code

import UIKit
import Flutter
import ZaloSDK // Add this line

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        GeneratedPluginRegistrant.register(with: self)
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
    // Zalo function go here
    override func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
        return ZDKApplicationDelegate.sharedInstance().application(app, open: url, options: options)
    }
}

3. Open ios/Runner.xcodeproj/project.pbxproj, search PRODUCT_BUNDLE_IDENTIFIER and copy your BundleID

4. Open Zalo Dashboard => Login => IOS (https://developers.zalo.me/app/[ZaloAppID]/login) Paste BundleID to this page and press Save

Usage

Add the following import to your Dart code:

import 'package:zalo_flutter/zalo_flutter.dart';

Functions:

• Get HashKey Android for register app in dashboard Zalo

String? data = await ZaloFlutter.getHashKeyAndroid();

• Authenticate (with app or webview)

final data = await ZaloFlutter.login(
    refreshToken: refreshToken,
);

• Log out - SDK clear oauth code in cache

await ZaloFlutter.logout();

• Validate refresh token

bool data = await ZaloFlutter.validateRefreshToken(
    refreshToken: refreshToken,
);

• Get Zalo user profile

final data = await ZaloFlutter.getUserProfile(
    accessToken: accessToken,
);
