value property

@override double get value

Gets the double value of this field.

If the underlying rawValue is null, this getter returns 0.0 by default. This ensures that the field always provides a double value when accessed.

Implementation

@override
double get value => rawValue ?? 0;

@override set value (dynamic value)

Sets the value of this field.

The value can be a double, String, or null.

• If value is a double or null, it is directly assigned to rawValue.
• If value is a String, it attempts to parse it into a double using double.tryParse.
  • If parsing succeeds, the parsed double is assigned to rawValue.
  • If parsing fails (e.g., the string is non-numeric), rawValue is set to null.

Examples:

JsonDouble priceField = JsonDouble("price");

// Setting with a double
priceField.value = 19.99; // rawValue is 19.99

// Setting with a numeric string
priceField.value = "29.99"; // rawValue is 29.99

// Setting with a non-numeric string
priceField.value = "abc"; // rawValue is null

Implementation

@override
set value(dynamic value) {
  if (value is double?) {
    rawValue = value;
    return;
  }
  if (value is String) {
    rawValue = double.tryParse(value);
    return;
  }
}
