Describe the bug

I want to get the weight and height of the user from apple health without specifying without specifying time interval or short time interval. I was not able to fetch these data if the date interval is a week or less. but it works if I change it to 2 months or so. and it also works I update my height and weight in the app health and try to fetch even for the 1-day intervals.

To Reproduce

Try to fetch height or weight date using these code sample.

var now = DateTime.now();
var startDate = DateTime(now.year, now.month, now.day - 1);
var endDate = now;

var healthData = await health.getHealthDataFromTypes(
    startDate,
    endDate,
    types,
  );

Expected behavior

To fetch height or weight data that is available on the user apple health without specifying a time interval or with a short time interval(1 day).=

Hey @yonycherkos

This is intended behaviour from the plug-in. Health looks for any data point with the given type in the interval you specified. If the user has not entered a weight during that time, then no datapoint will be returned.

When you look for the last 2 months it finds data, but maybe you didn't input weight & height data during the last day, so it seems like it doesn't work, but there are simply no data points during that time.

If I misunderstood the issue, feel free to write me or clarify the issue.
