In the image above you can see that the whole dart code is showing white lines and this happened after my laptop accidently turned off while I was running the code.
The first error it gave was corrupted .git/packed-ref file which i fixed but this one isn't going away, other file type is showing their repective color theme only the .dart file is doing this. and also dart analyzer isn't working too

I don't exactly know what the problem is, since it isn't showing me any error. Please what do i do?
I think there is something wrong with the Dart extension (perhaps some files are corrupt), but uninstalling/re-installing it does not remove the files from disk and re-download it.
I would try uninstalling the Dart extension, then go into your %USERPROFILE%\.vscode\extensions folder and delete any dart-code.dart-code folders, and then re-launch VS Code and re-install it.
If that doesn't solve it, please file an issue at https://github.com/Dart-Code/Dart-Code. Thanks!

So this project of mine had flutter_blue plugin in it. And I just switched to flutter_blue_plus. And now I can't run it on my system. And this is the error it shows. And when I checked, it feels like no one else is facing this issue. There's no mention on the flutter_blue_plus package issue list either. And i found some of the similar kind of problems on stackOverflow from years ago. And it seems like they're just android problems. And I'm not an android developer. Another known flutter developer faced the same issue with the original flutter_blue package on M1 pro. And on his device, flutter_blue_plus runs properly. I'm using Windows 11 for my development.
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':flutter_blue_plus:generateDebugProto'.

I've tried the basic steps, like cleaning and rebuilding project. And here is the device speceficaiton im using.

If someone is facing this problem. Or anything that looks familiar to it. You can try checking your gradle.properties file inside your projects android folder. And if there's any line that looks like this
protoc_platform=osx-x86_64
Try removing it.
To my little bit of understanding it's just saying the gradle system to look for the macOs operating system while creating the protoc buffer. And it's not finding it bcz the platform is windows. At least in my case, it was. It can be vice versa.
Recently (today) I tried to create an app for web and desktop with Flutter and wanted it to be in multiple languages (English, French, Arabic, Dutch...) so I looked at Flutter's tutorial and followed every steps it had. And just after finishing the last step I had it working ! I could add text in, English in the app_en.arb file and in any other language in app_fr.arb by example. When I hot reloaded/restarted my app the Dart files it generates are rebuilt. But now when I do that I have an error that I couldn't find anywhere else on Internet:
Exception: Found syntax errors.
And the dart files for localization weren't rebuilt. Now I must use the
flutter gen-l10n
command to rebuild my language files.

it's me again, this looked like a PATH problem in my case. Now that I restarted my computer I don't have the error anymore, I should have checked that before. But as I never saw this error before you should check other things like dependencies versions or your Dart and Flutter SDKs, I am not sure about how it happened so restart your computer and check a lot of things could help fix the problem.
In my case this error had appeared after I renamed the folder where project files was. I fixed all paths with old folder name, but the error was still persist. flutter clean didn't help.
Then in folder named .idea I found few files (.xml and .iml extensions) that contained the old folder's name. After I fixed it the error was gone. Hope will help.
I want to debug the flutter demo application on windows x64 device.but it always fails with 1 error and 1 warning this is my Debug console :

I can debug the demo app on edge, chrome, android without any problem
so What wrong?
The (Microsoft) C++ compiler is raising a warning inside the utils.cpp file:
windows\runner\utils.cpp(52,43): warning C4018: '>': signed/unsigned mismatch
It's configured to treat warnings as errors, so the compile fails with:
windows\runner\utils.cpp(52,43): error C2220: warning treated as error - no 'object' file generated
I don't believe that /WX (warnings as errors) can be configured other than by the build script (which turns it ON).
I suspect one of two things:
The Enterprise edition of the compiler (which you have) is slightly more picky than the Community edition (which I have). You could edit the project file to turn off warnings-as-errors, or add an exception for this warning (more below).
Your compiler needs upgrading. I've got 16.11.something; you've got 16.1.something. Run the Visual Studio Installer again to upgrade it. (For example: I just ran it, and it's suggesting I upgrade from 16.11.10 to 16.11.18...).
Editing the project file
The winapp.vcxproj project file is (apparently) generated by CMake. Edit windows\CMakeLists.txt and change the following line:
target_compile_options(${TARGET} PRIVATE /W4 /WX /wd"4100")
Make it look like this:
target_compile_options(${TARGET} PRIVATE /W4 /WX /wd"4100" /wd4018)
I don't know where the quotes come from; you might need them. Alternatively, remove the /WX bit.
I have a very strange issue. After upgrading Flutter yesterday to the newest version, my syntax highlighting is awfully off. When I open a file, everything seems fine, but as soon as the file is analyzed and the result is used for highlighting, everything breaks.
Correct (for 1-2 seconds after opening the file):
Wrong (after around 2 seconds):
I am using the Monokai Theme for VsCode. I would love to get my old coloring back, as I think the new scheme is outrageously difficult to look at.

Add "editor.semanticHighlighting.enabled": false in your vscode settings.json
In any Flutter app in a TextField widget, on Windows, pressing once the AltGr key will drive Windows keyboard crazy: after pressing AltGr, Windows behaves as if the ctrl key was pressed continuously in any application. (Pressing a simple v behaves like if the ctrl-v was pressed) Just double-pressing the left ctrl key will stop this strange state.
Thus, no Windows application written in flutter can be published because if the user presses the AltGr key, he will not understand why his keyboard will not work in any other application afterwards.
It can be reproduced every time, in every environment. On other Windows too. On other machine too. In release exe version too. E.g. in StaleFulWidget, and a TextField in it.
Could somebody help me to solve this very serious Flutter bug? Thank you in advance.
Windows version: Win 10 Pro 20H2 (build:19042.870) Hungarian version. In Hungarian keyboard the # key is AltGr+v. So users can not type any email address.

As of December 6 2021, this is fixed on the master channel.
If you don't want other projects to be affected, you can use https://pub.dev/packages/fvm to use that channel on a per-project level:
activate the tool, running dart pub global activate fvm in your project directory
run fvm use master
run your app using fvm flutter run, or specify the flutter SDK symlinked in your project folder within the ".fvm" directory for your IDE to use for compiling the app.
