DataBlock class
Encapsulates a block of data within a Data Matrix Code.
Data Matrix Codes may split their data into multiple blocks, each of which is a unit of data and error-correction codewords. Each is represented by an instance of this class.

Static Methods
-
getDataBlocks(
Uint8List rawCodewords, Version version) → List< DataBlock> - When Data Matrix Codes use multiple data blocks, they actually interleave the bytes of each of them. That is, the first byte of data block 1 to n is written, then the second bytes, and so on. This method will separate the data into original blocks.
