I see this warning in all kinds of places. I just checked out package:rfw for example, ran flutter pub get in the wasm example (which doesn't have an Android anything), and it told me "This app is using a deprecated version of the Android embedding." and created a java plugin registrant.

Hixie · 2022-12-14T20:27:20Z

Subsequently running flutter run -d linux in that directory also showed me the message.

Same problem here:
flutter create --template=package --project-name=foo .
flutter test
gives:

Plain dart package works fine (dart create -t package foo)

It's true for me too. I encountered the same problem when I tried to create a package for my new project. I would like to use a package for the packages directory within my app project

Does this mean I need to edit every package I create? My goal was to use package-based separation

When creating a package, using flutter create -t package test --no-pub avoids the android embedding bug

When creating a package, using flutter create -t package test --no-pub avoids the android embedding bug

True, but when you add android, the warning is there

LeonManolo · 2023-03-22T10:33:48Z

What is the difference between "dart create --template=package-simple " and "flutter create --template=package "? The one starting with flutter also creates android, ios, web folders but that shouldnt be the case if Im not wrong:
https://docs.flutter.dev/development/packages-and-plugins/developing-packages#step-1-create-the-package

NebulaFox · 2023-03-22T13:59:49Z

The embedding warning turned into an error when trying to run tests. In my specific case, if you include device_info_plus which requires android embedding v2, the tests will not run.

I also wondered if I should be using plugin instead of package.

Just an update: since my tests don't actually use device_info_plus as they are just unit tests I can run flutter test --no-pub to get round the problem.

AlexLomm · 2023-03-24T07:51:41Z

Should the advice be followed as suggested by the warning message?

Has there been any update on this?

Any ideas on how to solve this issue? I am currently using Android Studio to create a package, but it will constantly warn me about the outdated Android Embedding.

I used fvm to be on 3.3.10 when creating a package.

flutter create --template=package is creating lots of crap it shouldn't for some reason.

I compared it to one of my previously created packages and just deleted the android, ios, linux, macos and windows folders + the .idea folder, the .iml file and the dartpad folder from the .dart_tool folder.

Worked for me, hope it works for you too

same issue when using the flutter create --template=package demo. I cant run the unit test on my package , deleting android, folder solves it but not sure if that's the correct way to fix it. Hope flutter can release some hot fix on it

marcov-dart · 2023-04-19T14:35:41Z

I am pretty sure it shouldn't have any of the platform folders in the first place. Only plugin packages have those. And when you create a plugin package with flutter create --template=plugin demo it doesn't get those folders until you add platform support with flutter create --template=plugin --platforms android,ios .
And the plugin template by the way doesn't have the deprecated android embedding problem.

`package` template should not create platform folders. This happen cause by default all platforms are supported and tools didn't distinguish between package and other template, which makes all platforms are true for below code, https://github.com/flutter/flutter/blob/d186792c00f61149916f685e2975300342f64749/packages/flutter_tools/lib/src/project.dart#L374-L380 fixes: #119844 which make #116320 makes invalid. As for why tools created deprecated `Android Embedding`, `appManifestFile` does not exist for `package` template, which make below code to trigger, https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/project.dart#L768-L770 This does not happen with `module` and `plugin` as it have specific condition check for them. I try to reproduce it with `app` template but didn't succeed

Thanks @andrewkolos.

Since I already started a package with a lot of work using the old template (created by flutter 3.7.1), how should I proceed? create a new template and migrate all the files?

#125292 was only merged into the master branch, so it is not yet available in the stable or beta branches.

In the meantime, it should be sufficient to delete the unnecessary platform folders (including android) in your project.
