I have made a rough Flutter webapp (I am really new to this), when I test it through VS code, the app works just fine but I have been unable to upload it online. After I committed the app to a git repository, the link shows nothing but a blank page. When I try to open index.html from build\web\ I get a blank page again.
Expecting the code to work locally as it did when I run it through VSCode. I can see the code is working when opening through VSCode (-d chrome) but after 'flutter build web', the generated index file is only showing a blank page. I tried hosting it on Git but I could only see a blank page then as well. While hosting on git, I changed the text and yet it did not work as expected.
The error is only in Console and here it is:
Console Error
Flutter Doctor shows no issues at all and I have also tried changing

I have downloaded live server but it is not working. It doesn't show me any error messages like it does to others. I tried reinstalling it, I tried reinstalling vs code too, but nothing happened. I see from people which have it working that it displays on the tab of the IDE but for me it’s not there. I try to open it with right-clicking on one of the HTML files but nothing happens. I also checked my default browser and added it to the json.file.
I just decided to install an earlier version of the live server extension and it worked.
recently I installed a fresh version of the KDE neon user edition and I updated it and works fine.
I also installed the vscode Debian version and nothing is wrong.
but when I want to login with my GitHub account in vscode for configs sync it opens a firefox tab that I log in to my GitHub and authorizes the vscode and it succeeds and gets back to vscode and instead of signing in and syncing the configs it opens an empty unsaved file named something like this:
did-authenticate\?windowid\=1\&code\=6beea2fcb8a47e0ea49e\&state\=2efc5efd-9c68-4735-a4a0-fd690dd7aec0
in this path : "~/vscode:/vscode.GitHub-authentication"
and after a few seconds canceled notification appears.
I've installed vscode for Debian version 1.63.2 which people in this Github issue had the same problem in version 1.62.2 and they are saying that this problem is fixed for them in version 1.62.3.
I don't have this problem with the Microsoft account sign-in.
what am I missing?
Update:
for testing, I tried to install an extension for vscode and I pasted the URL with vscode protocol in a web browser like this (vscode:extension/GitHub.vscode-pull-request-github), and instead of opening the vscode extensions tab, it goes back to vscode and opens an empty file in the same directory ("~/vscode:/vscode.GitHub-authentication").
so this is vscodes fault that cant handle the vscode: URLs.
I found out what the problem is but I don't know how to fix it
for the record I've updated the vscode today to the 1.64.1 version and still have the problem.

First, you need to get the GitHub Pull Requests and Issues and GitHub extensions together. Then go to the section specified in the photo and give the details of the account and repository you are using. And then it will be fixed.
I ran into this issue myself and discovered that it's because the VS Code command-line application isn't designed to handle URLs, but local file paths. VS Code registers the vscode:// URL scheme with XDG using an appropriate *.desktop file and these URLs should be opened using the command-line program xdg-open. In Firefox, if you have not yet set a default application for vscode:// URLs, then it will ask you for a program to open it with, select /usr/bin/xdg-open. If you have already set it to a different default, you can change it as follows: go to the Menu -> Settings -> General -> Applications -> vscode -> Use other... -> Select /usr/bin/xdg-open as the program for vscode.
With the default for vscode:// URLs set to use xdg-open, then any future integration with VS Code should work naturally to open it as expected.
I changed nothing, just worked on my Flutter Aplication, after the day i wanted to flutter run --release my app, but it didn't worked and i got this error message: Target file "lib\main.dart" not found. The day before everything worked fine. After a couple of times i tried it on another app, where i didn't changed something for a couple of days. But some of my other apps are working fine. The normal running in Android Studio is working normally on every app. Does anybody knwo what's the problem here?
My Error
My Directory
You are probably running your command on a different directory. Check your directory using pwd command on terminal.
Edit: As you use windows, make sure you open command line in your project directory.
See this tutorial.

Connecting to VM Service at ws://127.0.0.1:52373/PSOLWnX5IdE=/ws" error is come in debugging of flutter code in VScode, please tell me how to fix it
Close your current project and run any different and see if it runs. In my case I was getting the same error, so I open a new project and guess what it ran successfully. So I removed my project that was not working and cloned it again. There was no error this time.
I'm new to learning flutter when I try to crate a new project on android studio gives me a arror message in the event section enter image description here
The MESSAGE: [Could not find an option named "platforms". Run 'flutter -h' (or 'flutter -h') for available flutter commands and options.]
And another problem is flutter doctor does not see the android studio enter image description here
1(By the way, I want to use this version of flutter, please do not give a suggestion like update.)
2(this problem did not exist before, it happened after turning my computer off and on)
And sorry for my english mistakes
Thank you.
flutter version flutter_windows_v1.12.13+hotfix.9-stable
andorid studio version: 4.1.3
Is this the answer to your question about andorid studio?
and you need to install JDK
You are using the wrong flutter SDK. Too low information in your question. Make sure that you have the right path to flutter SDK in your IDE. Check that the flutter SDK directory has the appropriate structure, all needed files and cetera. Channel and version of flutter also may have an influence on this problem.
Got this today out of nowhere. Things were going well, but suddenly when I tried to relaunch the app from fresh, for the error Could not find an option named "target"
UPDATE:
This appears to happen when I switch branches and merge while app is running/flutter is attached. If you're using VS Code,
open your launch.json
change something, I decided to change type: "dart" to type: "notdart"
save
try to debug which fails
then revert that change.
This should fix the issue.
Previous Answer/If you're not using VS Code
What worked for me was to
flutter clean
close the editor (VS Code for me)
close the emulator
give a minute for things to close down
open task manager and kill any left over processes of dart.exe flutter.exe and java.exe and adb.exe (was doing Android)
start VS Code/Android Studio and try to debug again. (when prompted I chose to cold boot the emulator as well)
This takes a while as the emulator has to cold boot and since flutter clean was run, the compilation hadto start from scratch as well.
