VS Code-'dart' is not recognized as an internal or external command, operable program or batch file - dart

Question

I am trying to install flutter and run the basic flutter example on visual studio code . I used flutter doctor in the command line and installed all the missing requirements , now i try to run a basic program in flutter ,but in visual studio code output i get the following error
[Running] dart "c:\fluttercode\mobile_test1\lib\main.dart"
'dart' is not recognized as an internal or external command,
operable program or batch file.
[Done] exited with code=1 in 64.965 seconds
I could find only one question similar to this in stack overflow ,
Visual Studio Code: dart not found
they told to change environment variables ,i added the environment variables (however the name of the environment variables was not mentioned in the answer )
I checked the dart site in case they mentioned it ,but i couldn't find anything related to the name of the environment variable
This is what i got from dart site
Windows:
In Windows, setting your PATH and environment variables can be done by opening Control Panel and typing “Environment” and then clicking the “Edit the system environment variables” option. You’ll be presented with a list of environment variables including PATH where you can edit or add new ones.
Note: You should reboot your computer after making changes to PATH to ensure all processes (including explorer) are updated.
So i just did a guess and added an environment variable with the name FLUTTER_ROOT(cause i remember reading somewhere in one of the settings in VS Code for dart ,this name was used) and pointed it to my flutter bin directory
I restarted my PC and opened vs code and changed in VS Settings >user settings>dart and flutter>Dart:Env and updated my path
{
"files.autoSave": "afterDelay",
"dart.flutterSdkPath": "C:\\src\\flutter\\bin"
}
But i get the same error
this is how my flutter bin folder looks like
Environment variables in PATH after installing Dart

Answer 1

You don't have to install the dart SDK if you already have the flutter SDK installed. When you specify the path of flutter, VSCode only recognizes the flutter commands and not the dart commands. What you should do is change the system environment variables (type env in the windows search bar) and add the dart sdk inside the PATH variable. The dart sdk is usually found inside /bin/cache/dart/bin. This worked for me, so give it a try

Answer 2

Try to add the flutter\bin sdk path and also the windows\system32 path to the user variables and/or system variables.

Answer 3

I had the same problem. Here is how I resolved it.
Download and extract dart sdk (I used the stable release)
https://v1-dartlang-org.firebaseapp.com/install/archive
add the dart sdk bin folder to your path
after you have added it to your path run
flutter pub global activate webdev
now i can run
webdev serve
without error.

Answer 4

I'm using windows so I used choco install dart-sdk -<version> to install dart through the powershell in admin mode. That got rid of my error

Answer 5

Installing flutter is not enough. You need to install the dart sdk.
Pre-req: Make sure you have Chocolatey installed on your machine.
Run "choco install dart-sdk" from an elevated prompt.
Restart vscode.
That did it for me.

Answer 6

I went to the dart website and searched for the dart sdk.
i then chose the option to install dart using setup wizard.
After running the executable file on my laptop it took some time to download all the files but once the setup was complete the error no longer occurred and i was able to run the code successfully.
