Debugging MirrorsUsed - dart

I'm trying to figure out which libraries I need to pass to #MirrorsUsed to get my app compiled and working. Sometimes, it's easy to figure out which library may be missing since a descriptive error is thrown such as Uncaught Unsupported operation: Cannot find class for: NgAttr .
Other times, I get a more obscure message, such as NullError: Cannot call "$gt" on null with no clue as to which library I may be omitting. Is there a better approach to this, besides trial and error?
In case you're wondering, this is an angular app and this is how I currently have it configured:
#MirrorsUsed(targets: const[
'angular',
'angular.core',
'angular.core.dom',
'angular.filter',
'angular.perf',
'angular.directive',
'angular.routing',
'angular.core.parser.dynamic_parser',
'angular.core.parser.lexer',
'todo',
'perf_api',
'List',
'NodeTreeSanitizer',
'PlaybackHttpBackendConfig'
],
override: '*')
import 'dart:mirrors';

Use
pub build --mode=debug
this does tree shaking but retains (mostly) the original Dart names.
Then debugging the generated JavaScript usually lets deduce the source of the exception.
EDIT
IMHO these are not necessary anymore, because they were added to #MirrorsUsed in the Angular libs.
'angular',
'angular.core',
'angular.core.dom',
'angular.filter',
'angular.perf',
'angular.directive',
'angular.routing',
'angular.core.parser.dynamic_parser',
'angular.core.parser.lexer',

paper-datatable Port to Dart with custom_element_apigen: does not working

I am trying port to Dart this nice paper-datatable implementation using custom_element_apigen.
Some problems occurred and sought to find solutions according to my understanding (perhaps included more problems!).
However, still an error is thrown and not been able to move on. I need some help about how port to Dart!!! I will briefly describe the steps, errors and solutions that gave and a link to source code of the project test:
1) I following the steps, accord to https://github.com/dart-lang/custom-element-apigen. I had problems on Windows, but I got to resolve after (custom_element_apigen: gives an error importing paper-datatable to Dart)
2) apigen.yaml used with custom_element_apigen does not clear how to configuration.
I used the "trial-and-error" method until no more error occur. It was so:
files_to_generate:
- paper-datatable\paper-datatable.html
- paper-datatable\paper-datatable-column.html
- paper-datatable\paper-datatable-edit-dialog.html
- paper-datatable\paper-datatable-card.html
- paper-datatable\paper-datatable-styles.html
- paper-datatable\datatable-icons.html
files_to_load:
- package:polymer_elements/src/paper-material/paper-material.html
- package:polymer_elements/src/iron-ajax/iron-request.html
- package:polymer_elements/src/iron-ajax/iron-ajax.html
- package:polymer_elements/src/iron-form/iron-form.html
- package:polymer_elements/src/iron-meta/iron-meta.html
- package:polymer_elements/src/iron-icon/iron-icon.html
- package:polymer_elements/src/iron-iconset-svg/iron-iconset-svg.html
- package:polymer_elements/src/paper-ripple/paper-ripple.html
- package:polymer_elements/src/paper-checkbox/paper-checkbox.html
- package:polymer_elements/src/neon-animation/animations/opaque-animation.html
- package:polymer_elements/src/neon-animation/animations/fade-in-animation.html
- package:polymer_elements/src/neon-animation/animations/fade-out-animation.html
- package:polymer_elements/src/paper-tooltip/paper-tooltip.html
- package:polymer_elements/src/iron-resizable-behavior/iron-resizable-behavior.html
- package:polymer_interop/src/js/debug/src/lib/template/templatizer.html
Some paths imports were wrongs on paper-datatable*.(html and dart) files. p.e. : import 'packages\polymer_interop\src\js\debug\src\lib\template\templatizer.dart'; I changed to import 'package:polymer_interop/src/behaviors/templatize.dart';
on paper_datatable_column.dart.
I changed reserved Dart word default to defaultx on get defaultx => jsElement[r'default']; and set defaultx(value) { jsElement[r'default'] = (value is Map || (value is Iterable && value is! JsArray)) ? new JsObject.jsify(value) : value;} instructions on paper_datatable_column.dart and paper_datatable_card.dart;
After the following erros were occuring in several polymer componentes. P.e.: Failed to execute 'registerElement' on 'Document': Registration failed for type 'iron-meta'. A type with that name is already registered.
I changed all paths into paper-datatable*.* files to get official package (pub.dartlang) of the polymer and polymer elements. P.e.: <link rel="import" href="paper_icon_button_nodart.html"> to <link rel="import" href="../../packages/polymer_elements/paper_icon_button_nodart.html">. The register problem does not occur more!
But now, the following problem is occuring and I don't know how to resolve it: On debug console appear the following message: Uncaught SyntaxError: Unexpected token =>. The web app works on browser, but the paper-datatable does not appear.
My complete test project (webstorm) is on https://github.com/supermuka/paper_datatable_port_dart_demo
Is there some wrong in how I used Dart custom_element_apigen (and apigen.yaml)? Did I some things wrong on paths changed? I also need to change some other source?
Thanks!
Most likely you just created a syntax error when editing the files. That being said there are options built in to do most of the things you manually did, and that also makes it easier to update in the future.
omit_imports: This is used on individual items in the files_to_generate section. It can be used to get rid of the templatizer import entirely, resolving issue #3. See example here.
name_substitutions: This is used on individual items in the files_to_generate section, and allows you to rename fields. You can use this to resolve issue #4, example here.
stubs_to_generate: This option allows you to generate stubs which actually import elements from a different package, this should resolve issue #5 you listed above. See example usage here.
Hopefully that helps, and applying those options will just resolve your issues.

