You get this error because "packages get" command attemp to delete file in ...flutter.pub-cache_temp. Delete files manually in this loction, this is may not perfect solutions but it works.

In my case it was a permission problem that error code so I just run chmod command for that particular project's folder and the problem gone. Change permission code as your requirements, in my case it wasn't an important project.

sudo chmod -R 777 .

I had the same problem, when I tried to run the official sample code for flutter web "Gallery".

My solution was to upgrade to master. Run "flutter channel master". But take care, since after running this, you will switch to the master channel. I recommend to switch back to the stable channel, as soon as possible again. Because the master channel could have some hard bugs.

try this, it solved my error,

terminal->flutter clean, then flutter pub get after this, you will get the reason for the error, in my case I was using the latest version of path dependencies(path ^1.8.3), but SDK depended on the path ^1.8.2, so I changed path dependency from path ^1.8.3 to path ^1.8.2, in pubspec.yaml, and the error was solved...

My solution was to run

flutter pub get

it in an external terminal not from android studio

Also I set windows as developer, I ran in terminal and turned developer mode on

start ms-settings:developers

not sure which one helped.

If you have tried all answers here.

You should try this, it worked for me.

(in android studio) Delete the pubspec.lock file in your project.
(in android studio) Execute this-- Tools > Flutter > Flutter clean
Go to flutter sdk folder where you have downloaded it. In my case C:\src\flutter\
Run this below command.

C:\src\flutter\bin\cache\dart-sdk\bin>flutter pub cache repair

After completion run pub get again in your android studio. It should work.

Turning on developer mode solved my issue on Windows 10.

Delete temp folder in pub cache.
Do pub repair flutter pub cache repair.
Turn on developer mode in windows settings.
Flutter clean and delete pub.lock if exist.
Try flutter pub get.

This worked for me.

An easy solution that worked for me on Windows was to run Android Studio as administrator.

After that, the error no longer appeared.

I had a similar situation when I upgraded the flutter version to the new 2.2. As a solution, I ran the command line as administrator (or terminal for linux users) in the Project folder and run the following commands:

flutter pub cache repair 2.flutter pub get

Sometimes newly installed packages could cause this. Uninstall and install package again

I FINALLY GOT THE SOLUTION

Hello guys I finally found a solution to this error.

So the problem is first caused because temporary files could not be created in the /bin or .pub-Cache

To fix this go to their respective folders which are in the flutter folder and the first start with the bin folder and change its security options to allow for ALL APPLICATION PACKAGES and then the .pub-Cache the same .

Run flutter doctor and if you get a license error just follow the steps given by flutter doctor and you are good to go.

This happens to be an active issue and the flutter team is currently working on it. The problem is specific to the Windows operating system. You can try the following workarounds for now:

1) Make sure your installation does not reside in any directory which requires special privileges like Program Files. If that's the case, you can try running it as admin for now but you should change your installation directory to a user's data directory as soon as possible (@Günter Zöchbauer has already pointed this out in the comments).

2) Try restarting your machine.

3) Try deleting the .dart_tools folder and also try clearing the cache in flutter/bin/cache

4) Try disabling your antivirus and/or windows defender temporarily (although it's not really possible for people working on corporate machines). This issue could have been caused by an active antivirus locking your files temporarily.
