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.

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.

EDIT : SOLVED.

Many users were trying to use the aur/flutter package together with aur/dart-sdk-dev. Since that package didn't behave as the extra/dart package. The build failed. If you try out the aur/flutter=3.19.4-18, this should be fixed.

I hope you will now be finally able to enjoy the new Flutter package - hopefully without further major issues. If not, keep posting here or in GitLab, I'll give my best to investigate !

Many user report an error with the Flutter tool trying to figure out the current version.

_TypeError: Null check operator used on a null value

Those of you who are fine with using GitLab, I'd highly appreciate more detailed bug reports in this issue : https://gitlab.com/flutter-archlinux/tool/-/issues/1

@WithTheBraid I keep getting the same error "Null check operator used on a null value". Does anyone know of an alternative to installing flutter while this (broken) package is being fixed?

After installing the new package I am getting this error:

An exception occurred applying plugin request [id: 'dev.flutter.flutter-gradle-plugin']
> Failed to apply plugin 'dev.flutter.flutter-gradle-plugin'.
   > /usr/lib/flutter/bin/internal/engine.version (No such file or directory)

I also cannot find the file anywhere anymore. It used to be there with the old version. Does anyone know what package I am missing or where the file might end up?

Anyone knows why i get this error even though I can search and even build the packages it says are not satisfied? I am using pamac by the way

EDIT: I ended up building it by installing all the dependencies first

Error: Failed to prepare transaction:
could not satisfy dependencies:
- unable to satisfy dependency 'flutter-engine-android' required by flutter-target-android
- unable to satisfy dependency 'flutter-engine-linux=3.19.4' required by flutter-target-linux
- unable to satisfy dependency 'flutter-target-linux=3.19.4' required by flutter
- unable to satisfy dependency 'flutter-target-android=3.19.4' required by flutter

- unable to satisfy dependency 'flutter-target-web=3.19.4' required by flutter

@stelbl The dependencies are sadly due to the way Flutter is concepted. The flow is to install :

1. flutter-common

2. then installer flutter-material-fonts and flutter-sky-engine

3. flutter-engine-common

4. flutter-engine-*, flutter-gradle, flutter-tool

5. flutter-devel, flutter-target-*, flutter-intellij-patch

6. flutter

packages and then to install all remaining packages of the flutter package.

In case you use an aur helper, ensure that one can properly resolve between these subpackages. E.g. yay reaches there, though it's sadly very slow (it keeps repackaging the package dozens of times).

So I just tried to update but I've been getting these no matter what I do (tried both with flutter and aur/flutter);

resolving dependencies...
warning: cannot resolve "flutter-engine-linux=3.19.4", a dependency of "flutter-target-linux"
warning: cannot resolve "flutter-engine-web=3.19.4", a dependency of "flutter-target-web"
:: The following packages cannot be upgraded due to unresolvable dependencies:
      flutter-target-linux  flutter-target-web

:: Do you want to skip the above packages for this upgrade? [y/N] 

What's even weirder is that explicitly trying to install flutter-engine-{web,linux} installs flutter-engine-{linux,web}-google-bin. I guess some dependency declarations of flutter-target-{web,linux} need to be updated?
