Dart syntax highlighting is not working in vs code - flutter

i have been using vs code for flutter for 3 months and now i got into this issue
syntax prediction works and flutter run is also working but syntax color is gone
Also i have uninstalled every extensions and reinstalled vs code
here is the console screenshot

It appears that one of the files in the Dart extension may be corrupt on your disk (syntaxs/dart.json). I would try to uninstall the extension and re-install it.
If that does not help, please check the contents of the .vscode-extensions folder in your home directory in the Dart-Code folder syntaxes/dart.json and see why it is not valid json.
I've seen this once before (https://github.com/microsoft/vscode/issues/73134) though it's not clear why it happened.

PHP Extension is missing in my vs code and my PHP will not run

I deleted an extension from my vs code and PHP was gone after that. I have not been able to run script since and I have no idea how to get the PHP extension back. Any ideas how I can do this? Uninstall/reinstall did not resolve the issue.
I uninstalled/reinstalled the app and nothing changed. I found the settings were the same as before I uninstalled it. I have vs code installed on multiple machines and the sync is turned on.
Screen shot from my VS Code

Command 'Flutter: New Project' resulted in an error (command 'flutter.createProject' not found) and i cant debug flutter project on VSCODE

I have a question. I am using vscode and yesterday VScode is broken and deleted and re-installed But when I debug my project in vscode, there is no response and the computer does not show any error. I couldn't understand where there was an error.I would be very happy if you could help. I cannot progress in the
project, please help.enter image description here
I had the same problem and solved it by doing:
Uninstall VS Code dart and flutter extensions and close VS Code.
After this go to: vscode\extensions and remove all the files.
Run VS Code As Administrator.
Open VS Code and install dart and flutter extensions.
The cause for me might be that when you uninstall an extension files aren't erased.
I hope I helped you
Install 'Recommended' to the current extensions (shown at the bottom right when you launch VS ). This resolved mine.

How can I get VS Code Flutter mode working again?

My Windows machine crashed while VS Code was updating itself. Now Flutter/Dart mode no longer works, i.e. no syntax coloring or intellisense, no debug support etc.
I have a) deleted the VS Code cache (AppData/Roaming/Code/Cache) b) reinstalled VSCode c) reinstalled Flutter and Dart extensions, but no joy. Flutter doctor says everything is OK.
For what it's worth, Python mode still works.
Has anyone seen this?
I deleted the Flutter and Dart extensions on disk in the dart-code.* folders in %USERPROFILE%\.vscode\extensions, resinstalled the extensions, and everything is back to normal.

VS Code and Flutter/Dart, Widget Autocomplete not working

I'm working with some tutorials to learn Flutter and the one that I'm taking now uses VSCode. I actually prefer it to Android Studio because it doesn't overheat my Macbook. The only frustration I've had with it so far is that there are quite a few times where autocomplete just stops working. For instance, if I wrap a Column in a widget and then start typing Container, Android Studio will pop up an autocomplete showing Container VS Code used to do this for me, but has stopped for some reason. I can still get the autocomplete list if I press Ctrl+Spacebar.
I'm using the following:
VS Code - 1.36.1
Dart Extension - 3.2.0
Flutter Extension - 3.2.0
Material Icon Theme - 3.8.0
This is the latest version for all of these.
Is there some setting or something that I need to change? I've spent the last two hours trying to work out what's going on. In searching, I did see some references to earlier versions of VS Code and the extensions causing problems, but nothing about these versions.
Go to pubspec.yaml and hit save or run get packages. It worked for me, hope it helps
There are generally two reasons for VS Code to automatically open code completion - 1) when you press a key that the extension ahs told VS Code should invoke it and 2) when VS Code thinks it would be useful (for example when you start typing on a blank line). If you're typing in a line of existing code it won't always do this.
Pressing Ctrl+Space is the correct way to open completion in the cases where it doesn't appear automatically.
That said, if you can provide more information about a specific instance, I can take a look if it's something we could/should pop completion open for. It would be best raised at https://github.com/Dart-Code/Dart-Code/issues with a screenshot and details of exactly where your cursor is (and how you got there).
dont use too many flutter extension, I also face this problem , then I realize that 3 flutter extension are installed, use only one , it works for me, try it.
I did have a derivative of this problem when I was working with VS Code and flutter and this is what I did.
This is for windows though. This is what I did ;
Go to C:\Users<your username >\AppData\Roaming\Code and delete all the files and the directory called "Code". Usually the folder AppData is hidden so you'll have to unhide it. Then restart your computer and then reopen VS Code. This I think cleared some of the unwanted cache files which kind of made things right again.
Hope it helped.
Make sure
Preferences > Editor > Intentions > Quick assist powered by the Dart
Analysis Server
is enabled (Screenshot).
If so, most likely your Dart Analysis server is crashing. Navigate to your HOME folder:
cd ~
And then below should resolve your issue:
sudo chown -R $USER .dart .flutter
Clear your cache if the issue still exists:
File > Invalidate Caches > Clear file system cache and Local History > Invalidate and Restart.
Also, Power Save Mode should be disabled:
File > Power Save Mode
Doing a flutter clean and then flutter pub upgrade worked for me. Sometimes flutter clean using the command line does not work if you have android studio then in tools go to flutter and then do flutter clean.
just do flutter clean then flutter create. and then flutter pub upgrade, and also see if your flutter SDK is latest or not.
Check to make sure Android Studio is not on low power mode
Menu>File>Low Power Save Mode
I solved in in my Macbook Pro by
Going to System Preferences > Keyboard > Shortcuts > Input Sources
Disable: Select the previous input source (^ space)
Updating VS Code dart and flutter extensions
Restarting the computer.
And voila! Ctrl + space now shows options in VS Code.

