setInt64 abstract method

void setInt64(
  1. int byteOffset,
  2. int value,
  3. [Endian endian = Endian.big]

Sets the eight bytes starting at the specified byteOffset in this object to the two's complement binary representation of the specified value, which must fit in eight bytes.

In other words, value must lie between -263 and 263 - 1, inclusive.

The byteOffset must be non-negative, and byteOffset + 8 must be less than or equal to the length of this object.
