This library decodes the discovery_b64 message that Zebra printers will send when they connect to a websocket endpoint, also named WebLink in the Zebra documentation.
- Decodes the raw base64 string into an easy to use strongly typed class.
- For backwards compatibility, the decoded value has a property
discoveryDataMapthat has the same entries as the Zebra SDK provides with thegetDiscoveryDataMap()function. - The decode process preserves the original source bytes per item.
- Each decoded item has an error value. This indicates if errors were encountered while decoding.
- A
discoveryobject has anerrorproperty that can be used to test if there was an error while decoding. - A
discoveryobject can be serialized to json for easy further processing

final discoveryB64 = "OiwuBAUBAAFaQlIAAEQzSjE5MzIwNjcyMgAAA....";
final discovery = Discovery.fromDiscoveryB64(discoveryB64);The discovery variable can be an instance of one of these types.

The DiscoveryAdvancedV4 is used for versions 4 and higher.
The actual type depends on version information provided in the discovery_b64 message.
This code aims compatibility with
- Link-OS multiplatform SDK 2.15.1
- WebServices v. 2.14.5198
Samples of decoded messages can be found in the test_resources folder.
