DataBlock class

Encapsulates a block of data within a QR Code.

QR 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, ErrorCorrectionLevel ecLevel) List<DataBlock>
When QR Codes use multiple data blocks, they are actually interleaved. 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.
