What happened?

when using 6.3.0, my app fails to build, complaining about:

../../AppData/Local/Pub/Cache/hosted/pub.dev/persistent_bottom_nav_bar_v2-6.3.0/lib/components/decorated_navbar.dart:22:38: Error: The argument type 'ImageFilter?' can't be assigned to the parameter type 'ImageFilter'.
 - 'ImageFilter' is from 'dart:ui'.
                  filter: decoration.filter,
                                     ^

The offending line looks to be this that was included in 6.3.0:
4598baf#diff-3adbdb99a3c97c27b2c508ad096f69cfc3e3c3b887d759ff776e713060d48026R22

Steps to reproduce

Use 6.3.0
run flutter clean && flutter build apk
fails.

Code to reproduce the problem

the error isn't in code, it's directly in the dependency

Further, looking at the latest commits, your own commits fail for the same reason, but somehow 6.3.0 was still allowed to get released. pinning to commit 1cf94f6 seems to work.

Hi, thank you for reporting this issue. Sorry for the inconvenience. I resolved this in #224. The fix is available in version 6.3.1 :)
