I see this warning in all kinds of places. I just checked out
package:rfwfor example, ranflutter pub getin 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 commentedon Dec 14, 2022
Subsequently running
flutter run -d linuxin that directory also showed me the message.Anas35 commentedon Dec 20, 2022
Creating a new packages on windows on latest channel

Same command without running

Plain dart package works fine (
dart create -t package foo)4e6anenk0 commentedon Mar 9, 2023
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
packagesdirectory within my app projectflutter doctor -v
After running the command:
flutter create --template=package testoutput
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-pubavoids the android embedding bugBishop19 commentedon Mar 17, 2023
True, but when you add android, the warning is there
Paolo-N commentedon Mar 19, 2023
LeonManolo commentedon Mar 22, 2023
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:

HeliumEnd commentedon Mar 22, 2023
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
plugininstead ofpackage.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-pubto get round the problem.3 remaining items

Has there been any update on this?
lihenggui commentedon Apr 12, 2023
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 I am currently using Android Studio to create a package, but it will constantly warn me about the outdated Android Embedding.
tamas-p commentedon Apr 14, 2023
I used fvm to be on 3.3.10 when creating a package.
marcov-dart commentedon Apr 15, 2023
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
rddewan commentedon Apr 19, 2023
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 itmarcov-dart commentedon Apr 19, 2023
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.
fix package template create platform folders (#125292)
andrewkolos commentedon Apr 29, 2023
Closing as fixed by #125292
arthurgiani commentedon May 1, 2023
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?
andrewkolos commentedon May 1, 2023
#125292 was only merged into the master branch, so it is not yet available in the
stableorbetabranches.In the meantime, it should be sufficient to delete the unnecessary platform folders (including
android) in your project.github-actions commentedon May 15, 2023
