toJSON method

  1. @override
double? toJSON()
override

Converts the double field to a JSON-compatible format.

Returns the underlying rawValue, which can be a double or null.

This method is used during serialization to include the field in the JSON output.

Example:

JsonDouble priceField = JsonDouble("price");
priceField.value = 19.99;

Map<String, dynamic> json = {"price": priceField.toJSON()}; // {"price": 19.99}

Implementation

@override
double? toJSON() {
  return rawValue;
}
