getFloat64 method Null safety

double getFloat64 (
  1. int byteOffset,
  2. [Endian endian = Endian.big]
)

Returns the floating point number represented by the eight bytes at the specified byteOffset in this object, in IEEE 754 double-precision binary floating-point format (binary64).

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

Implementation

double getFloat64(int byteOffset, [Endian endian = Endian.big]);
