Which snippet are you referring to?
I tried the snippet in the main README of the "kms" project (2. "use") here:
https://pub.dev/packages/kms
More specifically this was the snippet I used, just to test a signature of a 3-bytes sequence, with Ed22519:
// ...
final kms = flutterKms();
final document = await kms.collection('examples').createKeyPair(
keyExchangeType: null, // no key exchange.
signatureType: SignatureType.ed25519,
);
final pk = await document.getPublicKey();
print("Public key: ${pk.bytes}");
// Sign a document
final signature = await document.sign([1,2,3]);
In the call to the sign
method I had the error, as I wrote, because in defaultSignatureImplementations
(I think it's from the "cryptography" lib) there's a null
in the list (don't know why - this is out of my control) and no null-check while using list items with the "singleWhere" statement here:
The desired "ed25519" implementation is the first element of the list, but
singleWhere
scans all the items in the list (not stopping at first match) so when you access the "name" property of the null
item, you have the error. Perhaps just a c?.name
would prevent the singleWhere
from causing the error but, in my opinion, having a null
in the list is still not good.What do you think? Is there something I'm missing or doing wrong , to prevent the
defaultSignatureImplementations
from containing a null
?from cryptography.
I have the same issue. Has there been any workaround to this?

The kms package is deprecated for now.
