What is package naming convention used in Dart?

和自甴很熟 提交于 2020-02-23 08:51:28
问题 Is there a naming convention for Dart packages? Is there maybe a document that describes patterns? I have trouble figuring out naming convention for package names that consist of multiple words. For example, should I use placeView , PlaceView , place_view , or something else? 回答1: This is documented on the name section of Pubspec Format documentation . It should be all lowercase, with underscores to separate words, just_like_this . Stick with basic Latin letters and Arabic digits: [a-z0-9_]

Symbol with private identifier argument

余生长醉 提交于 2020-01-23 02:51:32
问题 I want to create a symbol equal to that of a private MethodMirror's simplename. However, Symbol's documentation states the argument of new Symbol must be a valid public identifier. If I try and create a const Symbol('_privateIdentifier') dart editor informs me that evaluation of this constant expression will throw an exception - though the program runs fine, and I am able to use it without any issues. void main(){ //error flagged in dart editor, though runs fine. const s = const Symbol('_s');

What are the Dart update channels?

问题 On the Dart Editor page we can choose between 2 channels : dev and stable . What are the differences between them ? 回答1: This post of Rico Wind explains that very well : dev channel will be something like the integration builds we offered before, i.e., weekly or biweekly releases. stable channel will only get critical bug fixes and otherwise be updated to a new minor version with something like 6 week intervals (this is not a guarantee, some releases may come faster some may come slower). Dev

dart: debugging client/server communication for dart client and existing rest api?

你离开我真会死。 提交于 2020-01-11 03:56:27
问题 I have a rest api (developed in django/python) which i run locally and want to develop a simple client application in dart. This client uses XMLHttpRequest to communicate to a local django development server. The problem is the default run configuration in the Dart Editor launches it's own web server and than either dartium or the system browser with dart2js. Which will both obviously violate the cross origin policy when i try to access my rest api. I'm wondering what the best setup would be

Print statement versus stdout performance and Dart-Editor versus command-line performance

一笑奈何 提交于 2020-01-06 02:10:49
问题 This is probably not of major importance, however I have noticed during testing that the performance of the print statement and also stdout is much faster in the Dart-Editor than from the command-line. From the command-line the performance of print takes around 36% longer than using stdout from the command-line. However, running the program from within the editor, using stdout takes around 900% longer than using the print statement in the editor, but both are considerably faster than from the

Is there an “Immediate Window” in the Dart Editor / Debugger?

孤人 提交于 2020-01-05 09:07:26
问题 Is there any way to try Dart expressions and execute commands while in a debug breakpoint? Like in Chrome Developer Bar, Firebug or Visual Studio Immediate Window. 回答1: Unfortunately not yet. Star http://dartbug.com/3293 to track its progress. A similar feature, a REPL (read-eval-print-loop) is tracked with http://dartbug.com/4409. 来源: https://stackoverflow.com/questions/15702450/is-there-an-immediate-window-in-the-dart-editor-debugger

How to make Dart Editor find referenced packages

…衆ロ難τιáo~ 提交于 2019-12-25 02:56:14
问题 In the Dart Editor (x64), I create a new project from the "Polymer Web Application" template. Immediately after creation, Dart Editor runs pub get command, executes building workspace. Then for every import directive, like import 'package:polymer/polymer.dart'; I got the following error: Target of URI does not exist: 'package:polymer/polymer.dart' How can I make Dart Editor understand references for standard libraries? 回答1: I assume your pub-cache is corrupted which can usually be fixed by

How to debug client side dart code in Dart editor without CORS

送分小仙女□ 提交于 2019-12-24 10:44:28
问题 I have a server / client project, both written in dart. Now my server starts on port 1337 and when I run my client with the Run in dartium , my static files are served on port 3030 which allows me to debug my client code in the Dart editor. The problem is that this causes CORS when using AJAX calls. I have properly setup my server to accept other origins (with Access-Control-Allow-Origin ) but, for example, cookies aren't sent along. Now I'm wondering: is there a way to serve my files with my
