toJson method

  1. @override
Map<String, dynamic> toJson({
  1. OptimizeFor optimizeFor = OptimizeFor.put,
})
override

Converts this object into JSON format.

optimizeFor lets the program know what information to include in the JSON data map.

  • OptimizeFor.put (the default value) is used when making a data map that is being placed in a PUT request. This only includes data that has changed.
  • OptimizeFor.putFull is used when a parent object updates; so, all of the children are required to be present for the PUT request.
  • OptimizeFor.post is used when making a data map for a POST request.
  • OptimizeFor.dontOptimize is used to get all of the data contained in this object.

Throws InvalidIdException if owner.id is empty and optimizeFor is not set to OptimizeFor.dontOptimize.

Implementation

@override
Map<String, dynamic> toJson({OptimizeFor optimizeFor = OptimizeFor.put}) {
  // PUT
  if (identical(optimizeFor, OptimizeFor.put)) {
    Map<String, dynamic> toReturn = {};

    if (!identical(type, originalType)) {
      toReturn[ApiFields.type] = type.value;
    }

    return toReturn;
  }

  // PUT FULL
  if (identical(optimizeFor, OptimizeFor.putFull)) {
    return {
      ApiFields.type: type.value,
    };
  }

  // DEFAULT
  return {
    ApiFields.type: type.value,
    ApiFields.id: id,
    ApiFields.idV1: idV1,
    ApiFields.owner: owner.toJson(optimizeFor: optimizeFor),
    ApiFields.metadata: {
      ApiFields.controlId: controlId,
    },
    ApiFields.button: {
      ApiFields.lastEvent: lastEvent,
    },
  };
}
