O que costuma-se supor
Passing integers outside 0..255 to Hash.convert raises an ArgumentError or RangeError on invalid byte values.
O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.
Contrato
- sha256.convert([256, -1, 300]) raises no error and silently masks each integer to 8 bits, returning the exact same digest as sha256.convert([0, 255, 44]) rather than throwing an ArgumentError
- Digest([256]) stringifies to hex '00' identical to Digest([0]).toString() but evaluates to false under operator==
- Digest operator== returns false rather than throwing when compared with a hex String or byte List
- calling add() on a closed Hash chunked conversion sink throws StateError rather than ClosedException or silently accepting input
- calling close() repeatedly on a Hash chunked conversion sink is idempotent and raises no error
- calling add() on a closed HMAC chunked conversion sink throws StateError
