JsonUnsupportedObjectError class - dart:convert library (original) (raw)

Error thrown by JSON serialization if an object cannot be serialized.

The unsupportedObject field holds that object that failed to be serialized.

If an object isn't directly serializable, the serializer calls the toJsonmethod on the object. If that call fails, the error will be stored in thecause field. If the call returns an object that isn't directly serializable, the cause is null.
