Your Flutter application is created using an older version of the Android embedding.

Receiving this warning:

Warning
──────────────────────────────────────────────────────────────────────────────
Your Flutter application is created using an older version of the Android
embedding. It's being deprecated in favor of Android embedding v2. Follow the
steps at

https://flutter.dev/go/android-project-migration

to migrate your project.

Have tried to follow the (complex) steps at the referred url, as well as creating a new project and copying source across. Endless trouble, no good result yet.

If anybody has any tips to get this codelab working, I'd appreciate your input.

It looks like we need to update the codelab based on this migration guide: https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects

We will take a look - thanks for the report!

I have a change for this ready, it should be merged early next week.

Note that the app and the codelab continues to function as normal - this message is just an advisory warning. The functionality of the app should not be impacted.

@zacjordaan Did you notice any change in behaviour or did the app not work for you?

Unfortunately the app did not work for me. Beyond the advisory warning, I found issues such as this:

After that, running .\gradlew build --stacktrace didn't provide any additional useful information that I could see.

I'll watch out for your change next week and perhaps try again, thank you.

@zacjordaan I had the same error, you have to change flutter_svg: in pubspec.yaml to ^0.18.1 and then run flutter pub get. This will fix the error. I check for compatibility and make a pull request.
