I have built an image with the following setup added to my local.conf

DISTRO_FEATURES_append = " opengl wayland"
IMAGE_INSTALL_append = " flutter-gallery flutter-wayland-client flutter-wayland"

How do I run the flutter-gallery App ? I couldn't find a lead

the follwoing isn't working:

# flutter_wayland /usr/share/flutter-gallery/sony/data/flutter_assets/
LOG: /usr/src/debug/flutter-wayland/git-r0/git/src/main.cc:65: Arg: /usr/share/flutter-gallery/sony/data/flutter_assets/
terminate called after throwing an instance of 'std::runtime_error'
Bus error

flutter_wayland was my initial wayland POC, and I haven't looked at it in quite some time. I'll make some updates and add example steps in the readme.

I did look at the readme but it's not helpful:

# flutter_wayland 
   <Invalid Arguments>   
Flutter Wayland Embedder

========================
Usage: `flutter_wayland <asset_path> <flutter_flags>`


This utility runs an instance of a Flutter application and renders using
Wayland core protocols.

The Flutter tools can be obtained at https://flutter.io/

app_path:      This either points to asset bundle path, or
               an Ahead Of Time (AOT) shared library (.so).

asset_path:    The Flutter application code needs to be snapshotted using
               the Flutter tools and the assets packaged in the appropriate
               location. This can be done for any Flutter application by
               running `flutter build bundle` while in the directory of a
               valid Flutter project. This should package all the code and
               assets in the "build/flutter_assets" directory. Specify this
               directory as the first argument to this utility.

flutter_flags: Typically empty. These extra flags are passed directly to the
               Flutter engine. To see all supported flags, run
               `flutter_tester --help` using the test binary included in the
               Flutter tools.

and as readme suggest it does not work the follwing way:

# flutter_wayland /usr/share/flutter-gallery/sony/data/flutter_assets/
LOG: /usr/src/debug/flutter-wayland/git-r0/git/src/main.cc:65: Arg: /usr/share/flutter-gallery/sony/data/flutter_assets/
terminate called after throwing an instance of 'std::runtime_error'
Bus error

so my question is how to bringup flutter using this layer at all ?!

I must no use wayland.

You wrote in previous issue that flutter-drm-eglstream-backend is working only for NVIDIA ( doesn't build anyway).

I spent quite some times trying to figure out how it work but it's really very confusing.

Thanks anyway

Eglstream is for NVIDIA, drm-gbm is for Mesa. If you are not building an NVIDIA target image, you can't use it. You then use flutter-drm-gbm-backend. Standard embedded Linux graphics stuff.

Yes without prior experience embedded Flutter has a steep learning curve, and can/will be frustrating. I know as I learned it from scratch without any help.

Another bit of advice which will decrease frustration is to "bringup" the selected embedder on Linux desktop using an IDE such as CLion. This make understanding and resolving issues much faster. Once that all works, then move to the target. After that the only remaining items may be around install path and image symlink issues.

My flutter_wayland repo has been updated. I am able to run the Gallery app on Fedora 24 with FLUTTER_CHANNEL="dev". I also updated the flutter-wayland recipe to this commit.

Keep in mind when switching channels or handling channel rolls (weekly) you need to clear things via:

bitbake flutter-engine -c do_clean
bitbake flutter-sdk-native -c do_clean
bitbake flutter-gallery -c do_clean
bitbake flutter-gallery
bitbake flutter-drm-gbm-backend

Unless you're running pipeline builds that don't persist state.

@jwinarske : ticket was closed too early :-)

bitbake flutter-drm-gbm-backend is not building at all with FLUTTER_CHANNEL="master"

So in summary this layer seems to be working only for NVIDIA :-(

built the with new flutter-wayland that was recently commited and used as suggested FLUTTER_CHANNEL="dev"

I have the same error as before:

# /usr/bin/flutter_wayland /usr/share/flutter-gallery/sony/data/flutter_assets/
LOG: /usr/src/debug/flutter-wayland/git-r0/git/src/main.cc:65: Arg: /usr/share/flutter-gallery/sony/data/flutter_assets/
terminate called after throwing an instance of 'std::runtime_error'
Bus error

Note: I'm always building from scratch

I closed it, as I addressed the filed issue. See the flutter_wayland repo for example.

Stringing issues together doesn't help others.

Given gallery currently builds with "dev", "master" is not something one normally targets unless you're generating PRs for the engine. "Beta" is recommended for flutter app development. At one point "master" was required for the gallery app, which is not always the case.

The Sony recipes are currently autorev, as they are still in flux. If you want stability either find a commit you want to lock to and patch, try flutter-pi (drm-gbm), or write your own. All of the current public embedders are not a complete commercial solution. Mostly a best effort, or POC (flutter_wayland). I implemented/own the embedder Toyota is using, and it is far more sophisticated than any of these. This layer is a starting point for many.

What SoC are you targeting?
What OS and version is your container running?

There are many companies using this layer including my own.
