In VSCode and trying to run the following:
dart pub upgrade
I get the following error:
Error: Error when reading 'pub': No such file or directory
However, my flutter file seems fine. Flutter Doctor output below:

Any idea how I can resolve this? Thanks!
first clean dart using dart pub cache clean
then run dart pub get
After that run dart pub get upgrade
try creating a .bashrc file in your user's folder.
Then add the following:
PATH=$PATH:/path/to/dart/installation/bin/folder
export PATH
This can happen when you have installed Dart-sdk two times. One time as a windows installer, and the other through chocolatey for instance. Uninstall the one you have in "Add/Remove programs", or at least make sure you only have one, and it should work.

Flutter doctor showing issues at IntelliJ Idea. How can I fix this issue?
I had the same problem. In my specific case I simply:
Downgraded to version 2021.2.4
Cleared the download cash.
Restarted my machine
At this point, Flutter Doctor was no longer returning an error. (But I was in the old version of IntelliJ IDEA).
Then I reinstalled the new version 2021.3.
Cleared the download cash.
Updated all plugins, invalidate caches and restart.
Upgrade Flutter to 2.8.1.
Restarted my machine.
Now I have no more errors.

There are few step to follow that may help you
Close the editor
Go to console
Set the path of your Editor to flutter directory by using this command
flutter config --android-studio-dir="Path of your code editor"
make sure that you have double quotes around the path.
I am trying to create icons for my app using flutter_launcher_icons, with options defined in pubspec.yaml. When I run flutter pub run flutter_launcher_icons:main, I get the following error:
Unable to spawn isolate: error: Library 'file:///Users/cameron/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_launcher_icons-0.9.0/bin/main.dart' was compiled with sound null safety (in strong mode) and it requires --sound-null-safety option at runtime
pub finished with exit code 1
Even if I pass in --sound-null-safety, the error persists (I also tried '--no-sound-null-safety' which also did nothing).
To check it wasn't a configuration error, I ran flutter create <name>, added flutter_launcher_icons: to dev dependencies (and flutter pub get), ran the same command and got the same error.
I am on Flutter 2.2, and I depend on integration_test, so I can't downgrade to a pre-null-safety version of flutter_launcher_icons, because those versions have transitive dependencies that conflict with integration_test from sdk.

I am trying to migrate my Flutter/Dart project to use null safety. I have updated all of my dependencies and changed the sdk to use ">=2.12.0 <3.0.0". However, when I try to use the migration tool I get the following error:

I'm suspecting that maybe I don't have the latest dart sdk like I believe I do. If that's the case then how do I upgrade without breaking anything?
UPDATE:
It appears I am using the latest version of dart. Going into the settings in Android Studio I can see it is pointing at the dart sdk that ships with flutter:
Have you run "flutter upgrade" in your terminal?
I am running flutter doctor command. But it is saying android studio is not installed many times. I tried flutter config --android-studio-dir=/home/khamidjon/.android, and many more paths I tried to show but to no luck.

My question is what location should be shown for PATH in flutter config --android-studio-dir='PATH'?
For Android Studio installed with Flatpak, i found this config to work:
flutter config --android-studio-dir=/path/to/home/.local/share/flatpak/app/com.google.AndroidStudio/current/active/files/extra/android-studio
Where path/to/home is the path to your home directory.
(Ubuntu 21.10/Pop!_OS)
Snap packages are installed under /snap/appname/ with subdirectories for each new version. Try this to reslove the issue, it worked for me.
flutter config --android-studio-dir="/snap/android-studio/current/android-studio"
The current directory will make sure that it always points to the latest version.
if you have Androind Studio installed in your home directory /home/khamidjon set up PATH like this: /home/khamidjon/android-studio/bin
to append variable in Linux use command
export PATH=$PATH:/some/new/path
to check your PATH use
echo $PATH
In my case snap packages can retain old versions of the program. So inside /snap/android-studio There were 2 versions of android studio inside directories /snap/android-studio/99 and /snap/android-studio/100. So I showed one of these paths: directory /snap/android-studio/100/android-studio with latest version.
So I ran:
flutter config --android-studio-dir=/snap/android-studio/100/android-studio
flutter doctor

Note: for those who are facing the problem in Ubuntu and Android Studio is installed with snap:
flutter config --android-studio-dir="/snap/android-studio/current/android-studio"
Note: for those who are facing the problem in Ubuntu and Android Studio is installed with JetBrains Toolbox:
flutter config --android-studio-dir=/home/myuser/.local/share/JetBrains/Toolbox/apps/AndroidStudio/ch-0/201.7042882
Where ./201.7042822 matches the current version of Android Studio installed. You'll have to check which one you have and update it in the command above.
