Does Flutter have a good way to share code between mobile and web applications?

I'm looking for a good tool to develop to Web and Mobile.
A friend of mine recommended me to learn NativeScript/Angular because with that tool is possible to write the services, models, and controllers only one time and create specific views for Mobile and Web platform, sharing almost 100% the business logic code.
But I think that native script is not so hyped as flutter and maybe flutter could be more used in the next days, so I'm searching for this type of tutorial (sharing logic between Mobile and Web) in a flutter, but I'm not sure if this is really possible.
I saw something about BLOC pattern, but I am not sure if this is the correct solution for this type of project, or even if it is possible to write logic code only one time and specific "views" for Mobile and Web in a flutter.
Can anybody help me with this issue?
Thanks in advance (and sorry about my English, I'm not fluent yet)
That's the whole propaganda of flutter. The framework is made to write one code and run everywhere (android, ios, web, desktop). So you definitely are on the right path.
Unfortunately flutter web is a bit unstable right now and maybe you can face some difficulty.

Xamarin Mobile Device to SQLite stored on AWS Ec2

As the title goes, I need to connect a Xamarin built application to a SQLITE database stored inside a Amazon EC2 that is hosting a web app.
Now I agree not the most robust of set ups but i'm aware it can be done using RESTful API to build a web service and ideally host on Tomcat. But i can't find out how. Totally new to APIs.
That's all I need really. I've been down most avenues of Google and Xamarin support docs. But I really need someone to point me in the right direction as im seeing alot of broken links for Xamarin docs that revert me to Microsofts site. Or help find an example, anything would be heavily appreciated. I can only offer that if you answer my question you will make someones day and I will post a cute picture of a hamster.
Thanks!

Connecting an Ionic app to an existing database

I have an existing database that I want to connect to an Ionic app I've made. Ive seen people recommend Silex to make a RESTful api but I have no idea how to do so, and the tutorials I've seen use new apps, not existing ones. I just want to be pointed in the right direction since its all a little overwhelming. Thanks in advance!

Server Setup for iPhone Push Notifications

I'm new to the whole push notifications thing, and was wondering if somebody could walk me through the process of getting a simple application up and running. I currently rent a server that I use to serve my website that runs cPanel X.
How would I go about setting up the service? What software do I need to install on the server? How do I upload code to the server?
Sorry if these are really dumb questions - I'm not really a web developer.
Thanks in advance!
I would go to the Apple Developer Forums. They have many questions and answers regarding this. For my apps, I use a Ruby On Rails plugin called apn_on_rails, but this is probably not an option for you on a shared host with some sort of admin gui. Your shared host probably runs php so I would look for a php implementation.

Where should I start with a facebook application?

I am thinking about developing a fairly simple facebook application which i have modelled the database in access.
I have web space and mySQL databases available, but I was wondering if anyone could point me towards any guides for facebook development? I had a search a while back, but they all seemed rather out of date. Anyone know where I should start with this?
I don't want to really share exactly what my idea is, but its a rating system for a particular set of products.
I haven't done much PHP before, only edited my wordpress template, and I do know enough SQL I hope.

No need to go through a bunch of small tutorials when you can find out just about all you can do through this book. It seems to be lacking on building a facebook app with an iframe though.
