Arch Linux User Repository

Note to the lovers of AUR helpers : It looks like dependency resolution is a complex topic. Despite all package relations being properly declared in the Flutter packages, most AUR helpers seem to have trouble resolving the dependency chain between the package bases aur/flutter and aur/flutter-artifacts-google-bin. This is not my fault and I cannot do anything about it.

It looks like the initial installation works fine using aur/paru. Sadly aur/paru does not reach at building updates for the package.

On the other hand aur/yay properly reaches at both installing and updating this package, even though it builds the package 15 times (!!!) again and again.

If you use aur/paru, consider to simply execute pacman -R flutter && pacman -Rns flutter to clean up the previous installation of both package bases.

• https://github.com/Jguer/yay/issues/2413
• https://github.com/Morganamilo/paru/issues/1173

If you build both package bases using makepkg -sfC and later on install all build outputs using pacman -U, both the installation and the updates work like a charm.

I'm very sorry for the inconvenience, but sadly there's nothing I can do about this.

Huge update to the Flutter AUR package :

The previous implementation basically did a user installation of Flutter - downloaded the custom Dart SDK, CI artifacts from Chromium CI and had to be kept in user R/W access in order to have the Flutter Cache Manager working.

These times are now over - a clean and (almost) completely rewritten PKGBUILD which now uses clean dependency declarations, system Dart and Gradle and for sure no more user R/W installation directory.

This AUR entry is now a split package. Installing aur/flutter will still bundle the entire toolchain you knew from before. The other way round, if you don't need everything - e.g. when depending on Flutter as a build dependency in another package, you can choose to only depend on what you need.

The following split packages are available :

• flutter : meta package containing all other split packages

• flutter-common : the common files for Flutter needed for all use cases

• flutter-devel : your option of choice as a developer - ships the Flutter tool and all required templates to e.g. create a new project

• flutter-tool : The pure Flutter tool. Use as depends to build your package.

• flutter-target-linux : The Flutter Linux build files. Use as depends to build your package.

• flutter-target-web : The Flutter web build files. Use as depends to build web apps (e.g. fluffychat-web does this).

• flutter-target-android : The Flutter Android build files. Use if you want to develop Android apps.

• flutter-gradle : The Flutter Gradle wrapper. Populated from system Gradle.

• flutter-intellij-patch : a tiny patch to make the IntelliJ Flutter plugin work with the new package.

• flutter-material-fonts-google-bin : Mandatory fonts package, planned to have a system-installed drop-in replacement soon.

• flutter-engine-common-google-bin : Shared part of the Flutter engine - downloaded from Google servers.

• flutter-sky-engine-google-bin : Flutter sky engine - downloaded from Google servers.

• flutter-engine-linux-google-bin : Linux part of the Flutter engine - downloaded from Google servers.

• flutter-engine-web-google-bin : Web part of the Flutter engine - downloaded from Google servers.

• flutter-engine-android-google-bin : Android part of the Flutter engine - downloaded from Google servers.

• flutter-gradle-google-bin : The Flutter Gradle wrapper - downloaded from Google servers.

Stay tuned for non google-bin versions of the engine, they are in coming !

Since almost everything is written from scratch and heavy patches are applied to use the system packages as dependencies, there might still be bugs occurring. Please report them otherwise I can't fix them !

getting an error: ERROR: JAVA_HOME is not set and no 'java' command could be found in your PATH.

I tried installing stable dart-sdk 3.3.2 on Manjaro using my own PKGBUILD, since the extra/dart package is still in 3.0.7 and dart-sdk-dev from aur uses a different sdk path. Now the error became:

Unhandled exception:
Crash when compiling package:mypackage/main.dart:
Unexpected Kernel SDK Version c09cb46304 (expected bc4150a9a2).

EDIT: I installed extra/dart straight from ArchLinux repo to solve the issue

I got past the "Your Flutter SDK download may be corrupt" message on Manjaro by creating a symlink from /opt/dart-sdk-dev to /opt/dart-sdk.

But now I'm getting a "Unexpected Kernel Format Version 114 (expected 116)" error when trying to run a new test project.

I met the same issue as @StrontiumK9:

Your Flutter SDK download may be corrupt or missing permissions to run. Try re-downloading the Flutter SDK into a directory that has read/write permissions for the
current user.

Same of StrontiumK9 for me. flutter doctor doesn't see any issue on my installation but flutter doesn't even create a new project from terminal, printing that error. Obviously, I got to my user r/w permissions for flutter at /usr/lib/flutter

I just installed 3.19.5-7 with Yay and didn't see any of the reported issues. But I can't run flutter once it has been installed. flutter pub upgrade in my project just complains: "Your Flutter SDK download may be corrupt or missing permissions to run. Try re-downloading the Flutter SDK into a directory that has read/write permissions for the current user."

Is there some post install work I need to do to get it to work?

@ajje Yeah, really sad. I wished I could resolve the problem. Yay btw. isn't in an infinite loop, bu "only" builds the package 15 times - if you are very patient, yay can hence install it.

About paru, I already consider writing a patch to the upstream running pacman interactively - because the build process works way faster using paru.

Alternatively, I'm working on pre-built packages for those who don't wanna manually build them, the progress can be found on the GitLab mirror of this repo, at https://gitlab.com/flutter-archlinux/tool/-/merge_requests/1 .

@WithTheBraid Thank you for your detailed explanation and your patience. Yes, now yay asks if you want to remove the old flutter package, but it still doesn't work for me because I get stuck in an infinite loop trying to build the package. That's why I tried paru, but as you correctly point out, it runs pacman non-interactively.

I see now that some users has suggested uninstalling Flutter manually then doing a clean build with paru. I'll try that. Thanks again for all that you are doing for us lazy users of AUR helpers.

@ajje This is intended. Both yay and paru are sadly not able to first build all packages and install them at once (as pacman -U or pacman -S would do). This is not my fault.

I hence added the conflicts list removing the previous installation in order to make the update work. Using yay, this works. You simply have to accept yay removes the stated packages. paru sadly does not allow that since it tries to run pacman non interactively (I don't get why tho).

Again, these are bugs of AUR helper - it should not be the task of AUR package maintainers to do nothing but workarounding issues of the helpers failing at dependency resolution.

Feel free to open a ticket in paru asking to fix that - as people already did with yay.

I've tried installing with both yay, and now paru but I get conflicting dependencies:
