which folder has to be delete for clean uninstall FVM package/Flutter Version Management ?
First apply the official uninstallation steps in the following page in the official docs for the package, select the platform from the taps above and check the Uninstall section.
If you want to also delete all the configs of FVM along with all the installed SDKs, you can type the following in the Terminal/Command Prompt:
fvm config
You will see an output similar to the following:
FVM Settings:
Located at C:\Users\moaze\fvm\.settings
cachePath: D:\Development\Flutter-SDK\versions
skipSetup: false
gitCache: false
You can see to paths in the output, one for the FVM Settings and one for the SDKs which is cachePath, you can delete both folders.

I am trying to use fvm on Windows.
Because my projects use mixed of languages, I need to change the version globally.
The problem is that it keeps asking me to change the flutter path.
At first,
So, I moved flutter path down to the bottom of fvm\default\bin.
Here is how I setup the path.
Now, if I change global flutter version again, the path is changed as the version of fvm, not the default... which is not in the path at all.
If it is just the message, I can ignore, but when I try to open up my project and try flutter --version the global version is not changed.
Can anybody guess what is the problem?
I did install with flutter pub global activate fvm.
I tried deactivate and activate again, removed reset the path in various ways, but keep getting same issue.
Another thing is I am keep getting Can't load Kernel binary: Invalid SDK hash message. I just assume this is kind of related to the first issue, but not of it.
Thanks.
I guess I solved this issue.
First of all, I had flutter installed version 1.22.6 at the beginning. and installed fvm with flutter pub global activate fvm. Then, the fvm version 1.3.7 installed. If I try to install flutter version 3.x.x, it fails with message like Internal Error: Could not infer Flutter Version 3.x.x or fvm version 1.3.7 doesn't support ~~~ something like that. So, I upgraded the actual flutter installed to the latest version, and also upgraded fvm to the latest version. Then, it never go back to 1.22.6 globally with the fvm.
So, I reinstalled the flutter version 1.22.6, complete uninstall fvm by flutter pub global deactivate fvm and also deleting fvm folder.(if you don't delete the folder and reinstall, it will install the same version of fvm you previously installed) And reinstall with flutter pub global activate fvm. Then, it will then install fvm 1.3.7 version. With this version of fvm, I couldn't install 3.0.2, but could install stable
but using different commands for this fvm 1.3.7 version.... like fvm use stable --global... you can find some commands here
it was because of the actual flutter version installed and fvm version I guess.... Please comment below if I was wrong.
Lets say I am starting a new dart project. I have a few packages on pub.dev I know that I want to use, and I want to use the most recent version of these packages.
Right now, I open my browser and go to pub.dev and find each package, then check the Versions or Installing tab to find out what the latest version is so I can put that in my pubspec.yaml. Then I can run pub get
Using npm, you can run npm install <package> and npm will automatically fetch the latest version of the package and add it to package.json
Is there a pub command, syntax for pubspec.yaml, or something else that will make pub resolve the latest version of a package and use it in my project, without having to manually look up the latest version?
Normally in Flutter, the packages which you want to use need to be added to pubspec.yaml and run pub get. But there are also some IDE plugins like npm.
For example, Pubspec Assist is using on Visual Studio, you can add or update your dependencies without going pub.dev. But you have to know which packages do you want to use at least for a time.
https://marketplace.visualstudio.com/items?itemName=jeroen-meijer.pubspec-assist
Simply enter the following command in the terminal
flutter pub add provider
Of course, where it says provider, put the package you want to install.
The package with the latest version is automatically added to your pubspec.yaml.
Otherwise you can always do what #jamesdlin said and leave the version field empty.
I am trying to install the flutter version manager to switch the flutter version among the different flutter projects.
I use the command to install the fvm - pub global activate fvm
but when I run the command on the terminal - fvm help
There is an error -bash: fvm: command not found
How to fix it ?
Your .pub-cache binaries are not yet added to your PATH variable, used by your terminal. Add path with the following command:
export PATH="$PATH:$HOME/.pub-cache/bin"
This is the location where fvm is installed. So by exporting this path to your PATH variable you should be able to get fvm working from anywhere in your terminal.
