Arch Linux User Repository

This package is deprecated in favor of aur/flutter which now contains all required artifacts on its own. This PKGBUILD will be kept as is in order to ensure seamless builds of old Flutter version in future.

I tried to install this package after the rewrite and it simply doesn't work. I get the same error as @alephaleph. No, I didn't use any AUR helper. I downloaded the repo manually and installed this with makepkg -si along with https://aur.archlinux.org/packages/flutter-engine-common-google-bin installed the same way.

To "fix" this, I simply installed the package from the latest commit before the rewrite, and lo and behold, it works just fine. Link: https://aur.archlinux.org/cgit/aur.git/commit/?h=flutter&id=2942f591ec73f3a8c132cd77a1331507dc581475

splitting the package turned out to be, at least for me, the worst mistake you could make, a source of perennial problems every time Android studio updates its internal plugins or when a new version of flutter appears on the repositories.

Leaving this aside, I'll explain how I solved the dependency problems between the various packages (I use Manjaro):

1. remove flutter and everything related
2. check that you have the aur/dart-dev-sdk package and not extra/dart: with the latter flutter does not compile because it says that the Dart SDK is missing
3. install trizen as pamac frontend

Then, install the packages in this order:

1. trizen -s flutter-devel flutter-tool flutter-common flutter-intellij-patch
2. trizen -s flutter-material-fonts-google-bin flutter-sky-engine-google-bin flutter-engine-common-google-bin
3. trizen -s flutter-engine-android-google-bin flutter-engine-linux-google-bin flutter-engine-web-google-bin
4. trizen -s flutter-gradle-google-bin flutter-target-android flutter-target-linux flutter-target-web

I got the same error when compiling of alephaleph (commented on 2024-04-22 08:14 (CEST))

Unexpected Kernel Format Version 117 (expected 114)

Hi! First of all, thank you for the package and for the pinned comment about the problem with the problem when resolving the dependency chain (this one).

In my case, I use Manjaro and pamac. Removing the package and installing it again using pamac doesn't works:

1. pamac remove flutter
2. pamac build flutter

It returns again the same dependency problems. So I confirm everything was removed, then run yay -S flutter and in the installation wizard:

• I chose flutter-bin for all questions about the two packages that provides the dependency target and flutter-tools package.
• Then I chose "A" to clean all the package before compilation.
• Then I chose "N" to not show any diff, but I imagine this decision doesn't involves any change in the process (sorry, first time using yay!).
• Then, confirms to continue with the installation when notice me about the new package to install: lld-16.0.6-1. Same for unionfs-fuse-3.4.1.
• Then asks me for sudo password.
• Warns me about conflicts between flutter-bin and flutter-common.
• Warns me about a not resolving dependency, flutter-tool=3.19.6, for flutter-devel. Chose "n" to not omit.
• Again warns about flutter-tool, dependency of flutter-devel, and flutter-target-[linux|android|web], dependencies of flutter. Asks me to omit them, I chose "N".
• Finally, the installation breaks...

I leave the process written here in case it is helpful to debug this. If I achieve to install it again, I will update the comment.

Edit: okay, I think I misunderstood the fixed message, I just see this comment. I will try it.

Edit: at least to me, makepkg -sfC and pacman -U doesn't works. With makepkg it builds all the packages to be installed, but then using pacman I was installing one by one in the order they require, but there are missing packages. I will try it in the future, but by the moment I decided to use the installation method provided by the VSCode's extension.

Same issue when flutter run in version 3.19.6

Upon upgrading to flutter 3.19.6, builds are always failing. This is irrespective of the deployment method, in relation to WithTheBraid's pinned comment from 2024-03-28 00:44 (UTC).

Flutter itself built fine with 0 warnings, but Flutter applications currently fail to build with

ERROR: Target kernel_snapshot failed: Exception

Quick internet search points to incompatibility between Flutter SDK and Flutter Engine, but I am not sure as pkgvers seem to be identical.

Also same problem as @CareAgain reported with flutter run, most likely same root cause.

I have the same problem with the last update:

Unhandled exception: Unexpected Kernel Format Version 117 (expected 114)

flutter clean and flutter pub get --> not work
flutter pub cache repair --> not work

Do you have any ideas?

Trying to update to 3.19.6-1 and I get the following whenever I flutter run:
