Migrating from AngularDart 0.14.0 to 1.0.0

I have a fairly large web application that is build using the @Controller annotation in AngularDart 0.14.0. The @Controller annotation has been removed so I need to migrate to something else. So my questions are what do I migrate to, and how do I do it. I have looked at the documentation for the @Component annotation, but I don’t see a way to migrate to it without requiring a large amount of rework. I hope that I am missing something. I have looked at other similar questions, but none of them have lead me to a solution.

Here is a cut down example of how I am using @Controller.

pubspec.yaml

name: Admin
description: Server Admin Page
dependencies:
  angular: 0.14.0
transformers:
- angular:
    html_files: web/index.html

index.html

<!DOCTYPE html>
<html ng-app>
<head>
  <meta http-equiv="X-UA-Compatible" content="IE=edge" >
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>Server Configuration</title>
</head>
<body>
  <div admin id="container">
    <div id="header">
      <div id="app-header"><span id="app-name">Server Configuration</span></div>
      <div class="tab-panel ng-cloak" >
        <div class="{{ctrl.selectedTab != null && tab.name == ctrl.selectedTab.name ? 'tab-selected' : 'tab'}}" ng-repeat="tab in ctrl.tabs">
          <div class='tab-inner' ng-click='ctrl.selectTab(tab)'>{{tab.name}}</div>
        </div>
      </div>
    </div>
    <div id="body">
    <div class="ng-cloak" ng-if="ctrl.selectedTab != null" >
      <div>{{ctrl.selectedTab.name}} Content</div>
    </div>
    </div>
</div>
<script type="application/dart" src="index.dart"></script>
<script type="text/javascript" src="packages/browser/dart.js"></script>
</body>
</html>

index.dart

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

@Controller(
    selector: '[admin]',
    publishAs: 'ctrl')
class AdminPage{
  AbstractTab selectedTab;
  List<AbstractTab> tabs = new List<AbstractTab>();

  AdminPage()
  {   
    tabs.add(new AbstractTab("tab1","tab"));
    tabs.add(new AbstractTab("tab2","tab"));

    this.selectTab(tabs.first);
  }

  void selectTab(AbstractTab tab)
  {
    this.selectedTab = tab;
    this.selectedTab.load();
  } 
}

class AbstractTab{
  String name;
  String type;

  AbstractTab(this.name,this.type);

  load()
  {
    print("loading $name");
  }
}

class MyAppModule extends Module {
  MyAppModule() {
    bind(AdminPage);
  }
}

void main() {
  applicationFactory()
      .addModule(new MyAppModule())
      .run();
}

Update:

My updated index.dart file now looks like this, and everything is working in AngularDart 1.0.0. Thank you for the assistance.

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

class AdminPage{
  AbstractTab selectedTab;
  List<AbstractTab> tabs = new List<AbstractTab>();

  AdminPage()
  {   
    tabs.add(new AbstractTab("tab1","tab"));
    tabs.add(new AbstractTab("tab2","tab"));

    this.selectTab(tabs.first);
  }

  void selectTab(AbstractTab tab)
  {
    this.selectedTab = tab;
    this.selectedTab.load();
  } 
}

class AbstractTab{
  String name;
  String type;

  AbstractTab(this.name,this.type);

  load()
  {
    print("loading $name");
  }
}

@Injectable() // don't forget that
class GlobalController {
  AdminPage ctrl;

  GlobalController() {
    ctrl = new AdminPage();
  }
}

void main() {
  applicationFactory().rootContextType(GlobalController).run();
}

I have been in the same situation like you, and I have to admit that documentation about "how to do it properly in angular V1" is lacking.

So actually, the best way I found is to use a global controller

main.dart

@Injectable() // don't forget that
class GlobalController {
  final Logger log = new Logger("GlobalController");
  AdminPage ctrl;
  OtherCtrl otherCtrl

  GlobalController() {
    ctrl = new AdminPage();
    otherCtrl = new OtherCtrl();
  }
}

void main() {
  applicationFactory().rootContextType(GlobalController).run();
}

index.html

<!DOCTYPE html>
<html ng-app>
<head>
  <meta http-equiv="X-UA-Compatible" content="IE=edge" >
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>Server Configuration</title>
</head>
<body>
  <div admin id="container">
    <div id="header">
      <div id="app-header"><span id="app-name">Server Configuration</span></div>
      <div class="tab-panel ng-cloak" >
        <div class="{{ctrl.selectedTab != null && tab.name == ctrl.selectedTab.name ? 'tab-selected' : 'tab'}}" ng-repeat="tab in ctrl.tabs">
          <div class='tab-inner' ng-click='ctrl.selectTab(tab)'>{{tab.name}}</div>
        </div>
      </div>
    </div>
    <div id="body">
    <div class="ng-cloak" ng-if="ctrl.selectedTab != null" >
      <div>{{ctrl.selectedTab.name}} Content</div>
    </div>
    </div>
</div>
<script type="application/dart" src="index.dart"></script>
<script type="text/javascript" src="packages/browser/dart.js"></script>
</body>
</html>

It works perfectly for me.

Note: Notice that all method and field of your GlobalController will be directly accessible. in this example if you want to access to otherCtrl, just use otherCtrl in your HTML file.

Note2: You don't have to put anything in your HTML balise to make this work.

Information: I know in migration you can't allow big refactoring, but for you future development, Angular advice to split your code into more components.
