getInt64 method Null safety

int getInt64 (
  1. int byteOffset,
  2. [Endian endian = Endian.big]
)

Returns the (possibly negative) integer represented by the eight bytes at the specified byteOffset in this object, in two's complement binary form.

The return value will be between -263 and 263 - 1, inclusive.

Throws RangeError if byteOffset is negative, or byteOffset + 8 is greater than the length of this object.

Implementation

int getInt64(int byteOffset, [Endian endian = Endian.big]);
