I upgraded my software yesterday to MacOS Ventura. Today when I opened my project so I can work on it, I cannot get to build the app because I get this error: The current Flutter SDK version is 0.0.0-unknown.
Running "flutter pub get" in elfi_menu...
The current Flutter SDK version is 0.0.0-unknown.
Because country_icons 2.0.2 requires Flutter SDK version >=0.1.4 and no versions of country_icons match >2.0.2 <3.0.0, country_icons ^2.0.2 is forbidden.
So, because elfi_menu depends on country_icons ^2.0.2, version solving failed.
pub get failed (1; So, because elfi_menu depends on country_icons ^2.0.2, version solving failed.)
Exited (1)
I have tried to reinstall flutter, I get the same error, I also tried opening a new project, same error. I also looked it up on the internet but I saw pretty old similar issues, they are fixing it on Windows and it is not the same here on mac from what I've seen.
Does anyone have any ideas why this happened and how to fix it?
Thank you very much in advance
EDIT
Above the output I have written in the code, this is a line that appeared:
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
I searched for the solve on the internet and this like solves the problem, written in the terminal:
xcode-select --install
This fixed it for me:
Open Xcode
Go to Preferences
Go to Locations
Use the "Command Line Tools" dropdown to select the available Command Line Tools
Mine was empty and I chose the single available option: "Xcode 14.0.1 (...)"
Restart console, everything should be working
To solve the problem, I have written this in the terminal:
xcode-select --install

I'm having a problem accepting the Android Licenses. I've looked for well over a month for a solve and haven't found one yet. My username on my mac contains the word (Deleted) with a space before it and I'm wondering if that's causing any problems.
I run $ flutter doctor and get this result:
I run $ flutter doctor --android-licenses
And I get this error:
Error: Could not find or load main class (Deleted).Library.Android.sdk.cmdline-tools.latest
I have all the SDK tools installed and updated to the latest. What I have installed is pictured below:
I have Java 8 installed and running, as well. Not getting any errors with Java.
Could use another pair of eyes to see what I'm doing wrong.
Here is my flutter doctor -v output:
First set android sdk path by flutter config --android-sdk <path-to-your-android-sdk-path>
and run flutter doctor --android-licenses again
I have started with the setup of flutter updated version and am a total beginner in this platform. This is the error I have been getting. Could you please help me?
You have to install Android SDK Command-line Tools (in SDK Manager).
After Installing, accept the android licensces (in CMD)
flutter doctor --android-licenses
Either install Android Studio to get the required dependecies or download an android sdkmanager and check its path (path/to/sdkmanager should be the path to that).
To avoid any problems for beginners, I would just install Android Studio here, set it up until it installs the android sdk, then switch to Flutter: that was the only way to fix this since some time ago if I remember correctly
Please first run this command
flutter doctor --android-licenses
then follow this link : Android/Sdk is missing a Tools folder, meaing no sdkmanager, meaning "Android license status unknown" error
I've been trying to solve this error since one day.
First I got this error
Exception: Android sdkmanager tool not found (/ usr / lib / android-sdk / tools / bin / sdkmanager).
Try re-installing or updating your Android SDK,
visit https://flutter.io/setup/#android-setup for detailed instructions.
Here is a Screenshot
I tried to solve this error but couldn't solve it and I deleted Android Studio completely (sdk, gradle, .android ... etc). I reinstalled and flutter I got this error when I wrote doctor. New errors Screenshot
C:\Users\Fatihh>flutter doctor --android-licenses
Warning: File C:\Users\Fatihh\.android\repositories.cfg could not be loaded.
4 of 7 SDK package licenses not accepted. 100% Computing updates...
Review licenses that have not been accepted (y/N)?
C:\Users\Fatihh>
Finally I made the decision to write here. I need help.
Android studio version:4.1.1
OS :Win 10
Flutter SDK :1.22.5
Android SDK:30.3
First, open Android Studio and install Flutter and Dart plugins on it.
Then run the command flutter doctor --android-licenses
Finally, clean your project, make sure packages are installed and run it
flutter clean
flutter pub get
flutter run

First Make sure you have a working internet connection and if this issue still exists then, this error may be because the dart sdk may have not been properly downloaded.
The simplest solution is to delete the cache folder located in
flutter/bin(location where flutter is installed) and then Run flutter doctor
I fix that by:
Ctrl+C to stop infinite error loop.
Kill the Dart process in Windows Task Manager.
Delete the cache folder located in flutter/bin directory.
Run in command line flutter pub cache repair.
After that I run flutter doctor and get predictable results:
e:\tools>flutter doctor

