fromBigInt method
fromBig sets v = n, and returns v. The bit length of n must not exceed 256.
Implementation
void fromBigInt(BigInt n) {
if (n.bitLength > 32 * 8) {
throw ArgumentError('edwards25519: invalid field element input size');
}
final uint8List = Uint8List(32);
for (int i = 0; i < 32; i++) {
uint8List[i] = (n >> (i * 8)).toUnsigned(8).toInt();
}
setBytes(uint8List);
}
