This error is showing all of a sudden when I opened a Flutter project. When I tap the editor, this message is showing,
Also, the editor is not suggesting anything, not even error messages.
The last thing I did was installed the GitLens extension and initialize a repo for the first time.
Reinstalled VS Code and disabled all the extensions still no result. Can someone help me with the issue?
VS code version: 1.59.1
Flutter: 2.2.2
Dart: 2.13.3
I just updated my flutter with the flutter upgrade command. Now my version is 2.2.3 and it has solved the issue.

Not sure which details are relevant so I'll include as many as possible.
Had to upgrade flutter today and instead of working when I typed in 'flutter upgrade' into android studios terminal/Iterm2/terminal zsh I was met with the following response.
'sysctl -n hw.optional.arm64' returned unexpected output: ''
When I search for this issue the only thing i can find is this post which states that sysctl can't be found. The path does appear to be in my .zshrc but still not working. I can't use which or where sysctl as it just says 'sysctl not found'
When I try to upgrade flutter through brew (brew install --cask flutter) it downloads fine but on installing it throws the following error:
==> Purging files for version 3.3.5 of Cask flutter
Error: It seems there is already a Binary at '/opt/homebrew/bin/dart'.
I can't continue working as I need the new flutter version and it seems the web doesn't have much to show for this particular error.
I can't flutter --version, flutter doctor or anything of the sort as I just get the same message.
I'm using:
MacOS monterey 12.6 macbook air.
Android studios
Iterm2
Ohmyzsh
When I open android studios it shows me the following:
"Flutter device daemon #1 exited (exit code 1), stderr: 'sysctl -n hw.optional.arm64' returned unexpected output: '' in a pop up window.
Pubspec has been edited > get dependencies > Upgrade depenedencies: Both of which have the same error as in the title.
The current configured flutter SDK is not known to be fully supported. Please update your SDK and restart intelliJ which I think is what I've been trying to do.
This is an answer I hope will be helpful for others who have the same issue.
Other answers suggested a fix by just updating the path document (.zshrc) but this is what helped me as that did not and my paths were up to date.
Sadly, it's as simple as manually deleting all my flutter SDK files locally. Downloading them again (this time the latest one) and unzipping it into the same place. Didn't even have to update the path).
Worked a charm, issues appear to be all gone except that the dialogue in android studios is still saying that there are dependencies that need getting and upgrading (but doesn't go away even when I've run it).
I solved it by removing the old flutter SDK, downloading the latest version, and setting it up again.
it works perfectly for me!
I get an error message while running a Flutter project. I tried using webview_flutter(1.0.7) plugin with Flutter 1.22.5(stable) and Flutter 1.26.0-2.0.pre.167.
This is a fresh new project with only webview_flutter plugin dependency.
I am getting the above error that package webviewflutter does not exists.
Please help to solve this issue.
You may want to check if you made the correct entry for the package in your pubspec.yaml and after that does get run successfully.
Just a tip:
It is better to paste the error text, rather than a screenshot.
I update the Flutter latest stable version 1.20.1 when I click the run button on an already existing project it shows me this error:
Could not resolve the package 'characters' in 'package: characters/characters.dart'.
But when I create a new project and try to run it works.
Following the Github issue below, it is a common issue after upgrading to a different Flutter Version
Could not resolve package characters
In my case, I resolved the issue with flutter clean.
I'm running a dart only test in intellij and receiving the following error:
The pubspec.lock file has changed since the .dart_tool/package_config.json file was generated, please run "pub get" again.
I have tried pub get a number of times. Any ideas? I'm on the dev branch of Flutter (anything using Dart 2.7 pretty much fails with the same or a similar error message).
Edit
I think that if you have a path reference dependency in the pubspec.yaml file it will fail.
Anything like the following fails with the above message if you try to run a dart test in IntelliJ.
dependencies:
test_dependency:
path: ../test_dependency
I'm not suggesting this is a fix for everyone, but it did resolve my particular situation.
Just ran into this error after upgrading flutter from 1.22.6 to 2.0.2 and trying to use build_runner: ^1.12.2 and json_serializable: ^4.1.0 to generate json serialization/deserialization classes & methods.
The problem is apparently related to the pub package when used with relative paths for packages as noted in the following github issues:
https://github.com/dart-lang/pub/issues/2806
https://github.com/dart-lang/pub/pull/2830
One of the commenters in issue 2806 mentioned running flutter create . inside the flutter project folder which rebuilds .dart_tool/package_config.json, adding any missing entries, solving the problem.
No one solved this problem so far?
I've found a staightforward solution and it works fine for me.
You need to close your IDE (VSCode in my case), make sure that is completely closed using process-monitor.
Then open a terminal window manualy in your project folder and run "flutter pub get"
After that just start your IDE normaly and ewerything will work fine.
when i create a new flutter project in vscode it will immediately shows an error in the main.dart file and gives a gradle error when trying to debug.
shown here: main.dart error
"compiler message: lib/main.dart:68:19: Error: Too few positional arguments: 1 required, 0 given."
I've reinstalled dart and flutter plugins. updated the java install.
in debug console i get this:
debug console
added output of flutter doctor -v
enter image description here
I was also facing the same error, but it was always on my test folder.
This is what I did:
On your terminal, make sure you are in your project repository.
Run the flutter pub get command, it worked for me, may be you
should try it too.
Do you possibly have two different versions of the Flutter SDK on your machine? I wonder if one is being used by flutter create and the other for analysis.
If you're sure you only have one, please open an issue on GitHub and attach a log file for me to investigate.
