bigInt method
The message digest as a BigInt.
If endian
is Endian.little, it will treat the digest bytes as a little
endian number; Otherwise, if endian
is Endian.big, it will treat the
digest bytes as a big endian number.
Implementation
BigInt bigInt({Endian endian = Endian.little}) =>
toBigInt(bytes, msbFirst: endian == Endian.big);
