Dart Polymer white screen of death? - dart

I have a project that works fine when I view as Javascript but when I boot it in Dartium nothing is shown. There is no errors either. I am not sure what I have done. Even other projects that haven't had their code touched for weeks no longer can be view in Dartium so I assume it's a dodgy package but pubspec only uses browser, polymer, tweenengine.
Thoughts?

I also had that problem yesterday. Deleting Dart Editor + Dartium and installing it again, fixed it for me. A Friend also had that problem, reinstalling also fixed it for him.

Spyder 5.3.3. switch to editor shortcut, copy and paste a file in the project file tree [duplicate]

I'm on Windows 10 and recently updated to Spyder 5.3.3 standalone version and the keyboard shortcut to switch to the editor pane (default Ctrl+E) will not work no matter what I try, it simply has no effect.
I've tried reinstalling Spyder, resetting everything back to defaults multiple times, changing to different keyboard shortcuts than Ctrl+E, trying to switch to the editor pane while having various other panes selected (different contexts), but nothing helps. I can switch to all other panes (like the console with Ctrl+I, etc) just fine and so far all of the other key shortcuts I'm used to work but this one is the most impactful and I can't get it to work. I opened my previous version of Spyder 4.X and the Ctrl+E works fine from any context as expected.
Any ideas on what the issue could be?
Same issue here, and I think the issue started with the upgrade from 5.3.2 to 5.3.3 only. Before that it still worked.
The issue appears to be version-specific.
Have upgraded from 5.3.3 to 5.4.0, and the shortcut is working again.

Images not showing in react native application in release mode

React native application is working absolutely fine in debug mode but running in release mode image are not visible. I am using react-native#0.62.2.
I tried some solution from react-native iOS app not showing static assets (images) after deploying
but still not working.
I get this in xcode console
EDIT:
Found out that the error is because of a package "react-native-webview-quilljs". Installing it doesn't create problem but when importing it. After import app will run but editor will not render as well as all the images are not rendering.
This thread solved the issue for me: https://github.com/facebook/react-native/issues/29279#issuecomment-658244428
You can find that file in your node_modules folder. It seems like there was an issue with the Image module and they didn't fix it until the most recent version of React Native at the time of posting. Hope it works for you. Maybe someone who understands it more can elaborate on why exactly it solves the issue.

Angular dart on WebStorm. Debug is no more working

It is a week now that I have problems debugging angular dart applications in WebStorm. If I use debug on a console (server) application everything works fine.
I tried to roll back to angular 4.0.0 (on dart 1.24.3), but this didn't help.
I really don't know what kind of info could be useful.
Please, let me know if there is some configuration file that I can print or that could be important in order to fix the problem. I tested a lot of configurations, but, at present, I'm not able to work properly. After filling up my code with print statements, there are some cases where also this practice is not enough.
Edit1:
I have tried to create a sample project. With no DDc and target chrome, the debugger stops but not on all breakpoints. With no DDc and target Dartium, it does not stop.
Edit 2:
I was running my application with target dartium, because with target chrome I had an annoying error that I was not able to catch. Now I got it, and running the project with target chrome, revives the debugger. This is a good new. Just a question, is a problem of release 1.24.3 (Dartium has not been released for this release) or something else? Anyway, if this is a known problem, it wouldn't be better to disable the target dartium on WebStorm when the release is 1.24.3?
Edit 3:
Now the debugger is working, but only on the project you are developing. The imported packages are not stopping on breakpoints. As my project is divided in a lot of packages, I cannot debug approximately 80% of my code.
Am I doing something wrong?
What you are hitting here isn't functionality directly in an Angular Dart or Dart issue, but in the JS Debugger in WebStorm.
Open an issue on YouTrack here: https://youtrack.jetbrains.com/issues
Include not only the version of Angular and the Dart SDK, but also the version of WebStorm, and an example of where breakpoints are not working.
Finally, there is some information in this issue that might help: https://youtrack.jetbrains.com/issue/WEB-30593

Multi node tree picker Umbraco 7.2.1 unable to sort

Has anyone ran into this problem, on Umbraco 7.2.1, I'm unable to sort any nodes once seleted
There is no JavaScript errors and have looked at Umbraco.controller.js and added breakpoints in Chrome. The js file get hit when adding or removing items, but when trying to sort nothing.
In Umbraco 7.3.4, this feature works OK.
Is this a bug in 7.2.1
I believe this is indeed a bug in 7.2.X. I've experienced issues with sorting as a whole on the 7.2 platform.
In the link below, you'll see there has been issues with sorting in 7.1 as well.

Dart code not working after compiled to JS

So.. there's something weird happening to me.
My code in Dartium was working perfectly until I compiled it o JS. Now only the JS version of it works.. If I compile to JS then I run the program it works. But the Dart Code by itself no long works anymore :(
Does anyone had encountered a similar problem? IS it normal?
If necessary I can paste the entire program here.. but the problem is that Dart is not throwing me any errors and my compiled code works, so I don't know where to look at :(
Thanks!
There were some (maybe) similar problems mentioned lately which were solved by updating to a new Dart version.
If it's not that it's even weirder.
