Takes data from a Stream<Measurement> and uploads it.
Also supports JSON encoding via the toJsonString method.

Methods
-
addEvent(
DataManagerEvent event) → void -
Add
eventto the events stream. -
close(
) → Future< void> -
Flush any buffered data and close this data manager.
After calling close the data manager can no longer be used.
override
-
configure(
{required DataEndPoint dataEndPoint, required SmartphoneDeployment deployment, required Stream< Measurement> measurements}) → Future<void> -
Configure the data manager by specifying the study
deployment, thedataEndPoint, and the stream ofmeasurementsevents to handle.override -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onDone(
) → Future< void> -
When the data stream closes, the onDone handler is called.
Default implementation is a no-op function. If another behavior is wanted,
implementations of this abstract data manager should handle closing of
the data stream.
override
-
onError(
Object? error) → Future< void> -
When an error event is send on the stream, the onError handler is called.
override
-
onMeasurement(
Measurement measurement) → Future< void> -
On each measurement collected, the onMeasurement handler is called.
inherited
-
toString(
) → String -
A string representation of this object.
override
Operators
-
operator ==(
Object other) → bool -
The equality operator.
