setFloat64 method Null safety
override
Sets the eight bytes starting at the specified byteOffset in this
object to the IEEE 754 double-precision binary floating-point
(binary64) representation of the specified value.
Throws RangeError if byteOffset is negative, or
byteOffset + 8 is greater than the length of this object.
Implementation
void setFloat64(int byteOffset, double value, [Endian endian = Endian.big]) =>
_unsupported();
