Fidelius for android application

We are implementing the PHR app in flutter for Android and iOS users. We are using the fidelius for encryption/Decryption for value in HIP implementation but the same package might not supported in Android/iOS. So please provide some other method or step by step process of the encryption of value in android.

We have found the fidelius example its used the CLI, so we can not used in android.
