HealthKitReporter.workoutRouteQuery: Unhandled Exception: type 'Null' is not a subtype of type 'List<dynamic>'

[mpillawa]

Describe the bug
Hi,
I am trying to read route data from Health App tracked with an Apple Watch. The route is correctly displayed in Health App. When trying to read the route data, I get following Exceptions:

[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: type 'Null' is not a subtype of type 'List'

To Reproduce
Here are my code fragments to read the data:

void _startUpdateStreams() async {
List identifierList = [SeriesType.route.identifier];

Predicate _timeIntervallPredicate = Predicate(
DateTime.now().add(const Duration(days: -7)),
DateTime.now().add(const Duration(days: 7)));

_workoutRouteUpdates(_timeIntervallPredicate);

for (int i = 0; i < identifierList.length; i++) {
final isSet = await HealthKitReporter.enableBackgroundDelivery(
identifierList[i], UpdateFrequency.immediate);
log.d('enableBackgroundDelivery for '+identifierList[i]+': $isSet');
}
}

void _workoutRouteUpdates(Predicate _predicate) {
final sub =
HealthKitReporter.workoutRouteQuery(_predicate, onUpdate: (serie) {
log.d('Updates for workoutRouteQuery');
log.d("serie.locations.length: " + serie.locations.length.toString());
});
log.d('workoutRouteQuery: $sub');
}

Expected behavior
Do not get an exception but get access to the location data.

Hi @mpillawa

Thank you for your report, unfortunately there is a lack of the api for workout routes, I will introduce it in the next closest release ASAP

[mpillawa]

Hi @VictorKachalov,

thank you for your quick reply. I am very excited about your plugin and look forward to the future extension to read route data. If you are interested, I will be happy to assist with testing early releases.

Hi @mpillawa

I am happy to announce, that the version 2.0.1 is submitted. It supports workout route queries. It might introduce a breaking change, as I removed the stream event handler for this query and the data is a ready date which is already saved in HealthKit. This allowed me to read all the route and location batches at one time, by providing a predicate.

Hi @VictorKachalov,

I tried the 2.0.1 update, but without success. After changing the code to workoutRouteQuery, I still get the exception:

[VERBOSE-2:ui_dart_state.cc(209)] Unhandled Exception: type '_InternalLinkedHashMap<String, dynamic>' is not a subtype of type 'List'
HealthKitReporter.workoutRouteQuery
package:health_kit_reporter/health_kit_reporter.dart:333

workoutRouteQuery

This is my code to call workoutRouteQuery. Obviously no magic inside:

Predicate _timeIntervallPredicate = Predicate(
DateTime.now().add(const Duration(days: -7)),
DateTime.now().add(const Duration(days: 7)));
List woRouteList =
await HealthKitReporter.workoutRouteQuery(_predicate);

Thanks for your support!

@mpillawa have you tried to run pod update? This new version consumes the original HealthKitReporter, which also introduces new code related to workout rout query

[mpillawa]

@VictorKachalov yes, after pod update I got the route data. Thank you very much !!!
