Upgrading to React Native SDK v2


Version 2 and above of our React Native SDK depends on AndroidX and therefore needs React Native 0.60+

Upgrade your dependency

npm install react-native-wonderpush@2

Android-specific changes

minSdkVersion changes

We have raised the required minSdkVersion to 21, released in 2014 and covers 95% of Android devices.

Make sure your application uses at least 21 in your android/build.gradle, otherwise you'll see the following build error:

Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [com.wonderpush:wonderpush-android-sdk:4.0.1] [...]/.gradle/caches/transforms-2/files-2.1/110f18d74c064672b3bb9b02e46b3f51/jetified-wonderpush-android-sdk-4.0.1/AndroidManifest.xml as the library might be using APIs not available in 16
	Suggestion: use a compatible library with a minSdk of at most 16,
		or increase this project's minSdk version to at least 21,
		or use tools:overrideLibrary="com.wonderpush.sdk" to force usage (may lead to runtime failures)

Add the explicit dependency on our FCM compatibility module

npm add react-native-wonderpush-fcm
react-native link react-native-wonderpush-fcm

iOS-specific changes

Upgrade your Notification Service Extension

Open ios/Podfile and replace:

pod 'WonderPushExtension', '~> 3.0'

with that:

pod 'WonderPushExtension', '~> 4.0'


Please close Xcode before proceeding

Open a Terminal window in your flutter project directory and type:

cd ios
pod install

Provide your clientId and clientSecret to your Notification Service Extension. Find your ios/WonderPushNotificationServiceExtension/NotificationService.swift file and override the following two methods:

import WonderPushExtension

class NotificationService: WPNotificationServiceExtension {

    override class func clientId() -> String {
        return "YOUR_CLIENT_ID"

    override class func clientSecret() -> String {
        return "YOUR_CLIENT_SECRET"

#import "NotificationService.h"

@implementation NotificationService

+ (NSString *)clientId {
    return @"YOUR_CLIENT_ID";


+ (NSString *)clientSecret {
    return @"YOUR_CLIENT_SECRET";


Make sure to give the same values as in your AppDelegate.

React Native code changes

Remove calls to deprecated APIs

Remove any calls to WonderPush.isReady().
You do not need to wait to use WonderPush.


You're done!
