 ## Dart APIs
 The plugin includes a core API that maps native libsodium functions 1:1 to Dart equivalents. The core API is available in the class [`Sodium`](https://github.com/firstfloorsoftware/flutter_sodium/blob/master/lib/flutter_sodium.dart). Dart naming conventions are used for core API function names. A native libsodium function such as `crypto_pwhash_str`, is available in flutter as `Sodium.cryptoPwhashStr`.

-## Known issues
-- Previous incarnations of flutter_sodium used platform channels for native interop. The latest version has been rewritten to take full advantage of Dart FFI. FFI offers fast native interop and is the obvious choice for flutter_sodium. One minor problem, FFI is still in beta and its API may change. This may affect flutter_sodium.