If you installed fvm using pub and you already have it in your path but you are still getting the error, follow these steps:
run dart pub cache repair // You may get an error: Failed to precompile fvm:main:. Just ignore that for now.
run dart pub global activate fvm
you can do a
flutter clean
then when its done, run
dart pub global activate fvm
when it's done it should work now, close the current bash terminal and open a new one
You must add the path to the fvm executable to the $PATH environment variable. After running "pub global activate fvm" you should have seen a warning with instructions on how to fix it. You can watch this: https://youtu.be/R6vKde1vIGQ
That will get you up and running.
if use windows 10 or later add system properties -> Environment Variables -> Path -> %USERPROFILE%\AppData\Local\Pub\Cache\bin
First confirm if fvm.bat is executing successfully, you should have the folder already in environment variable PATH(%USERPROFILE%\AppData\Local\Pub\Cache\bin). If it is then for fvm to run in bash, instead of fvm.bat, you need to create a shortcut, a file named fvm with no extension, the containing folder should also exist in PATH variable, the file contains location to fvm.bat and ends with a whitespace and S*.
I just added the the fvm package to switch the flutter channel from stable to master without downloading sdk components every time when switching flutter channels.
I have followed the step written in readme.md for switching the channel.
I have set the following path in my environment variables.
D:\Program_Files\FlutterSDK\SDK\flutter\bin;
D:\Program_Files\FlutterSDK\SDK\dart-sdk\bin;
C:\Users\User\AppData\Roaming\Pub\Cache\bin;
Now, i have opened my first project in which i want to use "flutter SDK's master channel". But, whenever i try to use the command "fvm use master". It's not working.
It is giving me an error like,
'fvm' is not recognized as an internal or external command,
So, can anyone suggest a solution?
Thanks.
try :
pub global run fvm:main
pub global run fvm:main use VERSION
Hi adding in your path:
%LOCALAPPDATA%\Pub\Cache\bin
More info:

In my case fvm commands did not work on Windows even tho I checked everything. It gave missing fvm.exe file and other errors. If you also stuck there you can use this way. Only way I managed to get it work is to use longer commands like these:
flutter pub global run fvm:main list
Seems like all fvm commands:
config Set configuration for FVM
flutter Proxies Flutter Commands
install Installs Flutter SDK Version
list Lists installed Flutter SDK Version
releases Lists Flutter SDK releases.
remove Removes Flutter SDK Version
use Which Flutter SDK Version you would like to use
version Prints the currently-installed version of FVM
Works like this, you just need to add the fvm command to the ending of this - flutter pub global run fvm:main. So add any of them like this form:
flutter pub global run fvm:main releases
flutter pub global run fvm:main install 2.2.0
flutter pub global run fvm:main use 2.2.0
are you add "C:\flutter\bin\cache\dart-sdk\bin" to path?
if you in windows you should run your text editor as administrator as following
In my case Error Message was
Usage Error: Flutter version null is not installed
To fix this:
I have activated FVM by pub global activate fvm;
Printed installed fvm list by fvm list, it should give result as the image below:
Selected which Flutter SDK version to use by running fvm use 1.22.0 (in my case 1.22.0, it may differ according to your desired version) command, It will download SDK if it is not installed yet;
Now you can check is flutter running in your project by running flutter;
Also, you can check if the Flutter SDK version set by calling again fvm list.
The tick means, that version is running in your project.
I am not able to generate the documentation of the code by using the dartdoc tool located at C:\flutter\bin\cache\dart-sdk\bin. This is what I do:
Go to the project dir dir C:\Users\alber\Documents\progetto_fomet\fomet_app\lib
Call the command dartdoc
It works because in C:\Users\alber\Documents\progetto_fomet\fomet_app\lib\doc\api I see the documentation but it doe NOT include the documentation of my code!
The tool generates the doc of dart like here
but it does NOT generate the doc of my app in flutter
In red you see the source of my app that is not being doc-generated in doc\api. What to do?
I am on Windows 10
I was struggling with this a lot.
Solved by the following steps using the PowerShell:
Installing CHOCOLATEY from https://chocolatey.org/install#individual
Activating dartdoc using flutter pub global activate dartdoc
Activating dhttpd using flutter pub global activate dhttpd
Generating the documentation dartdoc on the project folder
Viewing the generated files using dhttpd --path doc/api
Alternatively on macOS you can use Homebrew to install the dartdoc and dhttpd
