StsTestStep class

The test step for executing the Sit-to-Stand (STS) test.

Handles sensor streaming, provides real-time progress feedback for UI, and passes collected data to StsProcessor. The user interface is defined in StsTestStepUI. Used as part of the StsTask sequence.

Constructors

StsTestStep.new({required StsMeasure measure, required StsConfig config, required MobilityProbe probe, required StsProcessor processor, bool includeInstructions = true, bool includeResults = true})
Creates a test step for the STS test.

Properties

$type ↔ String?
The runtime class name (type) of this object. Used for deserialization from JSON objects.

completer ↔ CancelableCompleter<StsResult>
getter/setter pair
config → MobilityConfig
The configuration for this mobility step.
finalinherited
footnote ↔ String?
Optional footer text to be displayed below the question. This can be used to provide additional information, such as copyright, or instructions. This text will be displayed in a smaller font size.
getter/setter pairinherited
fromJsonFunction → Function
The function which can convert a JSON string to an object of this type.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
identifier → String
A unique identifier of the Step. This identifier connects the step to its result (RPResult) object.

includeInstructions ↔ bool
Show the instruction before the test?

includeResults ↔ bool
Show the results after the test?
getter/setter pairinherited
jsonType → String
Return the __type to be used for JSON serialization of this class. Default is runtimeType. Only specify this if you need another type.

measure → StsMeasure
The measure associated with this mobility step.
finalinherited
optional ↔ bool
Can this step be skipped? If so, the result for the step will be null.

probe → MobilityProbe
The probe used to collect mobility data.

realtimeProgressTracker ↔ StsRealtimeProgressTracker
latefinal
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stepWidget → Widget
The widget (UI representation) of the step.
no setterinherited
text ↔ String?
The text of the Step. Different types of Steps are using the text text differently.
