Current way to differentiate flutter version to use is by creating a symlink in the root project directly.
Unfortunately this symlink uses absolute path, and it does not make sense to commit it into git repo.

A solution that comes to mind is like what nodenv uses. It stores the version to use in .node-version file in the root project. This file contains a version string, and contains no path. So it can be commited to git.

The nodenv package also provides anode executable in ~/.nodenv/shims/node that then calls the requested version node binary.

How about supporting this ? You can do your building for IOS and Android without needing all the android and ios stuff on your laptop. SO you can basically deploy IOS apps WITHOUT needing to hae a mac.

ALso they have an app that you can put on your mobile that will download the build output.

Its basically fastlane and many others reengineered.

I have been using it for 3 months. Its the easiest CI and CD i have found for FLutter.

In nutshell just indicaton which version is configured as global

Thx

Such as the 1.17.0 isn't start with 'v'.

The 'v' is hard-coded into the tool, so I can't use it download them.

For example, I want to save sdk data on a mounted external disk.

In brew you can have multiple version but still point to the same folder. This folder is a symlink to the current version. This way I don't need to set the version of dart everytime in IntelliJ

i see your assuming that a flutter path exists in the env variables.

not everyone has it this way.

why not make it possible to pass in the dir as a variable when this is run ?
that way the developer can pick the folder where they want flutter to be installed.

For example here is my .bash_profile

#git clone -b dev https://github.com/flutter/flutter.git
export FLUTTER_ROOT=$HOME/workspace/flutter/standard/flutter
echoLog "FLUTTER_ROOT (exported)" $FLUTTER_ROOT
export PATH=$PATH:$FLUTTER_ROOT/bin

fvm does not find it:

x-MacBook-Pro:go-flutter apple$ fvm
No Flutter versions installed

When using flutter channel to switch versions from within a cached version. Can cause other project that depend on that SDK not to be aware.

• Update cached version after flutter channel
• When using on another project it should recover the version

Hi @leoafarias,

Thank you so much for making this tool! I am spending a lot of time switching Dart versions and testing for compatibility so this tool will make that much simpler.

Unfortunately, I am unable to instal a flutter version. I've tried fvm install 1.7.8+hotfix.4 but it said it could not find the version. I also tried fvm install v1.7.8+hotfix.4 which didn't work either.

Here's the error log:

Is there a way to set the Dart / Flutter sdk locations in IntelliJ Idea for a specific project? I'm particularly interested in setting this for Flutter / Dart as I have different installed versions for different projects (I'm using fvm).

I know how to set them in the system preferences -> language & framesworks but this sets them for all projects and I'd like to have a specific fvm install for a specific flutter project.

@leoafarias I have installed "Flutter 1.17.0" using fvm (v0.8.3)

I can run my android successfully. But when I try to run it on iOS, it says "Upgrading project.pbxproj" which removes App.framework and Flutter.framwork from Runner/Flutter which causes following error and app gets stuck at launch screen itself

[VERBOSE-2:engine.cc(112)] Engine run configuration was invalid.

I tried to degrade the version from 1.17.4 to 1.12.13+hotfix.5 which runs smoothly on both platforms.

Is there anything related to fvm which I am doing wrong or have not set up correctly.

Plus, when I execute fvm config, it says "No configuration has been set".

FVM is compatible with Flutter Channels, however, if a channel is a tag, and you run "flutter upgrade" it will cause it to bring it to the latest version of the channel, and lose the version.

This happens due to the fact of the way FVM symlinks the versions.

Also, there seems to be a caching issue on IDEs sometimes based on the symlink version. One of the solutions for this is to change the strategy away from symlink that more closely resembles what flutter channel expects.

Describe the bug

Currently the docs assume that the user has Dart installed globally. Should probably add some verbiage to explicitly say that or add instructions for when you're only using the Flutter installed version.

To Reproduce
Steps to reproduce the behavior:

1. Run install commands without having Dart installed globally with .pub-cache added to path.

Expected behavior
Expect the documentation to reflect missing steps and account for users who only have the Dart version shipped with Flutter installed.

Describe the bug
fvm list does not recognize the installed flutter version

I think this has to do with some env variables or PATH etc.

To Reproduce
Steps to reproduce the behavior:

1. Install flutter using the standard way mentioned on flutter.dev
2. install fvm following the installation guide
3. run fvm list
4. Returns ==> No SDKs have been installed yet.

