value property

@override double get value

Returns the double value of this field.

If the underlying rawValue is null, this getter returns 0.0 as a default value. This ensures that double fields always provide a valid numeric value when accessed, which is useful for calculations.

Returns: The double value, or 0.0 if rawValue is null.

Example:

final field = JsonDouble('price');
print(field.value); // 0.0 (default)

field.value = 19.99;
print(field.value); // 19.99

Implementation

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

@override set value (dynamic value)

Sets the double value, accepting multiple input types with automatic conversion.

This setter provides flexible input handling:

• double: Assigned directly to rawValue
• int: Converted to double using toDouble()
• String: Parsed using double.tryParse(). If parsing fails, rawValue is set to null
• null: Sets rawValue to null
• Other types: Attempts conversion via toString() and parsing. If that fails, rawValue is set to null

Parameters:

• value: The value to set, which can be a double, int, String, null, or other types (with fallback conversion).

Example:

final field = JsonDouble('price');
field.value = 19.99;      // Direct double
field.value = 25;         // Integer → 25.0
field.value = "29.99";    // String → 29.99
field.value = "invalid";  // Sets rawValue to null

Implementation

@override
set value(dynamic value) {
  if (value == null) {
    rawValue = null;
    return;
  }
  if (value is double) {
    rawValue = value;
    return;
  }
  if (value is int) {
    rawValue = value.toDouble();
    return;
  }
  if (value is String) {
    rawValue = double.tryParse(value);
    return;
  }
  // Attempt to handle other data types via conversion
  try {
    rawValue = double.tryParse(value.toString());
  } catch (_) {
    rawValue = null; // Fallback if conversion fails
  }
}
