I tried to run my flutter web project on browser using webdev serve command but it showed me the following error:
~/Desktop/web_project/hello_world$ webdev serve
webdev could not run for this project.
Could not find a file named "pubspec.yaml" in "/home/mehdi1514/.pub-cache/hosted/pub.dartlang.org/protobuf-0.13.11".

I am learning Dart (2.9.3). I use pub global activate webdev command.
I think it will work like npm in Node.js and create pubspec.yaml automatically, but it didn't.
Do I need to add more switches (like --save) to pub global?
Thank you.
The pub global activate webdev command activates webdev package to use on your computer. This package is
A command-line tool for developing and deploying web applications with Dart.
As author wrote in usage section
webdev provides two commands: serve and build.
But neither of both creates pubspec.yaml file.
If you want to generate a project, you can use stagehand. But there is no option to generate customized pubspec.yaml file. Dart must know which packages to use in a particular project, and only this file can provide those informations.
While running the Get Started guide for Dart and using WebStorm as per the docs, Dartium window shows "502 Bad Gateway" when trying to run index.html for the first time.
When inspecting the IDE, the Pub Serve console shows an error while trying to run % .../pub serve web --port=<port>:
No pubspec.lock file found, please run "pub get" first
I went into my get_started project folder on the terminal and ran the same pub serve command and got the same error.
I am running WebStorm 2016.3.2 and Dart sdk 1.21.0 on Linux x64.
What is the proper procedure to follow here?
WebStorm IDE has been known to have this bug where it fails to run pub get on a project which will cause failures when trying to run the project.
To verify if this is occurring, go into the IDE and check for a Pub Serve warnings message at the bottom of the window. If you see the errors outlined in the OP, then this solution should work.
The problem without running pub get is that the project dependencies have not been resolved and thus the server cannot start.
In the IDE, check the project root for a file pubspec.yaml. Right click the file and select Pub: Get Dependencies. Check the Messages window to follow for the progress. If it finishes ok, the problem should be corrected.
Alternatively, you could run pub get manually from command line as you would do without an IDE.

I just download andgularjs dart tutorial from angulardart.org . It provides me some tutorials, but I couldn't able to run those tutorials.
I am using webStorm IDE to run those application. when I am trying to run the application, I am getting following error.
enter image description here
I couldn't find package folder with in web root folder in that application.
You probably need to run pub upgrade. WebStorm provides this action in the context menu of the pubspec.yaml file, also if you open the pubspec.yaml file in the WebStorm editor links for pub actions are shown in the top-left corner of the editor. Alternatively you can run pub run from the command line of your project directory if the path is configured properly on your system so the command is found.
I am trying to create an ionic app on Mac.
I followed the instructions on ionic's website to create a basic app and was able to run it in the browser but when I run "ionic build ios" I get following error. I cannot find a log file or any other error to debug this. How do I go about fixing this?
Check your Gulp version and gulpfile.js. You may need to remove the calls to gulp.src
See:
Gulp TypeError: Arguments to path.join must be strings
and

ok, after lot of looking and searching I figured my npm install was messed up.
Part of my installs were in /usr/local and few of them were in /User/user.name/npm folders. /Users/user.name/npm was set in the npm config prefix.
I had two installs of cordova, one on each folder above. Some how the cordova from /usr/local was getting used to create the project and that was the old version.
To fix the problem, I uninstalled all my global npm installs and pointed my npm config prefix to /usr/local and gave myself execute permission on that folder. Everything is working now.
Here is the video that explains how to do it: https://docs.npmjs.com/getting-started/fixing-npm-permissions
I am trying to compile Spark IDE for chrome apps from https://github.com/dart-lang/spark/tree/master/ide. Steps
Opened chrome://flags and enabled experimental api
Opened chrome://extensions and "Load unpacked extension" pointed to the local folder for the above code.
The app loads. On loading it is stuck with a loading animation forever
For running in Dartium you need to point to the app directory not the package directory.
You also need to run grind setup to copy the application to the app directory as the readme here says https://github.com/dart-lang/spark/tree/master/ide
I'm not sure this experimental settings are still necessary (probably not if you use a Dart development build which already includes Dartium 36)
For building to JavaScript you run pub build in the package directory and load the extension from build/web/app (normally it is done this way, not sure if this really works with Spark, haven't tried it myself yet)
