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.

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:

Unhandled exception:

kso: yes. We're all getting shenanigans with this package (I've already seen the "layer.error" error when trying to install it). It goes worse and worse with each new release patch. What worked for me was the steps mentionned by the maintainer:

In all cases, building the two pkgbase repos using makepkg -s[fC] and a manual installation of all output packages using pacman -U works.

Hi the build was working before (back in February 2024) but now I get this error:

==> Starting prepare()...
==> ERROR: A failure occurred in prepare().
    Aborting...
 -> Failed to install layer, rolling up to next layer.error:error making: flutter - exit status 4

Is anyone else getting this error? Does anyone know what is the full name of the "layer" library mentioned in the error?

@WithTheBraid I just got to see your comment in my emails. Sorry for no response.

Apparently, the underlying issue regarding that error wasn't because of the AUR package itself but because I had arch4edu repo added on my install. They forgot to update dependencies for flutter-target-* at the time, causing them to fail to install.

I had that repo added for not having to spend much bandwidth for proprietary packages like google-chrome-stable, but I found out that it's a no-go after this incident.

I absolutely refuse to use Chaotic AUR for prebuilt packages as I build linux-nitrous from its source with USE_MPERFORMANCE=1, which is a flag to enable mtune flag for the detected CPU throughout the kernel. This flag isn't in use on generic repos like CAUR to make it work globally on any system the prebuilt packages are installed on which means performance drawbacks, which kinda defeats the purpose of that kernel for modern hardware.

I apologize for the confusion, just wanted to clear that up.

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
