parse method

@override VINParsedResult? parse(Result result)

Attempts to parse the raw Result's contents as a particular type of information (email, URL, etc.) and return a ParsedResult encapsulating the result of parsing.

@param theResult the raw Result to parse @return ParsedResult encapsulating the parsing result

Implementation

@override

  if (result.barcodeFormat != BarcodeFormat.code39) {
    return null;

    return null;
  }
  try {
    if (!_checkChecksum(rawText)) {
      return null;
    }
    final wmi = rawText.substring(0, 3);
