Receiving the same problems this morning, done some research.

In my case, I directly pulled the project from GIT they provided and then received the usual '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 on
https://flutter.dev/go/android-project-migration to migrate your project.' problem, after amending this bug and add the code, I received the same problem as you posted.

The reason this happens might related to SDK version and their source code from git were in an older version of dart and flutter, after following the steps on https://www.youtube.com/watch?v=nqY2kdEED5w, it dosen't change the default SDK version.

Got a few insights from https://stackoverflow.com/questions/37293082/uses-sdkminsdkversion-15-cannot-be-smaller-than-version-16-declared-in-library.

Solution 1: find build.gradle and change the minSdkVersion along with the targetSdkVersion to a new version, for example: 28 and 30 respectively.

Solution 2: if you could copy all the assets and configuration files from the begining in a new flutter apps you created yourself instead of cloning from GIT, this won't be a problem.

Feel free for to follow up if you have more questions.

I was getting the same error. In my case, I created an app new from the android studio and just added the assets. But the way I was referencing from the yaml file was wrong and was getting this error.

Below is wrong

assets:
  - assets

Below is right

assets:
  - assets/