AngularJS with .NET MVC Bundling Minification Error

I have been developing a large AngularJS application inside of a .NET MVC Website. I've gone way to long without testing if it will sucesfully minifiy using the Bundle Optimiazation Features?
BundleTable.EnableOptimizations = True
And of Course, it fails. I've been playing with the Order I bundle my scripts, and ensuring I am using String Literals for my Controller Names (I wasn't, and that is a lot of re-factoring that I will have to do).
But I can not get my Core Scripts to Minifiy without the angular "Unknown Provider" error.
Here is the exact Error:
Uncaught Error: [$injector:modulerr] [http://errors.angularjs.org/1.3.14/$injector/modulerr?p0=ppAccount&p1=Error…redScripts%3Fv%3DknV3wkCOg32ajaw4GwiRSrTXdo8Ue7MRIn65CPYa1b81%3A1%3A379851)]1
Here is my bundle config that is failing:
bundles.Add(new ScriptBundle("~/bundles/PilotPartnerRequiredScripts")
.Include(
"~/UI/js/jquery/jquery-2.1.3.js",
"~/UI/js/plugins/jquery-ui/jquery-ui.js",
"~/UI/js/bootstrap/bootstrap.js",
"~/UI/js/plugins/pace/pace.min.js",

"~/Scripts/uiSortable/sortable.js",
"~/Scripts/kendo/2014.3.1119/kendo.all.min.js",
"~/Scripts/xeditable/xeditable.js"
For the life of me, I can't figure out which dependency isn't being resolved. I feel that if I can narrow it down to a specific dependency I know I can solve the issue.
Is there any way to track down the specific Module that is causing the issue?
Any suggestions on how to make this work?
Thank you for your help.
You should always follow strict di while injecting dependency (Array notation)
Angualar Doc has mentioned that, Do follow strict DI while doing minification, otherwise it could break you app
Eg.(Code)
angular.module('myModule', [])
.factory('serviceId', ['depService', function(depService) {
// ...
}])
.directive('directiveName', ['depService', function(depService) {
// ...
}])
.filter('filterName', ['depService', function(depService) {
// ...
}]);
In above snippet I followed inline array notation of DI, it has been applied on various angular component just to demonstrate it. You should make sure that you follow it wherever you're injecting dependency.

Which way to go with these bugs

Compiling Dart app to js these two errors arise:
Nº1:
InvalidStateError: Failed to call 'register' on 'Document' for type 'polymer-element': a type with that name is already registered.
Nº2:
Breaking on exception: TypeError: Object #<qE> has no method 'vL'
The object qE is created by dart2js.
How to find the solution?
There are appropriate tools to find the solution?
Thanks for advance !
I heard N1 occurs when Angular and Polymer is used in the same app. This is a known bug.
related open issues:
- duplicate polymer-element registration should not break the app
- Get error "Uncaught InvalidStateError: Failed to call 'register' on 'Document' for type 'polymer-element'
For the N2 use pub build --mode=debug so you get unmangled names and then use one of the available strategies to fix the problem (use of MirrorsUsed, #observable, #reflectable)

Compiled AngularDart fails with error in dynamic_injector

I have been trying to make AngularDart work but I always get exceptions for undefined objects.
#MirrorsUsed(
targets: const [
'angular.core',
'angular.core.dom',
'angular.core.parser',
'angular.routing',
'angular.core.zone',
'di.di',
'di.dynamic_injector',
NodeTreeSanitizer,
DynamicParser,
DynamicParserBackend,
Injector
],
metaTargets: const [
NgInjectableService,
NgComponent,
NgDirective,
NgController,
NgFilter,
NgAttr,
NgOneWay,
NgOneWayOneTime,
NgTwoWay,
NgCallback,
NgZone
],
override: '*'
)
import 'dart:mirrors';
And compiled javascript showing error:
Uncaught TypeError: Cannot call method 'get$parameters' of undefined dynamic_injector.dart:42
DynamicInjector.newInstanceOf$4 dynamic_injector.dart:42
When I'm removing MirrorsUsed2 there is no errors, but compiled file is large.
Adding these helped for me
'angular.filter',
'angular.perf',
'perf_api',
and instead of angular.core.parser
'angular.core.parser.dynamic_parser'
'angular.core.parser.lexer'
I also added all my own libraries.
See also https://code.google.com/p/dart/issues/detail?id=14686
Recently, I found Dart-AngularJS when compiled not to run, even the simplest example. I reinstalled my dart sdk to the latest stable version and the errors disappeared. Could you see if this works? Please see related issue on github project.

Get warnings when programmatically parsing Dart file with analyzer_experimental

I am using analyzer_experimental to parse a Dart file into a CompilationUnit:
import 'package:analyzer_experimental/analyzer.dart';
var unit;
try {
unit = parseDartFile(path);
} on AnalyzerErrorGroup catch(e){
print(e);
}
The above code will catch any parsing errors encountered.
I am also interested in seeing any warnings associated with the file (e.g. 'Undefined name "foo"'). I know that the experimental_analyzer library has the capability to generate these warnings when running from the command line but it does not seem to be possible to get the warnings programmatically, without directly referencing classes in the src folder (which seems like a bad idea).
Is there any way to achieve this?
It's likely this package was very incomplete at the time.
There's now an analyzer package on pub and also a (work-in-progress) STDIN/STDOUT Analyzer Service aimed to help making tooling support easier for IDE extension authors.
