如何启动angular.dart应用

Question

I am on angulardart 0.11.0 and this is my code for main.dart:

library my_app_main;

import 'package:angular/angular.dart';
import 'package:angular/application_factory.dart';

import 'package:my_app/src/something.dart';

class MyModule extends Module {
  MyModule() {
    bind(MyAppCtrl);
    bind(MyComp);
  }
}

main() {
  applicationFactory()
    .addModule(new MyModule())
    .run();
}

I get syntactic errors:

• angular.dart import is 'unused'
• 'Module' is an 'undefined class'

I have tried deleting and rebuilding the packages directory, pubspec file, etc. What is going on?

Answer 1

angular.dart import is 'unused' is just a warning, so you don't really need to worry about it.

You're seeing 'Module' is an 'undefined class' because you're not importing the di library. Add import 'package:di/di.dart'; to your imports and it should run.

Answer 2

Turns out the error was caused by the angular files becoming corrupted in the pub cache. As was pointed out here ( https://groups.google.com/forum/#!topic/angular-dart/WiZuIwxTDb4 ) - thanks Günter! - the solution is to repair the pub cache by doing 'pub cache repair' or at least 'pub cache add angular'
