How about Adobe Air Vs Google Flutter?

Berton77

leokan23 Could you recommend any good learning rescources for someone who's moving from AS3 and AIR to Flutter and Dart?

Shaun_Max

Berton77 i don't think there are any tutorials specific for AS3 developers? What's available in YouTube is more than enough. It's better to start off with small projects with just features than working on making an entire app.

As shaun said, I am not sure there's a tutorial for people moving from as3/air to flutter dart. However, I totally recommend the appbrewery.co course - "Introduction to flutter development using dart". It is a great way to start. Dart is very close to as3, without all the baggage and is super modern so you will get used to it really fast. As for Flutter, it might seem a bit strange at first but if you have worked with mxml, it makes perfect sense.

Flutter's structure looks like JSON but is less readable than xml for me.

pol2095 Flutter builder so you don't have to read the UI

I don't think Flutter builder can convert mxml.

mistergreen

pol2095 I'm sure somebody can do it if they have time but probably not worth it.

leokan23

Indeed it is not worth the effort. Most components from mxml can be migrated to flutter ui super easily.

Labe -> Text
HGroup -> Row
VGroup -> Column
Group -> Container

And so on. If you need help ping me, my company has migrated a lot of Flex apps to Flutter, so at least I can point to the right direction🙂

leokan23 Does Flutter have a vector graphics API low level? Or is it just SVG loaders.

blablabla

TeotiGraphix for AS3 developer you should try StageXL instead as it was developed in the mindset of "Adobe Flash Heritage" StageXL and yes it is available in the StageXL Dart Pub

But still, if I got to migrate from AS3/AIR I personally chose Qt over Flutter.

leokan23

I am not really sure as never used / had the need for one. I know that you can load and manipulate svgs. There are also other libraries you can use for low level (an example here).

It comes down to what you need to do. In case of developing a game / flash-like type implementations (I don't recommend using flutter for games) you can use libraries like Flame (game engine) and Rive.

Wow! have you tried Qt?

blablabla

Shaun_Max yep. In Flex we have MXML in Qt we have QML. But QML is more JSON-like instead of XML-like.
The signal-slot in Qt is game changer , even someone develop it in AS3 : https://github.com/robertpenner/as3-signals

The only burden I think is the language, you got to learn C++ of course (steeper learning curve) or they now support Python.
Target platform : Windows (x86 and x64), Mac, Linux, Android, iOS , embedded and.... WASM.

So IMHO rather than Flutter , I better choose Qt coz you know learning C++ also give me greater advantages than learning Dart.

Shaun_Max

blablabla have you tried Felgo?

Shaun_Max This Felgo ? I know it but haven't tried yet.
