I'm getting this warning after using "Flutter Doctor" command after the installation of Dart using brew tap dart-lang/dart on MacOS Big Sur
Flutter (Channel stable, 3.7.0, on macOS 11.7.2 20G1020 darwin-x64,
locale
en-GB)
! Warning: dart on your path resolves to
/usr/local/Cellar/dart/2.19.1/libexec/bin/dart, which is not inside your
current Flutter SDK checkout at /Users/puneet/development/flutter.
Consider adding /Users/puneet/development/flutter/bin to the front of your
path.
Can you anyone tell me how can i resolve this issue?
I'm trying avoid this warning and run a code on android studio developed on flutter framework.
I resolve this warning by just uninstalling the dart sdk using this command -
brew uninstall dart
Since dart sdk already comes with flutter installation, you need not to install it seperately.
Here is how I solve this problem
My dart path on environmental variable was look like (Both user and system variable)
C:\src\dart-sdk\bin
Now I change it to
C:\src\dart-sdk\bin\dart.exe
and the problem resolved.
The Flutter framework also contains Dart. So, if you already installed Dart separately on your OS, remove Dart and its Path from your system. You should have only one Path that is: /Users/puneet/development/flutter/bin
SOLVED
when you update your flutter to the latest version this warning comes in your flutter doctor output:-
for solving this just go and open .zshrc and after that check your flutter bin path is like this:-
change your path into this:-
and then run flutter doctor again... PROBLEM SOLVED ☺️
I can build flutter project .
but I did catch warning by flutter doctor
I want fix .

Just remove old dart from homebrew
brew remove dart
Important note from flutter documentation:
The Flutter SDK contains the dart command alongside the flutter command so that you can more easily run Dart command-line programs. Downloading the Flutter SDK also downloads the compatible version of Dart, but if you’ve downloaded the Dart SDK separately, make sure that the Flutter version of dart is first in your path, as the two versions might not be compatible.
The previous text means that flutter SDK has Dart SDK inside it, So you don't need to download dart separately.
To solve this proplem :
Delete the dart SDK that you download separately.
Go to the environment variables then select the Path from the user variables.
Change C:\src\dart-sdk\bin to C:\src\flutter\bin\dart
I solved it by adding the dart/ directory inside flutter/bin directory.
Hope this might help! :D
I fixed it by deleting the separate "dart-sdk" folder that I downloaded, and keeping the downloads from the flutter which has everything in it already.
Mine was in C \ tools \ dart-sdk
You may also have to change\delete the env path that had dart-sdk separate, and only keep the flutter\bin path. I have both flutter\bin & flutter\bin\dart. Not sure if both are needed but mine worked.
I was facing the same issue after upgraded to 3.7.x. In my case, I didn't set anything about Flutter in my .zshrc, I just created a symbolic link instead like this:
sudo ln -sfn /Users/lin/flutter/bin/flutter /usr/local/bin/flutter
So, when I am facing this issue, I think it would probably be working for Dart as well. Here is how I fixed it:
(1) Verify Dart:
which dart
It prompted dart not found
(2) Create a symbolic link for Dart:
sudo ln -sfn /Users/lin/flutter/bin/dart /usr/local/bin/dart
(3) Verify Dart again:
which dart
It prompts: /usr/local/bin/dart
dart --version
It prompts Dart SDK version: 2.19.2 (stable) (Tue Feb 7 18:37:17 2023 +0000) on "macos_x64"
(4) At this point, it will be working if you type:
flutter doctor -v
Good day Guys, i'm new on flutter & I wan set up flutter and the android SDK(without using android studio) on my device but when i run flutter doctor --android-licenses command i get this error after running the command
(/home/olaneat/android/Sdk/tools/bin/sdkmanager).
Try re-installing or updating your Android SDK,
visit https://flutter.dev/docs/get-started/install/linux#android-setup for
detailed instructions.
this is how i configured my path
ANDROID_HOME="$PATH:/home/olaneat/android/Sdk"
export PATH="$PATH:/home/olaneat/android/Sdk/platform-tools"
export JAVA_HOME="/usr/lib/jvm/java-11-openjdk-amd64"
export PATH="$JAVA_HOME/bin:$ANDROID_HOME/cmdline-tools/tools/bin:$ANDROID_HOME/platform-tools:SPATH"
and i have my SDK already installed
can anyone help out?
Update cmdline-tools direcotry
Try changing the path name cmdline-tools/tools to cmdline-tools/latest. I was facing the same problem and found that the directory patern has been updated.
I want to build a flutter web app, so I enter 'webdev build' command and after the operation finishes, I open the 'index.html' file located in build directory and it's just a white screen.
I tried it on a fresh project and the problem persists.
There's no problem during developing.
Here's my flutter doctor output:

For me seemed to have been a problem with antivirus and running flutter run -d chrome --release solved my problem.
You need to run webdev serve command, it'll provide an address like localhost:8080 or 127.0.0.1:8080. I've attached a screenshot after running webdev serve for one of my Flutter Web Project. It says Serving web on http://127.0.0.1:8080 So you need to open that URL in Browser.
This answer was written when flutter-web was a separate project and webdev was the way to go for running your app.
Now you can use flutter run -d chrome to run it for Web.
You have to upload your files to the server and put them inside the root folder.
If you want to put them in other folder, you have to edit the "index.html" file to tell hem the folder.
For example:
If you upload your files to "test" folder, you have to edit this line of "index.html":
<base href="/">
To
<base href="/test/">
I had the same issue. I was in stable channel and doing below solve the issue:
flutter clean
flutter pub get
flutter pub cache repair
I hope solve your problem.
I had the same issue.I used inspect code on chrome and checked console section.So there was error not allowed to load local resource and a Path to some file was like this:
import 'file:///C:/Users/../someFile.dart';
And by changing path to
import 'package:.../someFile.dart'
white screen gone and problem solved.
I didn't pay attention to this part from the documentation,"run the application using a static HTTP server.". I was just opening the index.html not using it is server.
For me I was in master channel and doing below solve the issue:
flutter channel dev
flutter upgrade
flutter run -d chrome
just run flutter config --enable-web in your command line and close your editor and after run the app again
I had the same issue. I was in master channel and doing below solve the issue:
flutter clean
flutter pub get
flutter pub cache repair
I had the same problem with my app running as a blank page in Chrome. I've fixed it by re-creating a project with flutter create .:
move your lib directory and pubspec.yml file to a safe place.
then, delete the rest of the files and directories in your project directory.
run flutter create ..
move back in those files from step 1.
form me was to replace
<base href="$FLUTTER_BASE_HREF">
to
<base href="">
in index.html file

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
