they put Dart in the Flutter archive for some reason

Yes, the reason is that breaking changes to the Dart SDK are landed with the corresponding fixes to the Flutter SDK. Also, you cannot "remove it" without significantly altering the Flutter tooling. The Flutter CLI tool ensures that the pinned version of the Dart SDK is present in its binary cache.

If you want to use a version of Flutter without depending on Flutter's pinned version of the Dart SDK, you would need to maintain a separate fork of the Flutter SDK, that tracks the breaking changes of the Arch Dart package, and has an updated Flutter tool that doesn't assume it controls the Dart installation.

I maintain the latest built package at:

https://github.com/frealgagu/archlinux.flutter/releases/

@ricardosimoes i also got the same error and did the same to fix it. ^_^

@ricardosimoes I also encountered the same issue on Arch, did the same thing you did.

Got error: failed to commit transaction (conflicting files) flutter: /opt/flutter/.git/FETCH_HEAD exists in filesystem on MANJARO, but I ran sudo mv /opt/flutter/.git/FETCH_HEAD /opt/flutter/.git/FETCH_HEAD.bak and then it built fine

Solution to mkdir: cannot create directory ‘/opt/flutter/bin/cache’: Permission denied
You need to run the command to add your user to the group.
Run gpasswd -a <user> flutterusers

Not sure if this is an issue but flutter doctor started giving me this error:

fatal: unsafe repository ('/opt/flutter' is owned by someone else) To add an exception for this directory, call:

git config --global --add safe.directory /opt/flutter

Which is true because /opt/flutter is owned by root.

The solution mentioned in the error works though.

Running flutter doctor i get this error: Flutter failed to check for directory existence at "/root/.pub-cache/hosted/pub.dartlang.org/_fe_analyzer_shared-31.0.0/lib/". Please ensure that the SDK and/or project is installed in a location that has read/write permissions for the current user. Try running: sudo chown -R $(whoami) /root/.pub-cache/hosted/pub.dartlang.org/_fe_analyzer_shared-31.0.0

Any suggestion?

Hello

When I try to do this as a user (deps for another package):

flutter config --enable-web
mkdir: cannot create directory ‘/opt/flutter/bin/cache’: Permission denied

is it possible to change the cache directory somewhere else ?

btw, 2.8.1 already. And I wanna show you my update function without AUR pkg.

u() {
  # ...
  asdf update
  asdf plugin update --all
  asdf install flutter latest
  asdf global flutter latest
  export DART_SDK=$(asdf where flutter)/bin/cache/dart-sdk
  # ...
}

Also you can upgrade flutter over flutter (if you install it from flutter.dev) - flutter upgrade and even flutter downgrade, also you can change channel for upgrade/downgrade (example flutter channel {stable|beta|dev|master}; flutter upgrade) https://docs.flutter.dev/development/tools/sdk/upgrading

thank you for the 2.8 update @frealgagu

@romjan1412 a little busy with zero-day log4j vulnerability. But it's now up to date (2.8.0).

By the way, you can use asdf-vm with flutter plugin or https://fvm.app to install latest flutter without delays

just a heads up 2.8 is released now

why this is not updated yet?

/opt/flutter/bin/internal/shared.sh: line 229: /opt/flutter/bin/cache/dart-sdk/bin/dart: No such file or directory

i'm peacefully using flutter! but after few days of break this error comes up!

Yes it blows my mind, they put Dart in the Flutter archive for some reason. I think we can safely remove it from there and use the system Dart

Cannot we use dart package instead of downloaded dark sdk from flutter?

@Rodancoci One should note that a restart of the computer is needed to make the change take effect.

@Rodancoci I compile my packages in a clean chroot and those packages are not needed to be specified in the PKGBUILD. Glu is a dependency of this package and it requires ninja and clang (check). It's strange that you didn't have those packages already installed.

Figured it out. clang and ninja should be added as makedeps.

The proper way to avoid the /opt/flutter/bin/cache permission error is to add the current user to the flutterusers group created by the flutter package. The flutter directory is owned by the root user and the flutterusers group.

usermod -aG flutterusers <user>

I'm getting a new error now, though:

CMake Error: CMake was unable to find a build program corresponding to "Ninja".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.

I got permission errors when running flutter:

$ flutter                      
mkdir: cannot create directory '/opt/flutter/bin/cache': Permission denied

I "fixed" it by running sudo chmod a+rw -R /opt/flutter

I opened a PR to update this: https://github.com/frealgagu/archlinux.flutter/pull/9

This package was flagged out of date on the 4th of May for not releasing the 2.0.6 update; however, the 2.0.6 Flutter release was a hotfix for a bug on macOS and it doesn't concern GNU/Linux.

Form Flutter's official Github page:

2.0.6 (April 16, 2021)

This is a hotfix release that addresses a single issue:

• Issue #81326 - macOS binaries not codesigned There are no code changes to this release, but binary artifacts for macOS were re-built and codesigned.

