Code39 constructor

Code39({
  1. int? module,
  2. bool enableCheckSum = true,
})

Create a Code39 symbology with the default or required properties.

The arguments module must be non-negative and greater than 0.

Since Code 39 is self-checking, it is not normally necessary to provide a checksum. However, in applications requiring an extremely high level of accuracy, a modulo 43 checksum can be added, if the enableCheckSum is true.

Implementation

Code39({int? module, this.enableCheckSum = true}) : super(module: module);
