Issue with ASN1Null #26

Closed dpjanes closed 5 years ago

dpjanes commented 5 years ago

I'm new to ASN1, but this feels to me like it should work

import 'package:asn1lib/asn1lib.dart';

main(List<String> arguments) {
    ASN1Sequence inner = ASN1Sequence();
    inner.add(ASN1Null());

    print("${inner.encodedBytes}");
}

But instead we get

NoSuchMethodError: The method '<=' was called on null.
Receiver: null
