TL;DR

Upgrade using aur/yay might take very long and works inefficiently.

Upgrade using aur/paru requires the -d flag.

This is not my fault.

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 without additional flags. Please use paru -Syud (whereas the -d is the relevant flag) to upgrade 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/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.

• flutter-dart-google-bin : The Flutter original Dart SDK - downloaded from Google servers. This is helpful if the extra/dart package is not available in the right version on your distro or remix.

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 !

Apart from all the package conflict problems that come up, the basic problem is that every time the Flutter package is updated, a series of conflicts between different things starts again, from messages about kernel errors, package conflicts etc. There was no exit, in my opinion, so I finally decided to remove the package and solved all of my problems by installing Flutter from Snap, following this guide:

https://ubuntu.com/blog/getting-started-with-flutter-on-ubuntu

Now, EVERYTHING works like a charme

if it still doesn't work, you can install it from the get started page of flutter : https://docs.flutter.dev/get-started/install/linux/android?tab=download

fwiw I think this is a very positive change to this package and am happy to see it. Thanks for your work!

@WithTheBraid Can you pin a comment explaining how to install flutter so that it works and what do when there are updates to flutter or dart? Finding the magic combination of versions between this PKGBUILD, flutter-artifacts-google-bin, and dart-sdk-dev is not enjoyable.

I noticed that for me too. I just downloaded the source from the flutter webpage. You just extract it and set the path to the flutter/bin directory you put it in, and it just works. You don't even need dart. I guess I won't use this package until it's fixed.

@KI9N

after use dart-sdk-dev, now it report

Unexpected Kernel SDK Version 415669e260 (expected d946408c55).

@abend: yeah this has to be rethought, or someone needs to take over... having flutter as a broken package is definitely not sustainable.. :/

The dependency tree is completely broken with that split that was done. All AUR flutter dependencies use the same git url.

It's now working for me. As highlighted below in @KI9N's comment below the culprit is in extra/dart, substituting which with aur/dart-sdk-dev has resolved the dependency conflict for me.

It is rather simple to reproduce this using the following procedure on the CLI.

paru -Rs flutter dart

paru -S dart-sdk-dev

mkdir flutterbuild
cd !$

git clone https://aur.archlinux.org/flutter.git
cd flutter;makepkg -sfC;cd -

git clone https://aur.archlinux.org/flutter-artifacts-google-bin.git
cd flutter-artifacts-google-bin;makepkg -sfC;cd -

sudo pacman -U $(find . -name \*.zst | tr '\n' ' ')

FIX FOR THE ERROR:

Unexpected Kernel Format Version 117 (expected 114)

1. Install the aur/dart-sdk-dev package! (DO NOT USE extra/dart)

2. Rebuild and reinstall aur/flutter