Receiving error message 'Extension host terminated unexpectedly.' in Visual Studio Code

I have been looking around and I haven't found any answers to my issue.
I keep getting this error "Extension host terminated unexpectedly." and I have tried removing all of my extensions, reinstalling the program, trying different versions of vscode including the insider versions.
The way I get this isssue isn't from trying to use the debugger or trying to use some sort of extension, as I said before I removed all of them and the error keeps on coming back, it's simply from opening the application. I'm not entirely sure how to continue? I have had to use another editor because the error just doesn't go away. I will just have to wait for another update of Visual Studio Code I assume? I've had the issue since tuesday this week, guessing since the latest update.
Above is the error message I get. It is closed by esc but reappears very shortly after, every time.
When I open developer tools, this is what I find in the console.
Running vscode from command prompt with Code.exe --disable-extensions doesn't help.
Visual Studio Code version: 1.16.1
I appreciate any help.
Linking my github issue on Microsoft/vscode as reference
I had the same error after updating vsc to v. 1.31.0.
Disabling Live Server Extension worked for me.
Here's the error i'm getting having the extension enabled.
I started getting this error when vscode automatically updated to March 2020 (version 1.44). I have tried various suggestions given in the forum and over the internet but none of them worked.
What worked for me: I downloaded January 2020 (version 1.42) build from https://code.visualstudio.com/updates/v1_42 and ran over the previous installation without uninstalling and surprisingly, the error disappeared and all extensions are loading and working properly.
I tried following things and non of them worked:
I disabled all the installed extension from GUI.
uninstalled all the extension and installed again.
removed the left-over extensions from Windows %USERPROFILE%.vscode\extensions.
tried launching from the command prompt with --disable-extensions option.
Linking my github issue on Microsoft/vscode as reference.
It ended up being one of the base extensions that runs on startup that was the root of the problem.
In my case the git in extensions folder was causing it.
"git.enabled": false was not doing the trick so I had to remove the git folder altogether for the error to disappear.
In my case, I used typescript-hero extension. Disabling this extension fixed my problem.
It's temporal fix but maybe will help somebody.
I disabled all the extensions with name Live for example Live Server, Live Share etc and restarted my vscode again and it worked for me.
For me this was happening due to HTML CSS Support extension. so i removed it and restarted vs code and voila! it worked!
I had to uninstall few extensions related to Java (debugger for java, Test runner for java, extension pack for java etc) to make the error go away.
Click on the developer tool option that popups and see if it has the extension which is causing this error.
I got same issue and it was because of Color Highlight Extension. I just uninstalled Color Highlight Extension and its working fine and NO ERROR.
Me too. My failure has no "Code":
Extension host terminated unexpectedly. Code: null Signal: SIGABRT

I recently ran into the same error message after accepting a permission to run a program on the extension livepreview. It corrupted all other extensions where it could not find the commands. I deleted all extension files and reinstalled the other extensions without a problem. I tried liveserver again but It never prompted me again for permissions and still, the error message keeps occurring. I'm assuming liveserver was trying to ask the computer permission to run a local server after which is still accepted but something else is interfering with the computer being able to translate from the program to actually building and accessing the local server.
In my case, the live server extension was causing this issue in 1.31.0v of VS Code. After uninstalling the extension it started working correctly.
In my case it was from the extension "Todo Tree". It was breaking on a particularly large file in my project (13.7mb), with the error saying the file was over the max-size for a node-buffer (used by the C regex matcher).
Resolved the issue by disabling the extension.
I also opened an issue for it here: https://github.com/Gruntfuggly/todo-tree/issues/135
I had same problem with following error in my VSCode console.
`1: node::DecodeWrite
2: node::InternalCallbackScope::Close
3: v8::internal::VirtualMemory::TakeControl
4: v8::internal::PerThreadAssertScope<4,1>::PerThreadAssertScope<4,1>
5: v8::internal::operator<<
6: v8::internal::operator<<
7: 00000073ECF04481`
I solved it by uninstalling Angular Console extension. Not sure if it was that particular extension or some other memory issue but problem went away as soon as I uninstalled that.
Remove all Extensions which are located in a per user extensions folder. Depending on your platform, the location is in the following folder:
Windows %USERPROFILE%\.vscode\extensions
macOS
~/.vscode/extensions
Linux ~/.vscode/extensions
Restart vscode and start installing extensions.
I am not sure why this caused , but the Antivirus was throwing popups that something like extensionprocess.js file was repaired.
Disabled the Antivirus and re-installed Vscode and it was back to normal.
Hope this helps.
Here is what helped me:
Ctrl+Shift+P --> type: "Disable"
and click Disable all installed extensions
(alternatively click Disable all installed extensions for this Workspace)
Then go to extensions panel on the left and re-enable slowly those that you really need.
See which extension (or their combination) triggers that error.
It will be highly appreciated which extenstion/combination you'll find guilty as there may be several of them, and different in time...
for me, it was code runner extension I just disabled it.
