Hi @genevaspur @adham-ashraf77, could either of you provide a complete minimal sample that we can use to verify this behaviour? I ran the sample found in https://api.flutter.dev/flutter/cupertino/CupertinoDatePicker-class.html and I didn't notice any lag. The frame rate was around 56fps in debug mode and around 60fps in profile mode.

What platforms are you experiencing this issue on?

Please provide the output of flutter doctor -v as well.
