Happy New year notification via Flutter and OneSignal….

For all those, who wonder why not FIREBASE CONSOLE MESSAGING, please refer to this article..

Begin…

For those who have faintest idea about OneSignal, no worries you are reading the correct stuff…

https://documentation.onesignal.com/docs

Things required :

OneSignal Account if you do not already have one.
OneSignal App ID, available in Keys & IDs

Generate Credentials

Before setting up, you must generate the appropriate credentials for the platform(s) you are releasing on:

iOS — Generate an iOS Push Certificate

Android — Generate a Google Server API Key

In this article, we would look at the Android setup.

Getting Google Server API Key

Create a Firebase Project.
Get your Firebase Cloud Messaging token and Sender ID..

2.1 Click the Gear icon in the top left and select “Project settings”.

2.2 Select the “CLOUD MESSAGING” tab.

2.3 Check the red sections:

You’ll need your Server key and Sender ID.

3. Configure your OneSignal app’s Android platform settings

3.1 Go to Settings and press the Configure button to the right of Google Android.

Paste your Server Key and Sender ID in here and press Save.

Setup Android Project

https://documentation.onesignal.com/docs/android-sdk-setup

Open your app/build.gradle (Module: app) file, add the following to the very top.

Add the following to your dependencies section.

Add the following in your android > defaultConfig section.

Update PUT YOUR ONESIGNAL APP ID HERE with your OneSignal app id

nstall the flutter package….

https://pub.dartlang.org/packages/onesignal

and import 'package:onesignal/onesignal.dart';

Notifications….

Initialize OneSignal using the following code:

OneSignal.shared.init("your_app_id_here");

//in case of iOS --- see below

OneSignal.shared.init("your_app_id_here", {

OSiOSSettings.autoPrompt: false,

OSiOSSettings.inAppLaunchUrl : true

});

For Notification Receiving Handlers,

OneSignal.shared.setNotificationReceivedHandler((OSNotification notification) {

// will be called whenever a notification is received

});

and notification.jsonRepresentation() for the JSON format…

For Notification Opening Handlers,

OneSignal.shared.setNotificationOpenedHandler((OSNotificationOpenedResult result) {

// will be called whenever a notification is opened/button pressed.

});

For Creating notifications, use OSCreateNotification() and to send OneSignal.shared.postNotification(notification);

Creating Push Messages..

You need to have subscribed users before sending push messages, do that by clicking the Prompt for Push permission button in the app above

Go to OneSignal Dashboard, of your app

DASHBOARD

Click on Messages…and New Push..
