# getUint64 abstract method

int getUint64(

1. int byteOffset, [
2. Endian endian = Endian.big

])

The positive integer represented by the eight bytes starting at the specified `byteOffset` in this object, in unsigned binary form.

The return value will be between 0 and 264 - 1, inclusive.

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

## Implementation

    int getUint64(int byteOffset, [Endian endian = Endian.big]);
