Learn Swift+iOS & Kotlin/Java+Android then Dart/Flutter. How many lifetimes is that to become deeply proficient?

I do consulting across Java, Android, .NET, C++ and Web stacks. I am a Language X expert that knows every little detail, surely no. Am I proficient enough to keep costumers happy with the results and willing to keep assignments for new stuff coming my way? You bet.

The second sentence doesn't quite make sense to me. Are you saying you hire yourself out to customers as an expert in Java, .Net, C++ & web stack but with only enough detail to produce work that keeps them happy?

Yes, in a way that is it, just I haven't stated that I am an expert, rather that I know them well enough to deliver quality work.

Most companies don't have software as their core business, they just want something that works for their business case, and most of the time they even value more domain knowledge and social skills than beautiful technical solutions.

If it works, fulfils the SLAs and the internal teams are happy with the delivery acceptance review, that is all that matters.

Here is some info: https://flutter.io/faq/#how-big-is-the-flutter-engine

in summary : a minimal UI app goes from 40k of java code to 6700k of compressed dart code

Not compressed, compiled to machine code.

I think whats adding to the confusion here is the "I am a Language X expert". I suspect the Am and I need to be interchanged there.

You are right, I got that part wrong.

I am surely not a language expert.

I'm evaluating it. Why do you think it's the future? What's the feature you value most?

I've been a React fanatic for several years, so my opinion is colored by that: 1. Great DX (developer experience) - a single language (Dart); no need for JSX, JavaScript, JSON, Flux/Redux and various other libraries. You can focus on the business logic rather than battling the ecosystem. 2. A single set of components (no iOS or Android specific navigator components etc.) 3. No longer need a JS engine to run - truly n…

I view the absence of JSX as a liability. I like flutter, but I find a lot of the syntax to feel 'different for the sake of different.'

A few months ago, I began using Flutter for a sideproject (That I wanted to release). Although the developer experience is absolute fantastic (And definitely the future), the plugin ecosystem is extremely lacking. I wanted to use AWS, and there was 0 backing for it. Since I didn't want to interact with raw AWS APIs, I moved to React Native.

It looks like you could "wrap" native libraries using custom packages: https://flutter.io/developing-packages/#plugin . I'm curious which AWS APIs you'd want to connect your mobile app directly to. S3/ SQS?

I wanted to use Cognito & Lambda functions (Through the API Gateway). The AWS-Amplify library makes this super easy, but isn't available for Dart.

If there's a better way, please let me know! I loved Flutter, and I loved Dart.

The part I wish to have for things like this:

> We're also working to make it easier to add Flutter to your existing Android or iOS codebase.

Ideally, it must just refer a single lib + provide the path to the dart code/resources folders. Plus have a truly nice bridge/callbacks so I could have the heavy logic inside my native code.

ie, as easy as possible like with a webview.

I mean, if you're gunna use C++ libraries, is there a reason not to just make the whole app in C++ (like with Qt/QML)? Seems adding a new language/toolchain to the mix is a recipe for headaches. That's a genuine question :) I don't do any app development so maybe I'm missing something - is Qt not sufficient? It seems to run on everything as-is

I didn't say anything about C++ libraries, at least in case of my dream thing. The problem with Qt is that it draws its own widgets. It is close on some platforms like with Gtk+ theme, but most people report how it does not look native on their platform. Also on Android it has to use JNI and NDK so it's not native to Android as DEX/Java is. On Windows I believe that CLR or at least COM (you can do it even C, but that…

I see the limitation.. but I must be missing some subtle distinction b/c isn't Flutter doing essentially the same thing under the hood?

"The engine’s C/C++ code is compiled with Android’s NDK, and any Dart code is AOT-compiled into native code. The app runs using the native instruction set (no interpreter is involved)."

"The engine’s C/C++ code is compiled with LLVM, and any Dart code is AOT-compiled into native code. The app runs using the native instruction set (no interpreter is involved)."

why does the linked article calls ot out as "compressed" but not mention it for java bytecode?
