getBigInt method

BigInt getBigInt(
  1. int offset,
  2. int length, [
  3. Endian endian = Endian.little
])

Reads a region of the buffer as a signed big integer.

Items are read from the range [offset : offset+length].

The range must satisy the relations 0 ≤ offset ≤ offset+length ≤ this.length.

final Buffer buffer = Buffer.fromList([255, 255, 31, 236, 95, 13, 82, 66, 20, 2]);
final BigInt value = buffer.getBigInt(0, buffer.length);
print(value); // 9818446744073709551615

Implementation

BigInt getBigInt(final int offset, final int length,
    [final Endian endian = Endian.little]) {
  return getBigUint(offset, length, endian).toSigned(length * _bitLength);
}
