Google Play Store & Flutter: couldn't find "libflutter.so" on Google Pixel 2 (virtual)

Question

I'm encountering an issue when publishing my application on the store, and I don't want to go through multiple releases to try all the solutions I've found on Stack Overflow.

Here's my error:

couldn't find "libflutter.so"
  at java.lang.Runtime.loadLibrary0 (Runtime.java:1012)
  at java.lang.System.loadLibrary (System.java:1669)

From what I understand by reading the Stack Overflow posts, it seems like I should add the following to make it work: https://stackoverflow.com/a/76292482/6401457

We also can read comments in this posts, 3 peoples have the same problem with the same device

I would like to understand why, especially after reading this: https://docs.flutter.dev/deployment/android#build-an-app-bundle

I generate my releases using Codemagic, and I don't want to use credits for my tests.

Do you have a solution?

Thank you.
