Flutter Health plugin fetch workouts in android

Question

I'm struggeling to fetch WORKOUTs with the flutter health plugin. I can establish a connection to google fit and I get STEPS but no WORKOUTs.

I tried it with version 6 and 7 of the plugin (https://pub.dev/packages/health/versions/6.0.0, https://pub.dev/packages/health/versions/7.0.1)

I always used the example. In the examples there is also the workout type included and I checked that in the query period there is also a workout. I can see the workouts in Google Fit.

static final types = [
HealthDataType.WEIGHT,
HealthDataType.STEPS,
HealthDataType.HEIGHT,
HealthDataType.BLOOD_GLUCOSE,
HealthDataType.WORKOUT,
HealthDataType.BLOOD_PRESSURE_DIASTOLIC,
HealthDataType.BLOOD_PRESSURE_SYSTOLIC,
// Uncomment these lines on iOS - only available on iOS
// HealthDataType.AUDIOGRAM

];

 List<HealthDataPoint> healthData =
          await health.getHealthDataFromTypes(start, end, types);

Anybody has an idea what's the issue?
