How to setup notifications in flutter application?

I was wondering if Flutter has the ability to generate push notifications from within the app. If so is there a code example of this?
Description:
An event occurs on the flutter app such as a button being clicked or an if statement being triggered, I want a push notification sent to the user.
The app should also always be running in the background, is this possible? If so can you provide me a link with an example of this implementation.
Thanks in advance for all the help!
I have looked on google but I haven't been able to find a lot of information regarding these two topics.
Being an iOS engineer, I'd say that you actually want local notifications. Push notifications are usually being sent by a server.
You could check how it's usually done on iOS natively: developer.apple.com.

iOS - Show push pop-up and play sound of the push without actual push

I want functionality in my app which will show the user how the push will look like.
So I want to show push notification and play sound from app code and even without internet connection.
Is it possible?
Does using a Local Notification help at all? This is similar to a push notification but doesn't need a server.
Other than that you can do it yousefl but you would have to do all of the drawing code!

How to create alarm through my iPhone app

I need my app to set the alarm. how can it be done without using Local Notifications as it will not work in IOS 3.0 . Please help..
Thanks in advance.
You can't. Apps pre-multiasking had to be running in the foreground all the time in order to achieve something like this.
If you have a server, then you can implement it through Apple's Push Notifications. Set the alarm by storing an entry in the server, and when it rings, have the server send the push notification. Otherwise you cannot do this without jailbreaking the phone.

Probably with push notification.

Launch iPhone app automatically when it recieves remote notification

Is it possible to launch iPhone application automatically when it receives remote notification whether it is closed or in the background? I would appreciate your help.
Thanks in advance,
Sarah
Short answer : You can't automatically launch your app when a new notification is received.
When an push notification is sent to an iPhone, the user is presented a view that is looking like an new SMS.
The user has then the option to open your application or dismiss this view.
You should check this out:
http://developer.apple.com/iphone/library/documentation/UserExperience/Conceptual/MobileHIG/HandleTasks/HandleTasks.html
and read beneath Enabling Local and Push Notifications, Here you will find an answer to your question.
Then read this:

How to implement it.
Happy Coding!