I found my antivirus blocks pub upgrade,I had same issue while hitting flutter doctor, I turned off my antivirus and tried to run "flutter doctor" again, and worked well!
windows:
simplest and easiest way is download the latest version flutter sdk. replace manually current folder by pasting downloaded flutter folder instead of the current folder
in c drive. always choose replace and paste.
after finishing that check with flutter doctor. my issue solved
Solved this issue when Run the CMD as administrative.
This issue will come in protected network as well as due to anti-virus. Even I was facing the same. I downloaded latest stable version manually from the following link, which doesn't required any update process and it works for now..
Download Link For Flutter in Zip format
I updated the flutter SDK via git pull, then the flutter doctor command works.
Just delete the cache folder in flutter/bin and run flutter doctor again!!
Just Deactivate your antivirus and run it again. It would work fine. I had the same issue before.
I deactivated my antivirus for some time and executed flutter doctor command once again in cmd and got fruitful results after hours of patience.
One more thing to note, you should ensure that path of dart-sdk folder should be added to the path in user variables.
It seems it is not being able to "unzip" the downloaded Dart file because it misses 7-zip uncompressor.
I installed it and it worked! It will deal with .7z files.
I hope it works for other people too!!
I had the same problem and it was solved.
Steps:
Download Dart and Filters SDK then Decompress these files and move them to this directory.
C: \
Define the variables in path:
Delete cache directory in flutter/bin
Then run flutter doctor
Make sure you downloaded the windows powershell i use windows 8 it wasn't installed by default , when i downloaded it it worked for me.
Check your flutter bin path in environment variable(User Variables). If not go to Under User variables check if there is an entry called Path:in that add this flutter/bin path.
Strangly when I kill the dart process in Windows Task Manager it is working. But sometimes even when dart process is running update working.
I had to turn off the Android Emulator. It was running for me...
I got the same error and was not able to get rid of it. So I deleted the flutter and instead of cloning it I downloaded the zip from the flutter website and extracted it. Now it works just fine.
Manually downloading the SDK from flutter website fixed the issue.
Still dont know why this problem occured tho.
If you are using Avast (or possibly some other anti virus too) on Mac and have recently updated the OS to Big Sur then follow the below steps to fix this issue
Open Avast and in the Web Shield area disable the "Scan secure connection".
Run flutter config --no-analytics and then run pub upgrade.
This should probably fix the issue.
You can also refer to below threads in Github for more details about the cause
https://github.com/flutter/flutter/issues/40515
https://github.com/flutter/flutter/issues/68999
In my case, the error resolve after adding below folder into exclude option in anti virus
Flutter SDK location
D:\Android\flutter_windows\flutter\*.
Flutter Local Pub folder
C:\Users\hitesh\AppData\Local\Pub
You get the error --
"Pub failed to delete entry because it was in use by another process.
This may be caused by a virus scanner or having a file
in the directory open in another application.
Error (1): Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (1 tries left)" even if you are in one of the flutter directories from Windows explorer. Close the window and try running Flutter doctor. This will resolve.
If anyone faces this problem on macOS with AdGuard installed. Try this:
Go AdGuard Preferences -> Network -> Automatically filter applications -> Select Mode... and change mode to Automatic Proxy.
Pub failed to delete entry because it was in use by another process.
This may be caused by a virus scanner or having a file
in the directory open in another application.
Error (1): Unable to 'pub upgrade' flutter tool. Retrying in five seconds... (9 tries left)
Tried switch to Dev channel and got stuck with "Unable to pub upgrade". Did everything and nothing worked.
This is what I did:
Renamed the Flutter SDK folder
Download the latest Flutter SDK
Extract to the same location of previous renamed SDK
Flutter channel Dev
Flutter upgrade
And everything back to normal.
Source of Problem
It might be possible that you don't have enough free disk space. That's what caused my problems to begin with.
Solution
In my case,
First I had to clean up space to remove any unused files.
Then I had to overwrite the flutter SDK folder due to corruption. The SDK can be found here.
I had the same issue with my MacBook M1. I tried deleting and running flutter pub cache repair But It didn't work for me.
Then I ran the command softwareupdate --install-rosetta and accepted the software licences & agreement (After installing XCode). Now the command flutter works fine. :)
Tried all of the above without success. The search order in the PATH system variable turned out to be the problem:
it was:
G:\My Drive\Compilers\flutter\bin;
G:\My Drive\Compilers\flutter\bin\flutter;
G:\My Drive\Compilers\flutter\bin\flutter.bat;
G:\My Drive\Compilers\flutter\bin\dart.exe;
G:\My Drive\Compilers\flutter\bin\dart;
G:\My Drive\Compilers\flutter\bin\dart.bat;
changed it to:
G:\My Drive\Compilers\flutter\bin\flutter
G:\My Drive\Compilers\flutter\bin\flutter.bat
G:\My Drive\Compilers\flutter\bin\dart
G:\My Drive\Compilers\flutter\bin\dart.bat
that fixed it
Mac auto iCloud upload might be causing the error
If you are using Mac and if your Desktop files are being uploaded to iCloud automatically, sometimes iCloud uploads the "bin" file or the "cache" file inside the flutter file. I've just downloaded the file onto desktop (right click the file -> "Download Now") and it downloaded the file, it ran as usual. (Automatic upload can be turned off from system preferences if youn are getting this error frequently like I was).
For my case, i was using ubuntu, and after reading the above comments, i have come to a resolution that the above error comes as a result of permissions being blocked, accessing cmd with admin access levels solves the problem, e.g on linux run sudo flutter doctor and the problem will be solved.
This error occured to me when i tried upgrading my flutter so it needed admin rights to be upgraded nothing much
