Hi I'm looking to export the signature and send it to the server in a json string. What is the best method to achieve this?

I was thinking.. Uint8List signature = await _signatureController.toPngBytes(); String signature64 = base64Encode(signature);

But this is giving me an error Unhandled Exception: type '_InternalLinkedHashMap<String, String>' is not a subtype of type 'String'

Sorry this was the wrong place to post this and the error was my fault. Completely unrelated issue.
