[Question] Returning or NOT Returning a nullable from deserializeWith ?

My code is implementing a fromJson method calling the **deserializeWith** method returning an optional.

- Is it safe for me to return a Beacon and not a Beacon? ?

- In which case a null will be returned from the **deserializeWith** method

Code would be simple to maintain if method is returning a non nullable value and throw exception when required

```
static Beacon? fromJson(String jsonString) {
return serializers.deserializeWith(
Beacon.serializer, json.decode(jsonString));
}
```
