The Android side of flutter uses Gradle (the same as any other android project). If you have an existing android app, you can probably port over most of the same settings from your gradle files.

Instead, use gradle's build-in dependency resolution. You should be able to follow Amazon's android sdk set-up directions. The difference is that you'll have to hook up the calls to the SDK through method channels and write your own interop code.
