operator []= method

void operator []=(String name, dynamic value)

Sets the value of a nested field within the model object.

Provides convenient assignment to fields within the nested model using bracket notation. This delegates to the model's []= operator. The model object must not be null (asserted at runtime).

Parameters:

• name: The name of the nested field to set (must match a field's JsonField.fieldName in the nested model).
• value: The new value to assign to the nested field.

Throws: An Exception if:

• The model object is null
• No field with the given name exists in the nested model

Example:

final field = JsonObject<AddressModel>('address');
field.value = addressModel;
field['zipCode'] = '10001'; // Set nested field value

Implementation

operator []=(String name, value) {
  assert(rawValue != null);
  if (rawValue == null) {
    throw Exception("Field $name does not exist");
  }
  for (final field in rawValue!.fields) {
    if (field.fieldName == name) {
      field.value = value;
      return;
    }
  }
  throw Exception("Field $name does not exist");
}
