Arch Linux User Repository

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 !

@nahuelmorata Can you elaborate ? When does this error occur ? What did you try to do ?

Btw. to downgrade the package, just go into the directory you have the AUR package cloned into (or where your AUR helper stores it in) and check by git log the revision to checkout. The just use git checkout REF to checkout a previous version and execute your regular makepkg with your preferred options.

How can I downgrade the version of flutter? I get this error when i use the command "flutter downgrade x.x.x"

Switching to flutter channel 'stable'... Switching channels failed fatal: not a git repository (or any of the directories above): .git.

@WithTheBraid Sorry for the incomplete answer, I didn't realize. So to change the version of Flutter do I have to go to the folder where the AUR package is, change the version using it and do the makepkg again?

There is a bug in the flutter.sh script. In line 12 it uses string replacement, which is a bashism. The shebang should specify bash and not POSIX shell.

@juaji Sad manjaro still ships dart 3.0.7. Anyway, I now patched the flutter package to also compile with dart-sdk-dev (though I highly suggest the arch extra/dart package). This should now also work on manjaro without further workarounds.

Greetings, as discussed here the workaround for the error "Null check operator used on a null value" consists of create a symbolic link from /opt/dart-sdk-dev to /opt/dart-dev. This (I assume) taking into account if: 1. dart is installed using dart-sdk-dev 2. The operating system is Manjaro and not ArchLinux (as is my case) since the "extra" repo of Manjaro has dart in a version lower than the required one (3.0.7, see), but the "extra" repo of ArchLinux has dart in the required version for this package (>=3.3.2, see). By doing this (that is, the symbolic link) the error disappears, however it was a way out of an error and finding others that have already been discussed regarding dependencies. I suggest installing flutter using flutterup, it seems to do the work, it has not taken me more than 5 minutes what I have been trying to do for three days.

@silikeite yay does loop but it's not infinite. It just seems like it. It builds it around 10-12 times and takes about half an hour but it does work. paru manages to do it properly.

PKGBUILD structure is causing yay to not be able to properly build this package - yay just loops and repeatedly tries to build flutter over and over again.

EDIT: Saw the comment earlier regarding yay taking a long time to build. For now I'll switch back to using Google's official way of installing flutter until this package's build process settles down.

@Papitz Thanks for the comment, looks like I forgot to include the engine stamp into the Android target. I will publish a fix in a moment.
