  - convert
```
Object convert(Object data)
```

    the new converter, or this converter if delegate is null
  - nullOr
```
default ValueConverter nullOr()
```
    Return a new converter that will call this converter only when the input is not null.
    
    Returns:
    
    the new converter; never null
  - passthrough
