deserializePayload method

@override int deserializePayload(RowsCoverageBuilder builder, ByteData byteData, Endian endianness, int offset,)

Call to deserialize only the payload, no header. The Builder is to allow passing the message to build into. returns a int with a serialized size

Implementation

@override
int deserializePayload(imc.RowsCoverageBuilder builder, ByteData byteData,
    Endian endianness, int offset) {
  var byteOffset = offset;

  // field lat
  builder.lat = byteData.getFloat64(byteOffset, endianness);
  byteOffset += 8;
  // field lon
  builder.lon = byteData.getFloat64(byteOffset, endianness);
  byteOffset += 8;
  // field z
  builder.z = byteData.getFloat32(byteOffset, endianness);
  byteOffset += 4;
  // field zUnits
  builder.zUnits = imc.ZUnitsEnum(byteData.getUint8(byteOffset));
  byteOffset += 1;
  // field speed
  builder.speed = byteData.getFloat32(byteOffset, endianness);
  byteOffset += 4;
  // field speedUnits
  builder.speedUnits = imc.SpeedUnitsEnum(byteData.getUint8(byteOffset));
  byteOffset += 1;
  // field bearing
  builder.bearing = byteData.getFloat64(byteOffset, endianness);
  byteOffset += 8;
  // field crossAngle
  builder.crossAngle = byteData.getFloat64(byteOffset, endianness);
  byteOffset += 8;
  // field width

  byteOffset += 4;
  // field length
  builder.length = byteData.getFloat32(byteOffset, endianness);
  byteOffset += 4;
  // field coff
  builder.coff = byteData.getUint8(byteOffset);
  byteOffset += 1;
  // field angAperture
  builder.angAperture = byteData.getFloat32(byteOffset, endianness);
  byteOffset += 4;
  // field range
  builder.range = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  // field overlap
  builder.overlap = byteData.getUint8(byteOffset);
  byteOffset += 1;
  // field flags
  builder.flags =
      imc.RowsCoverageBitfieldFlags(byteData.getUint8(byteOffset));
  byteOffset += 1;
  // field custom
  var customSSize = byteData.getUint16(byteOffset, endianness);
  byteOffset += 2;
  var customDData = List.filled(customSSize, 0);
  for (var i = 0; i < customSSize; i++) {
    customDData[i] = byteData.getUint8(byteOffset++);
