Hi,

Based on the shared information, we have checked the mentioned issue “Error occurred in the addPostFrameCallback method of the Flutter DateRangePicker”. We have checked the mentioned issue in 20.1.58 version and we are unable to reproduce the mentioned issue from our end. Also, can you please confirm if you are using the latest flutter version? Otherwise, kindly update to the latest flutter version and check still if you are facing same issue.

Failed to compile application.

This problem started after upgrade flutter to 3.x. Downgrade did not helped even after flutter clean
