getInt64 method

int getInt64(
  1. int offset, [
  2. Endian endian = Endian.little
])

Reads 8-bytes as a signed integer.

The offset must satisy the relations 0 ≤ offset ≤ offset+8 ≤ this.length.

final Buffer buffer = Buffer.fromList([8, 16, 32, 64, 128, 8, 16, 32]);
final int value = buffer.getInt64(0);
print(value); // 2310355955765743624

Implementation

int getInt64(final int offset, [final Endian endian = Endian.little]) {
  return asByteData().getInt64(offset, endian);
}
