writeUint64LE function
Writes a 64-bit unsigned integer value in little-endian byte order to a list.
Implementation
List<int> writeUint64LE(int value, [List<int>? out, int offset = 0]) {
out ??= List<int>.filled(8, 0);
writeUint32LE(value & mask32, out, offset);
writeUint32LE((value >> 32) & mask32, out, offset + 4);
return out;
}
