Steps to Reproduce

When calling the API and requesting data in descending order by number, it returns in ascending order instead. However, when I use a mobile device to call this API, it works correctly.

Could you provide a reproducible example for this?

[sherrylin728]

I've identified the root cause and fixed it.
In JavaScript (which Flutter web relies on for web applications), the order of keys in an object is not guaranteed to be preserved. This means that when you decode a JSON string and convert it to a Dart map, the keys may appear sorted even though the original JSON data was unordered.
This issue will be closed. Thank you.
