Workout metadata missing.

[ShineYang]

Describe the bug
When I use HealthKitReporter.workoutQuery(predicate) to retrieve workout data, harmonized.metadata always returns null.

To Reproduce
try { final workouts = await HealthKitReporter.workoutQuery(predicate); workouts.forEach((element) { print('metadata: ${element.harmonized.metadata}'); }); } catch (e) { print(e); }

Expected behavior
The metadata should look like this:
{HKAverageMETs: 4.85739 kcal/hr·kg, HKIndoorWorkout: 0, HKWeatherTemperature: 52.016 degF, HKWeatherHumidity: 7600 %, HKTimeZone: Asia/Shanghai, HKElevationAscended: 2403 cm}

Additional context
I think the reason might be that there's something wrong with Metadata.make()in the native code.
