Issue
I constantly see a message when running my Flutter projects on web:
You are using unsupported command-line flag; --disable-web-security. Stability and security will suffer.
This issue started from this answer, because I set this flag on development (later it turned out it's only working on dev, but not on production).
What I tried
Undoing the changes discussed here
restore the deleted file named flutter_tools.stamp at flutter\bin\cache
remove the added line from flutter\packages\flutter_tools\lib\src\web: '--disable-web-security'
dart pub cache repair
flutter clean
restart computer / Vscode
None of the things worked that I tried. Should I reinstall the whole flutter or is there something simpler I can try?

So basically the problem is that I created a new flutter app, and the I opened the emulator(from android studio), and I clicked on run.
I had multiple problems that were related to heap memory and such, but I managed to solved most of then using all kind of methods from the internet.
I even deleted and installed Java and android studio multiple times, I changed the Enviromental Variables as the Internet suggested, but now, the current error that I get is this:
The Error Image
my flutter doctor -v:
flutter doctor -v image
I'm about to lose my mind, I'm on this issuse for a few weeks. please help me fix it
after your seggestion to add "gradle.properties" and adding "org.gradle.jvmargs=-Xmx1024m" to it (without the " "):
after
Perhaps you shoud add a line at end of file gradle.properties org.gradle.jvmargs=-Xmx1024m then clean the project, also validate cache and restart the android studio. It should works then.
My App have a Problem so I Need to do flutter clean before I can debug my app.
So I do flutter clean and after that flutter run in my Terminal.
Then my App debug. After that flutter creates a new build folder, new .flutter-plugins and .flutter-plugins-dependencies.
Now I think the problem is not there but sometimes it creates the files.
Can I delete the files? And how can I fix it?
PS: I have the newest version of flutter and Xcode. And I work with VSCode and I work on a MacBook with the newest Version.
I'm not sure about this, but in one case I tried adding resource permission from info.plist(I messed with internal storage permission), I noticed similar behaviour.

Worked for me on beta as well. It's a bit less cutting edge than dev so might be better for some uses.
flutter channel beta
flutter upgrade
Also found out that turning off the previewLSP setting in the VSCode Dart & Flutter extension settings turns the refactoring menu back on. There seems to be a disagreement between LSP mode and refactoring that is fixed in later versions. If you don't want to upgrade you can try turning that setting off and then restarting VSCode.
Run flutter doctor, if flutter and dart are up to date then try switching to a different flutter channel and update flutter and dart again. It worked for me recently.
Try switch to dev channel,
flutter channel dev
flutter upgrade
I sugest to re-install the flutter plugin for VSCode (wich includes dart). See if it helps.
the dart path is correct, the environment variable also fine but I can not figure what went wrong, I can not create or run flutter projects. I don't know what is the is please help me figure out this.
There could be chances that you've installed a Flutter before and Flutter took parts of the old version to initialize. Here is a related GitHub post.
Usually a workaround here is to remove or delete flutter_tools.stamp.
rm FLUTTER_ROOT/bin/cache/flutter_tools.stamp
But for most, replacing the existing Flutter SDK with the new one from the Flutter website works like charm.
I know it maybe still early but I want to try and use full flutter existing cross-platform support in one project. Stability is not my main concern.
I have started a flutter project in android studio. Naturally I have (android/Ios) going smoothly. But I would love to add Web and desktop to the same project.
Please help me with and direction, or if there is solution any one has created however much experimental.
There is a migration guide for web here. I got it up and running on a very basic existing app.
Best way is to do it in a separate branch since it requires changing packages and I even deleted .packages and pubspec.lock files first. Then I ran pub get (not flutter packages get) to download the required packages and run some precompilers.
