constfactory
-
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

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 setterinherited
- answerConstraintElement → Element?
-
answerConstraintElement ("_answerConstraint") Extensions for
answerConstraint
no setterinherited
-
answerOption
→ List<
QuestionnaireAnswerOption> ? -
answerOption One of the permitted answers for the question.
no setterinherited
- answerValueSet → FhirCanonical?
-
answerValueSet A reference to a value set containing a list of values
representing permitted answers for a question.
no setterinherited
-
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 setterinherited

copyWith
→ $QuestionnaireItemCopyWith<
QuestionnaireItem> -
no setterinherited
- 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 setterinherited
- definitionElement → Element?
-
definitionElement ("_definition") Extensions for definition
no setterinherited
- disabledDisplay → FhirCode?
-
disabledDisplay Indicates if and how items that are disabled (because
enableWhen evaluates to 'false') should be displayed.
no setterinherited
- disabledDisplayElement → Element?
-
disabledDisplayElement ("_disabledDisplay") Extensions for
disabledDisplay
no setterinherited
- enableBehavior → FhirCode?
-
enableBehavior Controls how multiple enableWhen values are
interpreted - whether all or any must be true.
no setterinherited
- enableBehaviorElement → Element?
-
enableBehaviorElement ("_enableBehavior") Extensions for
enableBehavior
no setterinherited
-
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 setterinherited
-
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 setterinherited
- 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 setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
-
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 setterinherited
-
item
→ List<
QuestionnaireItem> ? -
item Text, questions and other groups to be nested beneath a question
or group.
no setterinherited
- linkId → String?
-
linkId An identifier that is unique within the Questionnaire allowing
linkage to the equivalent item in a QuestionnaireResponse resource.
no setterinherited
- linkIdElement → Element?
-
linkIdElement ("_linkId") Extensions for linkId
no setterinherited
- maxLength → FhirInteger?
-
maxLength The maximum number of characters that are permitted in the
answer to be considered a "valid" QuestionnaireResponse.
no setterinherited
- maxLengthElement → Element?
-
maxLengthElement ("_maxLength") Extensions for maxLength
no setterinherited
-
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).
