Dart editor was working fine with a polymer app that I was developing previously.
I have rebooted, reinstalled dart editor with no luck
Running Pub Get manually fails as well as it can't find files either. Evrrything was working prior to trying CDE and the designer.
I think running pub cache repair (run in command line interface) should be able to fix this.

Question: How can I solve the flutter error as shown below & why does this happen?
What I can't understand out of this error, is
that I can't comprehend what #dart=2.9 is. I hadn't previously run or coded the file in a while. So, when I came back to work on this flutter file project, it threw me this error?
I tried updating flutter on the command prompt. Everything it's fine according to the flutter doctor. The only missing piece is just visual studio, but I use visual studio Code. So, I am assuming that's not the problem. If not, then what could it be? I am deeply thinking about this long error, that can't get to comprehend.
Much appreciation in advance any sort of help will be gratefully appreciated

I have previoulsy tried updating flutter on command prompt. Everything it's fine according to flutter doctor. I have tried looking on what #=dart=2.9 is? but not enought understanding still. I have also tried looking on something the error highlights which is 'dart:html'; still, I don't comprehend how and why that is an errors?
1-just delete import 'dart:html'; from your code
2-run flutter clean then flutter pub get
if that doesn't work check this
I am trying to use PHP_CodeSniffer in my Hack project. I tried getting the phpcs.phar file from the repository and run it, but I get an error, something that seems to be a bug of HHVM (see #5140). So I tried building it to .phar myself. I ran the most obvious script:
scripts/build-phar.php
so
$ hhvm ./scripts/build-phar.php
This is the output I get:
Building phpcs phar
=> /devel/phpcs/phpcs.phar
Fatal error: Uncaught exception 'PharException' with message '/devel/phpcs/phpcs.phar is not a file' in /devel/phpcs/scripts/build-phar.php:43
Stack trace:

#1 {main}
I am not sure where to look or what to look for here. Could you please give me some advice on building a .phar from this?
On a fresh flow install, that is after copying my existing site and launching "composer install" with sucess, when I execute the "flow" command, I obtain the following error:

I'm really out of clue here on what to do or what's causing this issue. Nothing was found on the web either.
I had to delete the PackageStates.php file and then everything worked fine.
I’ve had this issue recently, too (and so did a colleague). Deleting Packages/Libraries/doctrine/common and running a composer install fixed the issue.
I am using Dart Editor|
Dart Editor version 1.10.0.dev_01_01 (DEV)
Dart SDK version 1.10.0-dev.1.1
I open polymer_snippet and run the app and it executes as expected.
I attempted to run epimss_app but it does not run and displays the following errors to Tools Ouput (console)

This is an unexpected error. Please run
pub --trace 'serve' 'web' '--port' '8080' '--admin-port' '49923' '--hostname' 'localhost'
and include the results in a bug report on http://dartbug.com/new.
I tried to run polymer-snippet again with the same result. I closed Dart Editor did a pub cache repair and attempted running either application again with the same result.
The GUI (if dart-eclipse-editor is used) says Error Launching application - Could not start pub serve or connect to pub.
Why is this happening? I would expect to be able to change from one dart app to another and run either without any issues.
Thanks

The editor recently started adding a --machine flag so that build scripts would know to output machine readable messages. web_components added support for the flag last week, have you run pub update?