.git is required by the CLI tool. The others aren't required, but if you mutate the checkout then the flutter upgrade command won't work.

Are the .git/, .github/, .idea/ folders really required? They are massive (over 135MiB) and seems to have no use at all. Shouldn't the PKGBUILD leave those out of the install process?

I had the same problem as hossamdash and following his solution fixed it.

I had the same problem as hossamdash and following his solution fixed it.

flutter-dev is now orphaned, didn't you think about taking it?

so i have installed this package but was facing two issues: Although i had the dart package installed on my system -which this package depends on-, both installing this package for the first time and each flutter doctor -v command results in the redownload of the dark-sdk which is inside /opt/flutter/bin/cache disregarding both the existing dark-sdk in the cache and the standalone dart package installed on my system. to solve this i did two things, i uninstalled the standalone dart sdk and then added a line to the build files of this package right after the chmod -R g+w /opt/flutter line. this line is chmod g+s /opt/flutter makes any files created within the /opt/flutter path inherit the group flutterusers which stops flutter doctor from redownloading the dart-sdk.

I think that flutter is designed to be self-upgraded. Hence in the end I decided to clone flutter repo instead of using AUR.

Getting failed to commit transaction error.

Using the --overwrite /opt/flutter/packages/flutter_tools/.packages option solves the issue, but the question is, is it fine to overwrite?

same

resolved with

$ mv /opt/flutter/packages/flutter_tools/.packages /opt/flutter/packages/flutter_tools/.packages.old

But I experience a LOT of

warning: directory permissions differ on $
filesystem: 775  package: 755

I experienced basic packages missing on my projects (incorrect URI), idk if it's related but I was able to correct that with flutter pub/packages get and a lot of restart/reloads

I get the followeing:

error: failed to commit transaction (conflicting files) flutter: /opt/flutter/packages/flutter_tools/.packages exists in filesystem Errors occurred, no packages were upgraded.

I maintain the latest built package at:

https://github.com/frealgagu/archlinux.flutter/releases/

(solved) I cannot get to update flutter. having conflict error. Is it because I did >flutter upgrade ?

EDIT: OK just delete the directory and a clean install solves the issue.

yay -S flutter-group-pacman-hook
chgrp -R flutterusers /opt/flutter
chmod g+w /opt/flutter
sudo usermod -a -G flutterusers $USER

Is not enough to execute flutter as non-root, someone getted it to work here?

flutter 
        create $PROJECT
        doctor

@solstice, you can use this pacman hook to achieve the same thing:

https://aur.archlinux.org/packages/flutter-group-pacman-hook/

You forgot to add a post_upgrade() in .install:

chgrp -R flutterusers /opt/flutter
chmod g+w /opt/flutter

Otherwise, an upgrade will cause problem

If you're getting issues with installing dependencies like the following:

-> Could not find all required packages:
    lib32-libva (Wanted by: flutter -> lib32-libglvnd-git -> lib32-mesa-aco-git)
    lib32-libxext (Wanted by: flutter -> lib32-libglvnd-git)
    lib32-libxext (Wanted by: flutter -> lib32-libglvnd-git -> lib32-mesa-aco-git -> lib32-libdrm-git -> lib32-cairo-git)
...
...
...

I've made a PR to the maintainer with a fix here:

https://github.com/frealgagu/archlinux.flutter/pull/2

@btimofeev: flutter needs to be run as root, or you can use a hook like mine (flutter-group-pacman-hook) to declare a group having the permissions to use it (it defaults to fultterusers group as it is the example in the PKGBUILD)

flutter doctor ~/mkdir: cannot create directory '/opt/flutter/bin/cache': Permission denied

@hack.augusto my trick is flutter-group-pacman-hook package, but it will throw some warning when upgrading flutter. The package adds a pacman hook that will apply the "right" rights on /opt/flutter. You can define whatever group you want it applied to, but defaults to flutterusers.

git and bash are required, and should be moved to regular dependencies (and unzip added). And I think dart should be removed altogether, as flutter vends its own (custom) version of the dart sdk.

@hack.augusto A package must not use local users in building, the app itself should use a local config for its usage, so it's not something that should be changed in the PKGBUILD. Other packages like npm, go or python are installed as root and to install specific adds, they need to be installed as root (or even be installed using other AUR package). Flutter is more recent that those other packages but I think that this is the way to install adds in the future.

Thanks for the PKGBUILD!

I'm not found of the idea of running flutter as root, maybe the package could create the flutterusers group by default?

