Getting Started

iOS

1. You will need notification permission so add this to your ios/Podfile

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)

    target.build_configurations.each do |config|
       config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',
        # dart: PermissionGroup.notification
        'PERMISSION_NOTIFICATIONS=1',
      ]
    end
  end
end

2. Add this to your `ios/AppDelegate.swift'

.
.
import UserNotifications
import notification_when_app_is_killed

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
   override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {

    if #available(iOS 10.0, *) {
        UNUserNotificationCenter.current().delegate = self as UNUserNotificationCenterDelegate
    }

   .
   .
   .
  }

  override func applicationWillTerminate(_ application: UIApplication) {
    let notificationWhenAppIsKilledInstance = NotificationWhenAppIsKilledPlugin.instance
    notificationWhenAppIsKilledInstance.applicationWillTerminate();
  }
}

see example AppDelegate.swift

How to use

setNotificationOnKillService:

final _notificationWhenAppIsKilledPlugin = NotificationWhenAppIsKilled();

ArgsForIos argsForIos = ArgsForIos(
  interruptionLevel: InterruptionLevel.critical,
  useDefaultSound: true,
);
await _notificationWhenAppIsKilledPlugin.setNotificationOnKillService(
  ArgsForKillNotification(
      title: 'The app is killed',
      description:
          'You can see this notification when the app is killed',
      argsForIos: argsForIos),
)

cancelNotificationOnKill:

final _notificationWhenAppIsKilledPlugin = NotificationWhenAppIsKilled();

await _notificationWhenAppIsKilledPlugin
              .cancelNotificationOnKillService()
)

notification_when_app_is_killed's Issues

Example on Android device

Hi.
First of all thanks for developing this package.
I run the example code on android device but nothing happening.

It doesn't work in Android

This works fine in iOS, but doesn't work in Android (I use the example project you provided).

No sound or vibration for notification on IOS

how does this work?

what does this do exactly and how do i get a notification?
