[Health: 11.1.0] Delete not working on iOS

[Fethi-Hamdani]

Plugin Name

health

Plugin Version

11.1.0

Device

Iphone 13 pro max

Operating System

iOS 18.1

Describe the bug

Due to Apple's Limitations on knowing the Read/Write permissions to Apple Health steps, I added a workaround to manually check the permission by writing a dummy data and deleting it, the return value is always false even though I made sure the value is available in Apple Health and being read normally

Steps to Reproduce

1 - Save a dummy data (0 steps) on a specified start and end date
2 - Read the dummy data using the same start and end date (confirm it is available)
3 - Delete the dummy data using the same start and end date

Expected Behavior

The delete function return type should be true and the value should be delete from Apple Health

Actual Behavior

The delete function return type is always false and the value is still available on Apple Health

I found a solution and found a bug. If you don't specify an end date inside the plugin, they use the same date, and Apple Health can't find a date to delete. Use a date like in my example, it works
BugFix:

final testWrite = DateTime.now();
final w = await health.writeHealthData(value: 1, type: HealthDataType.STEPS, startTime: testWrite);//w = true
final d = await health.delete(type: HealthDataType.STEPS, startTime: testWrite, endTime: DateTime.now());//d = true

A more correct way to fix the issue is to use different function in a swift side