These are the lines I added to my local package:

chown -R :flutterusers "${pkgdir}/opt/${pkgname}"
chmod -R g+w  "${pkgdir}/opt/${pkgname}"

Yes, we should add unzip as a dependency, it's listed as one of the system requirements https://flutter.dev/docs/get-started/install/linux

Looks like flutter is requiring unzip to download packages (It throwed me errors about this when automatically installing dart for example). I don't know if we should add it to the dependencies...

opt/flutter/bin/internal/update_dart_sdk.sh: ligne 93: unzip : command not found

@Ionaowna, did you install all four Android SDK packages?

Hm, I've installed android-sdk, yet flutter doctor doesn't seem to like it:

Doctor summary (to see all details, run flutter doctor -v):
[✓] Flutter (Channel stable, v1.17.1, on Linux, locale en_US.utf8)
[✗] Android toolchain - develop for Android devices
    ✗ ANDROID_HOME = /opt/android-sdk
      but Android SDK not found at this location.

1.17.0 looks straightforward to build, however i had to:

sudo pacman --overwrite /opt/flutter/\* -U flutter-1.17.0-1-x86_64.pkg.tar.xz

I needed to add the multilib repo so all the lib32 things would work. https://wiki.archlinux.org/index.php/Official_repositories#multilib

For those still having issues. Go to /var/tmp/pamac-build-[username]/ , delete the flutter folder and try again. Fixed it for me.

ERROR: One or more files did not pass the validity check! Failed to build flutter.

I have visited github flutter issue page,and i don't get what i have to do for install flutter via AUR.

Yup, 3f241c6237078338a0568d1e161f5d4b6d47ea3af377c9522d17223a9bb94c96 looks to be the good checksum now...

@kronaemmanuel I bet that's because of https://github.com/flutter/flutter/issues/55082. Because of an infra change I made, the stable package got regenerated today, and I wouldn't be surprised if the checksum of the archive changed.

I'm getting this error. Any ideas on what I can try?

==> Validating source files with sha256sums...
    flutter-1.12.13+hotfix.9.tar.xz ... FAILED

sudo setfacl -m u:YOURUSERNAME:rwx -R /opt/flutter/ can also solve some permission issues before the flutter fix https://github.com/flutter/flutter/issues/44526.

Writing here for if anyone faces the same issue, in my case everything worked except for the hotreload feature, so i had to do flutter version 1.16.3. Otherwise hotreload and hotrestart buttons were gray.

@TheAifam5 unfortunately, at this time, maintaining the .git directory is required for the flutter sdk to work. For example, running flutter doctor uses git to check the version. There is an outstanding github issue to fix this, to better support installation from package managers: https://github.com/flutter/flutter/issues/44526.

If you are REALLY concerned about the disk space, you can make your git repo a shallow clone, via:

git pull --depth 1
git gc --prune=all

That for me got my .git directory from 157mb to 95mb ¯_(ツ)_/

Why lib32-libglvnd is required?

@rockypra Thank you for the clarification. I wonder if that is needed, even the package sticks to the specific version, and AUR provides also other versions like beta and dev.

Flutter SDK works that way, unfortunately. They use git for version management even for the user local snapshot. If you're managing Flutter SDK on your own, you can change which channel of release you want to follow with flutter channel Channel switching is basically fetching from their github repo, doing the branch switching, and updates the local snapshot. That's why when you try to change the channel or doing an upgrade you can see a lot of git related process like pulling from the git repository and/or branch switching.

No way that this package contains .git.... just WHYYYY... is SO BLOATED

didn't have time to dig in to why this might be a bad idea so someone feel free to correct me, but after upgrading I needed to chown the entire /opt/flutter/bin/cache folder to get going again, since it was all owned by the root:root group.

edit: cache updates frequently so this is just an (Extremely) temporary solution.

I've been working on this package to remove the permission errors. I've put up the changes at https://github.com/mattyclarkson/aur-flutter. See the commit message for the various improvements.

Mainly, it allows the package to work without any permission errors and a vastly reduced package and install size.

if updating this package after manually upgrading flutter it fails because the files already exist.

warning: directory permissions differ on /opt/flutter/
filesystem: 775  package: 755

This happens for any installation, upgrading.

please add flutter binary to path

This fixed the permission issues for me:

sudo chmod a+rw /opt/flutter/bin/cache/lockfile /opt/flutter/version

Those issues are all permission issues, as all files in the package are owned by root. You can check this in the flutter logs.

@d-sha How do you fix it manually? @g4rrucho this package is under heavy development and it's still in beta phase. If anyone have ideas of how to fix the issues and how could I improve this package please let me know

Hi, When installed flutter crashes with permission errors: /opt/flutter/bin/cache/lockfile' (OS Error: Permission denied, errno = 13) /opt/flutter/version' (OS Error: Permission denied, errno = 13)

I fixed this locally but i dont know what the best way to fix the package. Thanks.

Flutter constantly crashes. Anyone has any idea how to fix it?

here is my PKGBUILD for flutter. it will install in /opt/flutter, add ENVIRONMENT VARIABLES in /etc/profile.d and just use "flutter upgrade" to upgrade
