dart-lang/sdk

The Dart SDK, including the VM, dart2js, core libraries, and more.

I guess final className = '$A'; will do.

Simon Binder

@simolus3

This is actually specified (16.3): "A simple or qualified identifier denoting a class, a mixin or a type alias that is not qualified by a deferred prefix, is a potentially constant and constant expression. The constant expression always evaluates to a Type object." So final $class = A; resolves to a Type and final className = $class.toString() just calls Type.toString(), which is what the interpolation is doing as well.

Rob Halff

@rhalff

Ok, so it's like this:

class A {}

void main() {
  // Correct
  final $className = A;
  print($className.toString());

  // Will fail, A doesn't have a toString() method.
  print(A.toString());
}

ok, understood then.

note that in dart2js that name would probably be mangled though

Rob Halff

@rhalff

I'll be using it as a key so that's no problem.

  void registerView<T extends View>(dynamic viewFactory) {
    final className = '$T';

    if (views.containsKey(className)) {
      throw ArgumentError('View $className is already registered');
    }

    views[className] = viewFactory;
  }

@daadu_gitlab That looks to me like a bug. Tried it with your server and some others - you always seem to get the intermediate. My wild guess would be that something's picking the wrong cert (of the two provided) that are presumably returned by SSL_get0_peer_certificates see https://commondatastorage.googleapis.com/chromium-boringssl-docs/ssl.h.html#SSL_get0_peer_certificates. Even though boringssl returns the whole chain, the Dart closure just gets one - so whatever picks seems to pick the wrong one.

Jacob MacDonald

@jakemac53

@rhalff you can use the type itself as a key as well, fwiw

Rob Halff

@rhalff

@jakemac53 that's much better actually, thanks :)

any plans to add pub to this list? https://help.github.com/en/github/managing-packages-with-github-packages/about-github-packages#supported-clients-and-formats

Jacob MacDonald

@jakemac53

well, I just noticed that github actions natively support Dart so who knows maybe they will support pub too :D

also the github actions setup flow was really nice I was super impressed

Don

@donny-dont

doesnt pub still need an oauth flow

and tied to a google account

typedefs for non-functions in the works, :) dart-lang/sdk@d290f1c

RandalSchwartz @RandalSchwartz stumbles across dart2native and is happy

Randal L. Schwartz

@RandalSchwartz

dart can now give go a run for its money!

hey, does anyone here know if the dart sdk included with flutter is still a subset, or if it’s the full thing now?

Ping

@ping996

@RandalSchwartz flutter not use the dart:mirrors as I known

and flutter not support the native extension by instead of use the tonic third_party

Randal L. Schwartz

@RandalSchwartz

I know Flutter can't use mirrors but are they missing even from the included dart ask?

Ping

@ping996

I don't know, maybe the dart officer can clear your question.

Harsh Bhikadia

@daadu_gitlab

@richardheap I just realised that flutter bundles the truestedRootCAs with app itself and not trust the once in Android System. I guess that would be enough (as the server that I access uses LetsCrypt which is trusted) to prevent users from sniffing network call via CharlesProxy or something? what do you suggest?

Has anyone successfully used hot reloading in a web server app? I'm using shelf, and I've been trying to get this jaguar_hotreload package to work.

Jaguar-dart/jaguar_hotreload#6

It says it's reloading, but changes don't seem to take effect. Is this a common limitation of hot reloading? Do I need to manually tear down and rebuild my HttpServer instance with new instances of middlewares, router, controllers, and so on?

Rob Halff

@rhalff

@mindplay-dk there is also a Jaguar channel: https://gitter.im/jaguar_dart/jaguar It's a bit less active lately. I do like the whole Jaguar stack a lot btw, minor issues like that seem to happen as there are not so many maintainers.

Rob Halff

@rhalff

I've just tested the example and it gives the same issue.

Rasmus Schultz

@mindplay-dk

Thanks, Rob :-)

@rhalff wait, were you referring to the websocket issue, or did you get past that to actual change detection and hot reloading? I've got it reloading. Or it says it does. Just that making changes to source-files doesn't actually have any effect.

Rob Halff

@rhalff

@mindplay-dk I'm referring to the websocket issue actually.

Rasmus Schultz

@mindplay-dk

@rhalff yeah, I got past that, and will probably submit a PR for that... but there's a snippet you can copy here to get the correct URL: https://github.com/Jaguar-dart/jaguar_hotreload/issues/6#issuecomment-554336704

@rhalff without that, the example doesn't work at all.

Rob Halff

@rhalff

I also found the dependencies are a bit ancient, the package is now called vm_service instead of vm_service_lib

Rasmus Schultz

@mindplay-dk

@rhalff are you sure? the change change log says vm_service_lib was migrated into the standard SDK?

Rob Halff

@rhalff

oh ok..

now the example seems to work for me after your adjustment.

@mindplay-dk

Yeah, then it's probably what I suspected, it probably just doesn't work on Windows... 😐

I wanted to test if that was the case, but pub get doesn't seem to work under Ubuntu on WSL... man, I'm starting to hate Windows.

Rob Halff

@rhalff

I'm not really using windows, but cannot think of a reason why pub get wouldn't work for ubuntu.

Rasmus Schultz

@mindplay-dk

Ubuntu on WSL 1 has had plenty of IO and network issues, I don't know. I don't dare switch to the preview version of Windows required to run WSL 2, but supposedly that's much better.

Plenty of things motivating me daily as a developer to switch to native Linux anyhow, maybe it's time ;-)

Rob Halff

@rhalff

Or just dual boot, I have an second laptop running Windows 10, but never really touch it.

I don't get what people seek in windows, nor osx really. Only reason to own a mac is so you can use xcode.

Or work together with designers which use mac only stuff like Sketch :)

Rasmus Schultz

@mindplay-dk

Yeah, I want to dual boot for sure, I'm just a bit scared of bricking my Windows installation in the process... 😬

Rasmus Schultz

@mindplay-dk

@rhalff oh, you may be right about that package after all, it's flagged as "discontinued" https://pub.dev/packages/vm_service_lib

Rob Halff

@rhalff

@mindplay-dk you can just change it to vm_service in pubspec.yaml, the api hasn't changed it seems.

perhaps that does work on windows, not sure.