I would like to change the global fvm directory location from /Users/sven/fvm to /Users/sven/.fvm. However this does not seem to be possible at the moment, right? Maybe fvm can honor an environment variable like FVM_HOME if set?

I purpose fvm create be followed by selector from installed versions of flutter and based on selected one, it should proxy to flutter create of that version. After flutter create, flutter use or in future flutter alias also executed to hook up with fvm.

Thx

One of cool things about fvm is the ability to lock flutter version. But for me locking dart version in project might as useful. I know it might be allot of work. But @leoafarias what do you think. Does this idea make sense?

List available flutter versions of download, including current versions for channels

I've been getting the following error while trying to change SDK to the local one.

fvm install 1.18.0-12.0.pre no response

I think we should recursively look up the parent directory and find the most recent fvm file.
To support nested projects, you can just put fvm in the root directory.

After you've installed fvm cli and all works fine, you can add in you Android Studio project the feature to build directly with the Flutter version that you want follow this simple step:

1. copy the path of fvm symbolic link in your root project directory.
   example {fvm-path}/versions/beta/bin/flutter
2. in the Android Studio menù open Languages & Frameworks -> Flutter or search for Flutter and change Flutter SDK path to the previous path
3. Apply the changes

You now can Run and Debug with the selected versions of Flutter.

Thanks for this version management system, is wonderful!

I want to create an debug build like that:

fvm flutter build apk --debug

but it throws the following error:

⚠️  Could not find an option named "debug".
Unhandled exception:
Could not find an option named "debug".

With npm you can pass arguments like that to the subcommand:

npm test -- --coverage

but it doesn't work with fvm:

fvm flutter build apk -- --debug 

Any ideas?

Hey @leoafarias
I was about to write something like this to speed up doing flutter projects. Thanks for this.

Check this out too !
https://github.com/go-flutter-desktop/go-flutter/blob/master/example/simpleDemo/engineDownloader.go

It allows downloading the Flutter dependencies for Desktop.

How about also incorporating this ?

If I run
flutter run --verbose -d chrome --web-hostname localhost --web-port 7357

so that my chrome instance is running on a specific port (needed for google sign in) it works fine.

If I enter the same but with fvm on the start I just get errors that the options aren't defined.
Would it be possible to add support for these?

Thank you very much for your project. Hope to show the progress bar and download speed when using the 'fvm install' command, otherwise I don't know how long it will take me to download it.

Hey @leoafarias

Dart implementation allow project specific version, which is cool, but to be honest, I still want global flutter version like go version. Right now I am just soft linking to /usr/local/bin, will be cool if you allow global linking and switch will cli as before.

Thx

I found an old post that says you can install fvm using npm, yarn, or go, but the npm version is behind the current pub version.

Is it still possible to do this?

Describe the bug

In 0.x version a symlink was created when calling fvm use stable and it was possible to call all flutter commands by just starting them with ./fvm e.g. ./fvm doctor. Now it doesn't work anymore.

To Reproduce
Steps to reproduce the behavior:

1. Go to some Flutter project directory in command line
2. Execute fvm use stable
3. Execute ./fvm doctor
4. See error zsh: no such file or directory: ./fvm

Expected behavior
I would expect to flutter doctor for stable be executed. Or there should be some description how to use fvm in console.

I did something wrong? Or it's really a bug?

Desktop (please complete the following information):

• OS: macOS Mojave (v10.14.6)
• FVM Version [e.g. 0.8.3]

Describe the bug
Hi, I'm trying to proxy to the flutter pub command to execute build_runner. It doesn't seem to be possible.

To Reproduce
Run flutter pub run build_runner build --delete-conflicting-outputs

Expected behavior
build_runner is executed. Instead, I see an error that --delete-conflicting-outputs is not an option.

Desktop (please complete the following information):

• MacOS 10.15.5
• FVM Version 0.7.1

Why are they gone?
Has there a specific issue?

Maybe we can also incorporate the Flutter Desktop. This uses the Flutter Embedder.
It means you can run your Flutter code on Desktop as well as Mobiles.

look at this:
https://github.com/go-flutter-desktop/go-flutter/blob/master/example/simpleDemo/engineDownloader.go

Notice how they use symlink for MacOS, but not for Windows or linux.

How about if we incorporate this into fvm ?

The engineDownloader checks the current flutter installed and downloads the right version of the flutter embedder, which is nice.
