toJson method

@override int? toJson()

Serializes the integer value to JSON format.

Returns the raw integer value, which may be null if no value has been set. This allows the JSON representation to distinguish between an explicitly set 0 value and an unset (null) value.

Returns: The integer value, or null if no value has been set.

Example:

final field = JsonInteger('age');
print(field.toJson()); // null

field.value = 25;
print(field.toJson()); // 25

field.value = 0;
print(field.toJson()); // 0

Implementation

@override
int? toJson() {
  return rawValue;
}
