doubleToByte method

Uint8List doubleToByte(double value)

Converts a double-precision floating-point number to a little-endian byte array.

Takes a double value and creates a ByteData object with an 8-byte capacity, then sets the double value into the ByteData object using little-endian byte order. Finally, it converts the ByteData buffer to a Uint8List to obtain the byte array.

Parameters:

• value: The double-precision floating-point number to be converted.

Returns: A Uint8List representing the little-endian byte array of the double value.

Implementation

Uint8List doubleToByte(double value) {
  var buffer = ByteData(8)
      .buffer
      .asByteData(); // 8 bytes for a double-precision floating-point number
  buffer.setFloat64(
      0, value, Endian.little); // Assuming little-endian byte order
  return buffer.buffer.asUint8List();
}
