Shared libraries stripped by F-Droid

[amake]

F-Droid apparently strips shared libraries that are provided as binaries. It looks to me like they want the source included and the libraries to be built at application build time.

This results in failures like this at runtime:

I/flutter ( 2660): fallback to open DynamicLibrary on older devices

I understand that this is arguably an F-Droid problem, but it is something that consumers of this plugin need to know if they want to publish to F-Droid.

Examples of F-Droid apps that are building golang binaries as part of their app recipes:

It would satisfy F-Droid's requirements for flutter-openpgp to build the binaries at app build time, but failing that it seems the expected thing is for app developers to arrange for building any such binary dependencies as part of the F-Droid build phase:

I will post my solution when it's confirmed working.

Here is an F-Droid build configuration that successfully results in a working APK containing flutter-openpgp binaries:

@amake thanks for this. I really appreciate the time you took to implement it. Sorry I couldn’t be of help
