const

factory

QuestionnaireItem.fromJson(Map<String, dynamic> json)

Factory constructor, accepts Map<String, dynamic> as an argument

factory

QuestionnaireItem.fromJsonString(String source)

Acts like a constructor, returns a QuestionnaireItem, accepts a String as an argument, mostly because I got tired of typing it out

factory

QuestionnaireItem.fromYaml(dynamic yaml)

Factory constructor that accepts a String in YAML format as an argument

factory

Properties

answerConstraint → FhirCode?

answerConstraint For items that have a defined set of allowed answers (via answerOption or answerValueSet), indicates whether values other than those specified can be selected.

no setter, inherited

answerConstraintElement → Element?

answerConstraintElement ("_answerConstraint") Extensions for answerConstraint

no setter, inherited

answerOption → List<QuestionnaireAnswerOption>?

answerOption One of the permitted answers for the question.

no setter, inherited

answerValueSet → FhirCanonical?

answerValueSet A reference to a value set containing a list of values representing permitted answers for a question.

no setter, inherited

code → List<Coding>?

code A terminology code that corresponds to this group or question (e.g. a code from LOINC, which defines many questions and answers).

no setter, inherited

copyWith → $QuestionnaireItemCopyWith<QuestionnaireItem>

no setter, inherited

definition → FhirUri?

definition This element is a URI that refers to an ElementDefinition or to an ObservationDefinition that provides information about this item, including information that might otherwise be included in the instance of the Questionnaire resource. A detailed description of the construction of the URI is shown in Comments, below.

no setter, inherited

definitionElement → Element?

definitionElement ("_definition") Extensions for definition

no setter, inherited

disabledDisplay → FhirCode?

disabledDisplay Indicates if and how items that are disabled (because enableWhen evaluates to 'false') should be displayed.

no setter, inherited

disabledDisplayElement → Element?

disabledDisplayElement ("_disabledDisplay") Extensions for disabledDisplay

no setter, inherited

enableBehavior → FhirCode?

enableBehavior Controls how multiple enableWhen values are interpreted - whether all or any must be true.

no setter, inherited

enableBehaviorElement → Element?

enableBehaviorElement ("_enableBehavior") Extensions for enableBehavior

no setter, inherited

enableWhen → List<QuestionnaireEnableWhen>?

enableWhen A constraint indicating that this item should only be enabled (displayed/allow answers to be captured) when the specified condition is true.

no setter, inherited

extension_ → List<FhirExtension>?

extension_ ("extension") May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

no setter, inherited

fhirId → String?

id Unique id for the element within a resource (for internal references). This may be any string value that does not contain spaces.

no setter, inherited

hashCode → int

The hash code for this object.

no setter, inherited

initial → List<QuestionnaireInitial>?

initial One or more values that should be pre-populated in the answer when initially rendering the questionnaire for user input.

no setter, inherited

item → List<QuestionnaireItem>?

item Text, questions and other groups to be nested beneath a question or group.

no setter, inherited

linkId → String?

linkId An identifier that is unique within the Questionnaire allowing linkage to the equivalent item in a QuestionnaireResponse resource.

no setter, inherited

linkIdElement → Element?

linkIdElement ("_linkId") Extensions for linkId

no setter, inherited

maxLength → FhirInteger?

maxLength The maximum number of characters that are permitted in the answer to be considered a "valid" QuestionnaireResponse.

no setter, inherited

maxLengthElement → Element?

maxLengthElement ("_maxLength") Extensions for maxLength

no setter, inherited

modifierExtension → List<FhirExtension>?

modifierExtension May be used to represent additional information that is not part of the basic definition of the element and that modifies the understanding of the element in which it is contained and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and managable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions.Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

no setter, inherited

prefix → String?

prefix A short label for a particular group, question or set of display text within the questionnaire used for reference by the individual completing the questionnaire.

no setter, inherited

prefixElement → Element?

prefixElement ("_prefix") Extensions for prefix

no setter, inherited

readOnly An indication, when true, that the value cannot be changed by a human respondent to the Questionnaire.

no setter, inherited

readOnlyElement → Element?

readOnlyElement ("_readOnly") Extensions for readOnly

no setter, inherited

repeats → FhirBoolean?

repeats An indication, if true, that a QuestionnaireResponse for this item may include multiple answers associated with a single instance of this item (for question-type items) or multiple repetitions of the item (for group-type items).

no setter, inherited

repeatsElement → Element?

repeatsElement ("_repeats") Extensions for repeats

no setter, inherited

required_ → FhirBoolean?

required_ ("required") An indication, if true, that the item must be present in a "completed" QuestionnaireResponse. If false, the item may be skipped when answering the questionnaire.

no setter, inherited

requiredElement → Element?

requiredElement ("_required") Extensions for required

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

typeElement → Element?

typeElement ("_type") Extensions for type

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

inherited

toJsonString() → String

Another convenience method because more and more I'm transmitting FHIR data as a String and not a Map

toString() → String

A string representation of this object.

inherited

toYaml() → String

Produces a Yaml formatted String version of the object

Operators

operator ==(Object other) → bool
