# CrossmintErrorCode

> Flutter Enum

**Enum**

Typed error codes for programmatic exception handling.

```dart theme={null}
enum CrossmintErrorCode
```

Consumer code can `switch` on `CrossmintException.code` instead of parsing
string messages.  Codes are grouped by domain so related errors share a
common prefix (e.g. `signer*`, `wallet*`, `auth*`).
