    <p>I've ported a handy JS library to Dart: <a href="https://github.com/martyglaubitz/dartscale" rel="nofollow">dartscale</a>. The crucial part of it's functionality can be broken down to:</p> <pre class="lang-dart prettyprint-override"><code>final Map&lt;Symbol, ClassMirror&gt; _registeredModules = new Map&lt;Symbol, ClassMirror&gt;(); register(module, [String moduleName]) { final uniqueModuleName = moduleName != null ? moduleName : module.runtimeType.toString(); final Symbol uniqueModuleIdentifier = new Symbol(uniqueModuleName); if (_registeredModules.containsKey(uniqueModuleName)) { throw new StateError("Module ${moduleName} already registered!"); } final ClassMirror mirror = reflect(module).type; _registeredModules[uniqueModuleIdentifier] = mirror; } start(Symbol moduleName, String id, options) { if (!_registeredModules.containsKey(moduleName)) { throw new StateError("Module ${moduleName} not registered!"); } final ClassMirror mirror = _registeredModules[moduleName]; final Symbol moduleId = id != null ? new Symbol(id) : moduleName; final Sandbox sandbox = new Sandbox(this.mediator); if (_runningModules.containsKey(moduleId)) { throw new StateError("Module with id #${moduleId} already running!"); } final InstanceMirror moduleInstance = mirror.newInstance(new Symbol(''), [sandbox], null); moduleInstance.invoke(new Symbol("start"), [options]); _runningModules[moduleId] = moduleInstance; } </code></pre> <p>i also provide an example</p> <pre class="lang-dart prettyprint-override"><code>part of example; class ToDos { Sandbox _sandbox; DivElement _contentEl; int _nextToDoId = 0; UListElement _todoList; ToDos ([Sandbox this._sandbox]); start([Map options]) { this._initLocalStorage(); var html = ['&lt;div id="module-todos"&gt;', '&lt;form&gt;', '&lt;input type="text" class="input-medium"&gt;', '&lt;button type="submit" class="btn"&gt;Add&lt;/button&gt;', '&lt;/form&gt;', '&lt;ul&gt;', '&lt;/ul&gt;', '&lt;/div&gt;'].join(''); this._contentEl = new Element.html(html); this._todoList = this._contentEl.query('ul'); options['containerEl'].append(this._contentEl); window.localStorage.keys.forEach((key) =&gt; this._renderToDo(key)); this._setupEvents(); this._sandbox.channel('navigationbar').topic('filter').listen((filterContent) { this._filter(filterContent); }); this._sandbox.channel('navigationbar').topic('clearfilter').listen((filterContent) { this._todoList.queryAll('li span').forEach((element) =&gt; element.parent.classes.remove('hide')); }); } stop() { this._contentEl.remove(); } _initLocalStorage() { if (window.localStorage.keys.length == 0) { var map = { "1": { "subject": "Groceries: Banas and Apples", "isDone": false }, "2": { "subject": "Taxes: take care of them", "isDone": false }, "3": { "subject": "Bring out trash", "isDone": false } }; for (var key in map.keys) { window.localStorage[key] = stringify(map[key]); this._nextToDoId++; } } else { for (var key in window.localStorage.keys) { var intKey = int.parse(key); if (intKey &gt; this._nextToDoId) { this._nextToDoId = intKey; } this._nextToDoId++; } } } _setupEvents() { var input = this._contentEl.query('input'); input.onKeyDown.listen((event) { if (event.keyCode == KeyCode.ENTER) { event.preventDefault(); this._addToDo(input.value); input.value = ''; } }); this._contentEl.query('button[type="Submit"]').onClick.listen((event) { event.preventDefault(); if (input.value.length &gt; 0) { this._addToDo(input.value); input.value = ''; } }); this._todoList.onClick.listen((MouseEvent event) { var el = event.target; if (el.classes.contains('icon-remove')) { this._deleteToDo(el.parent); } else if (el.classes.contains('icon-ok')) { this._toggleToDoDone(el.parent); } }); } _renderToDo(id) { var todoObject = parse(window.localStorage[id.toString()]); var html = ['&lt;li class="record-todo ', todoObject["isDone"]?"done":"",'" data-id="', id,'"&gt;', '&lt;span&gt;', todoObject["subject"], '&lt;/span&gt;', '&lt;i class="icon icon-ok"&gt;&lt;/i&gt;', '&lt;i class="icon icon-remove"&gt;&lt;/i&gt;', '&lt;/li&gt;'].join(''); this._todoList.append(new Element.html(html)); } _addToDo(text) { var todoJson = stringify({ "subject": text, "isDone": false }); window.localStorage[this._nextToDoId.toString()] = todoJson; this._renderToDo(this._nextToDoId); this._nextToDoId++; } _deleteToDo(todoLIElement) { window.localStorage.remove(todoLIElement.dataset["id"]); todoLIElement.remove(); } _toggleToDoDone(todoLIElement) { var done = !todoLIElement.classes.contains('done'); var id = todoLIElement.dataset["id"]; var todoObject = parse(window.localStorage[id]); todoObject["isDone"] = done; window.localStorage[id] = stringify(todoObject); if (done) { todoLIElement.classes.add('done'); } else { todoLIElement.classes.remove('done'); } } _filter(content) { this._todoList.queryAll('li span').forEach((element) { if (element.innerHtml.contains(content)) { element.parent.classes.remove('hide'); } else { element.parent.classes.add('hide'); } }); } } </code></pre> <p>in my App.dart</p> <pre class="lang-dart prettyprint-override"><code>library example; import 'dart:html'; import 'dart:json'; import '../lib/dartscale.dart'; part 'dart/ToDos.dart'; main () { var core = new Core(); core.register(new ToDos()); core.start("ToDos", "ToDos", { "containerEl": query('body &gt; .container') }); } </code></pre> <p>bug in dart2js ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
