flutter_push_notifications 0.0.1

Flutter push notifications

flutter_push_notifications

The goal of this plugin is to make it easy to execute actions directly from PUSH notifications.

Sample uses for this plugin are:

• Accepting/Rejecting a work offer, sent as PUSH notification

• Reporting an assignment with defaults when you get a notification that assignment has finished

• Sending a confirmation that you received 15 assignments that were assigned to you

• Replying to a message directly from a widget when you get a message as PUSH notification

Usage

To use this plugin, add flutter_push_notifications as a dependency in your pubspec.yaml file.

Getting Started

Check out the example directory for a sample app using

Android Integration

To integrate your plugin into the Android part of your app, follow these steps:

1. Add the classpath to the [project]/android/build.gradle file.

dependencies {
  // Example existing classpath
  classpath 'com.android.tools.build:gradle:3.5.0'
  // Add the google services classpath
  classpath 'com.google.gms:google-services:4.3.3'
}

2. Add the apply plugin to the [project]/android/app/build.gradle file.

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

iOS Integration

1. Generate the certificates required by Apple for receiving push notifications following this guide in the Firebase docs. You can skip the section titled "Create the Provisioning Profile".

2. In Xcode, select Runner in the Project Navigator. In the Capabilities Tab turn on Push Notifications and Background Modes, and enable Background fetch and Remote notifications under Background Modes.

3. Follow the steps in the "Upload your APNs certificate" section of the Firebase docs.

4. If you need to disable the method swizzling done by the FCM iOS SDK (e.g. so that you can use this plugin with other notification plugins) then add the following to your application's Info.plist file.

<key>FirebaseAppDelegateProxyEnabled</key>
<false/>

After that, add the following lines to the (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method in the AppDelegate.m of your iOS project

  [UNUserNotificationCenter currentNotificationCenter].delegate = (id<UNUserNotificationCenterDelegate>) self;
}

Dart/Flutter Integration

From your Dart code, you need to import the plugin and instantiate it:

import 'package:flutter_push_notifications/flutter_push_notifications.dart';

final FlutterPushNotifications _flutterPushNotifications = FlutterPushNotifications();

Next, you should probably request permissions for receiving Push Notifications. For this, call _flutterPushNotifications.requestNotificationPermissions(). This will bring up a permissions dialog for the user to confirm on iOS. It's a no-op on Android.

To get firebase token use:

 _flutterPushNotifications.getToken().then((token) { });

For get data from clicked notification action use:

 _flutterPushNotifications.onPushPress.listen((message) { });

example sending data from firebase:

{ 
  "notification": {
    "title": "Työvuorosi on päättynyt",
    "text": "15.1. 8:00 - 16:00 Some great assignment",
    "click_action":"NOTIFICATION_CATEGORY"
  },
	"to" : "DEVICE_TOKEN",
  "data": {
    "data": {
      "route": "/assignments/123456"
    }
  }
}

Each NOTIFICATION_CATEGORY associated with the list of NotificationAction.

NotificationAction class allows you to set visible title of action, behavior and activation mode. By default push notification will activate the app and action will have "clickable" behavior. The "behavior" can be "default" which means action will have just "clickable" behavior and also can be "textInput" which means action will be presented as text input. The "activationMode" can be "foreground" and "background". "Foreground" activation mode will open the app and you can process the data in the app. "Background" activation mode allows you to process the data in the background.

class NotificationAction {
  String title;
  String identifier;
  /// foreground, background
  String activationMode;
  /// default, textInput
  String behavior;

  ...
}

NotificationCategory class accepts identifier and list of actions which are associated with this category:

class NotificationCategory {
  String identifier;
  List<NotificationAction> actions;

  ...
}

Example of creating categories with the list of actions:

List<NotificationAction> viewActions = List<NotificationAction>();
NotificationAction action1 = NotificationAction(
  title: 'First title',
  identifier: 'FIRST_ACTION'
);
viewActions.add(action1);
NotificationAction action2 = NotificationAction(
    title: 'Second title',
    identifier: 'SECOND_ACTION'
);
viewActions.add(action2);
NotificationCategory firstCategory = NotificationCategory('FIRST_CATEGORY', viewActions);
List<NotificationAction> sendActions = List<NotificationAction>();
NotificationAction sendAction = NotificationAction(
  title: 'Text input action',
  identifier: 'TEXT_INPUT_ACTION',
  behavior: 'textInput'
);
sendActions.add(sendAction)
NotificationCategory secondCategory = NotificationCategory('SECOND_CATEGORY', sendActions);

Finally you should register your categories:

_flutterPushNotifications.registerNotificationCategory([firstCategory, secondCategory]);
