fromJson property
Optional callback that exposes the String representation of the state and returns the parsed state.
If it is not defined,it will be inferred form primitive:
- int: (String json)=> int.parse(json);
- double: (String json)=> double.parse(json);
- String: (String json)=> json;
- bool: (String json)=> json =='1';
If it is not defined and the model is not primitive, it will throw and ArgumentError.
Implementation
FutureOr<T> Function(String json)? fromJson;
