I was programming in Flutter as normally today and suddendly it started giving me the following error:
sry for german language
it states that in line 1 symbol 1 of calling flutter.bat, because it couldnt be found.
The program is terminating
Flutter gives me the same error, if I call it from the Console, even shutting down the console if I try to call flutter --version from Console with Admin rights.
The Flutter console flutter_console is giving me the error that flutter_console.bat doesnt exist.
I redownloaded Flutter, changed the system Variables and also downaloaded an old version of flutter. Still nothing is working.
I hope someone can help me

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 made an app in Flutter and there are no errors on its Dart file but I suddenly end up with errors on widget_test.dart. can you guys help me out. Thanks
Run flutter clean, and then flutter pub get in the terminal respectively.
If that doesn't work, try running flutter upgrade, and then repeating the initial steps.
Finally, if it still isn't working, you can run flutter doctor to see if there's anything glaringly wrong with your project.
I have searched the internet but cannot find others with the same problem. Does any one know how to fix the below error?
After updated XCode to version 14.0, my Flutter app failed to build. I have found out that the problematic package is html_editor_enhanced. If I remove it, then the build is successful, but I need it for allowing WYSIWYG editor. I see that it depends on another package called flutter_inappwebview, so I added it, but to no avail. When I try to build, the error in VSCode is:
Swift Compiler Error (Xcode): Cannot find 'webviewController' in scope /Users/<username>/development/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_inappwebview-5.4.3+7/ios/Classes/InAppWebView/FlutterWebViewFactory.swift:32:8 2

And in XCode, the error is:
Cannot find 'webviewController' in scope
Below is the screenshot from XCode.
running the following command fixed the problem:
flutter pub cache repair
May I ask your help about this error
It's happen when I'm trying for the first time running my flutter web which using flutter run -d chrome
Launching lib\main.dart on Chrome in debug mode...

And if I trying run using
flutter run -d web
It's doesn't thrown any error but on the website it goes blank white nothing shown up.
Anyway thanks for your help
adding the following in the pubspec.yaml worked for me. I am using beta channel.
dependencies:
dwds: ^16.0.1
then run command:
flutter update-packages
I was also facing the same issue, I don't know the exact root cause of the problem but I have a hack to make it work.
I was facing the issue after I deleted .pub-cache folder, so from my recycler bin I picked dwds-2.0.1 folder and reverted back. This hack working
add dwds package in your dependencies and run flutter update-packages. It will work :)
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.
