I used to be able to modify the snippet for a Dart class editing .vscode/extensions/dart-code.dart-code-X.YY.Z/snippets/dart.json, but since some recent versions (VSCode? Flutter? Dart?) my customized snippet is not being taken into account, the default snippet for a Dart class only.
How/Where to customize the snippet for a Dart class?

I am trying to implement an OpenTok application using codename one. I already started with android and had pretty much everything working. I use a native interface to import the OpenTok library.
Now I am trying to implement the ios side. I have a class acting like the view controller :
#interface be_lsit_opentok_iosTestHelper <OTSessionDelegate, OTPublisherDelegate> : NSObject
This class implements all the needed methods for the session connection : https://tokbox.com/developer/tutorials/ios/basic-video-chat/ (step 4).
My class implementing the native interface handles the initialization of the session with the api_key... and then calls the session's "connectWithToken".
Once this is done I can notice using the OpenTok Playground that the connection works but I do also notice that opentok does not send a message to call the method "sessionDidConnect" which is a problem.
I do not understand why the call is not done and what sould I do?
I also tryed to call the method myself using a thread call the method only when the connection to the session is made and that its status is "OTSessionConnectionStatusConnected" and this worked.
I'm guessing here since I didn't do this. You implemented the viewDidLoad in your own code instead of the Codename One view did load.
You can inject code into the Codename One viewDidLoad method using the build hint ios.viewDidLoad. So a build hint like:
ios.viewDidLoad=[self connectToAnOpenTokSession];
Should work but you would also need to add an import for the API into our code. Unfortunately I couldn't find a suitable build hint to define that so I added one ios.viewDidLoadInclude which I will add tomorrow to the build will allow you to define an import or include statement required by the statement above.
I've added module highcharts in Flow project as it is written over here. Basically the problem is that whenever I use library Highcharts , I have to put into the code import Highcharts from "highcharts"; The results outcome with no errors in FlowJs interface, but with error in browser Unexpected token import( so it doesn't compile js file properly) . Does anyone know the answer for that? I would be appreciated!
Flow in general uses nonstandard syntax for type annotations, etc. In your case, the import is standard ES6 syntax, but it's not yet supported in whatever browser you are using.
Either way, the solution is to use Babel to transpile your code. You can configure it to target older versions of JavaScript and to strip Flow types. There's a bit more info about using it with Flow on the Running Flow code page.
I'm developing a DSL using xText (version 2.10.0) and i would like to add also a code generator.
When running the plug-ins, as I understood, the code generator should be invoked automatically upon a change in a file.
This is not happening.
Using a debugger I've noticed that the doGenerate function is not invoked.
What can I do so the doGenerate function will be invoked automatically?
Thanks.
Your file needs the right file extension (case sensitive) the project needs xtext nature and build automatically needs to be enabled. Then the generator will be called upon save of error free models
I try to use JavaScript library visjs.org in Dart. I prepared ‘adapter’ code according examples on Dart site pub.dartlang.org/packages/js and github.com/google/chartjs.dart/blob/master/lib/chartjs.dart.
Also according basic use case example from http://visjs.org I prepare client dart code.
While code compiles without any errors and warnings nothing happens in browser, expected to see graph-tree.
What I did wrong or miss to do?

The attribute #anonymous is meant to be used when the object you're describing doesn't actually exist in the JS library you're binding, and is only used as a plain old data object. By adding it to all of your objects, my guess is that dart is never attempting to create anything from the visjs library.
Try removing the #anonymous from your Network class and see if that has an effect. You will likely also need to make these abstract classes as well.
I am working with the Grails Authentication plugin and trying to add a domain class from the plugin into my GORM. I am able to use plugin objects in my application when importing them with, "import com.grailsrocks.authentication.AuthenticationUser", but getting "unable to resolve class" exception when trying to access my application objects from the plugin (I am trying to use the domain class "User" and my import command is "import blap.User" - package name is blap). Both import commands work from the shell, and the import statement is not triggering an error in STS.
I am new to grails, so I'm probably doing something very wrong. But, at this point I am running out of ideas, so any help would be greatly appreciated. Thanks!

While I haven't used the Grails Authentication plugin before, I don't think you should be modifying the plugin classes. In general, you should extend the plugin class you want to modify in your application and use your application class instead.
Actually, from reading the docs, it looks like you should use the event handling to modify the plugin behavior.
From the plugin docs:
The default AuthenticationUser domain class is minimal. If you want to change constraints or add fields (you may consider using a separate class instead for extra user data) you just redefine the onNewUserObject event and return your own instance of a domain class or similar wrapper around another authentication database such as LDAP
