[Unclear documentation] libflutter_engine.so: cannot open shared object file: No such file or directory
I've followed your guideline from README step by step and app was built just fine, but when I run it with flutter-pi --release I get:
/home/user/flutter_assets/libflutter_engine.so: cannot open shared object file: No such file or directory. Trying to open libflutter_engine.so.release...
Could you please clarify in docs where I can get libflutter_engine.so.release and where to put it?
Kind regards

That's not an error. There's multiple locations where the flutter engine can be located and this is just the first one that was tried. Does the app run fine after that?

The flutter engine will be installed in the first step of the dependencies section

nope :(

I have dependencies already installed and flutter-pi without --release works just fine

Sure

flutter: The Dart VM service is listening on http://127.0.0.1:45385/yl0jcYDmzP4=/
Your issue seems to be related to https://pub.dev/packages/package_info_plus have look at the method channel defined here : https://github.com/fluttercommunity/plus_plugins/blob/main/packages/package_info_plus/package_info_plus_platform_interface/lib/method_channel_package_info.dart The package_info_plus package is not supported on flutter-pi at the moment , consider writing your own native code or custom platform interface , otherwise you can just not use it.
Thank you. The question is why it throws exception in "release" mode instead of returning empty string like in "development" mode?
Somehow in debug mode it recognizes it runs on linux and sets PackageInfoPlatform.instance to linux, but in release mode it doesn't and it defaults to MethodChannelPackageInfo and you'll get the MissingPluginException.
Probably the dart plugin registrant isn't running in release mode somehow, though not sure why. But there's some other unsupported plugins that show similar behaviour: https://github.com/ardera/flutter-pi/issues/222
(If you do flutter build linux and then run flutter build bundle --target=.dart_tool/flutter_build/generated_main.dart, it'll probably run without the exception again)
@ardera and about:
Probably the dart plugin registrant isn't running in release mode somehow
is it a bug in Flutter itself?
Have you tried handling the exception ? (In case it is causing the application to crash)
I want to use the package_info plugin, so handling the exception will not make me a difference ;)
@ardera and about:

Not really, officially flutter only supports: android, ios, the official linux desktop embedder, the official windows desktop embedder, macos and so on. Flutter-pi is not officially supported. So it's surprising the dart plugin registrant is running in debug mode even. (But again, even if it ran in release mode, that doesn't change the fact that the plugin is not supported)
Though that doesn't stop you from writing your own package_info -like functionality of course
