Experiments with sorting algorithms in Dart, from Wikipedia articles.

	void bubble(List list) {
	var n = list.length;

	while (n != 0) {

Example of lazy loading with Dart.

	@lazy
	import 'big_lib.dart' as big show soManyFunctions;

	const lazy = const DeferredLibrary('big', uri: 'big.js');

	void main() {

sethladd / secret_santas.dart

Created December 9, 2013 05:46

My humble entry for Dart Dare - Secret Santa. I'm sure there are smaller or faster ways to do this. However, I wanted to try to solve the problem with sorting and processing lists. The entire solution hinges on sorting the santas by last name and by family size. Features of Dart that I used: * Classes * String interpolation * Type annotations * …

	class Person {
	String firstName, lastName;
	Person(List<String> raw) : firstName = raw[0], lastName = raw[1];
	String toString() => '$firstName $lastName';
	}

	/**
	* Expects one person per line, each line containing a first and last name
	* separated by a single space.
	*/

Testing an encapsulated gplus in polymer, both JS and Dart. Lots of caveats here. Make sure the plusone.js file is loaded before polymer (or, figure out all the async calls to wait until plusone is done loading). Note: normal gplus doesn't work because it scans the page looking for elements to upgrade. Of course, polymer puts everything into the…

	import "package:google_oauth2_client/google_oauth2_browser.dart";
	import "package:js/js.dart" as js;
	import 'dart:html';
	import 'package:logging/logging.dart';

	typedef OnSignInCallback(SimpleOAuth2 authenticationContext, [Map authResult]);
	typedef OnSignOutCallback();

	final Logger log = new Logger('google-sign-in-element');

Lifecycle callback when an element leaves a view. The JavaScript version works (I see I leave you now in the console) but the Dart version doesn't display the 'I leave you now'. Note: the x-b and its children do disappear from the page. This code is about removed() in x-c not firing.

Potential bug in test_dart.html? You should see: A: [From A] B: [From A] C: [From A] Instead I see: A: [] B: [] C: [] To fix, remove the initialization of the published attributes. IOW don't set `@published String type = ''` to a blank string FWIW, looks like test_js.html works.
