The same issue for me, just pasted the example code and it gave the same error. This is the exact text of the error:

I've made a pull request with a solved version, @MarsadMaqsood can you merge that ? just to pass into the production version

Hi there! Same issue with me.
When I try to build iOS app I'm facing with this issue. It's started to happen after lastest Xcode and cocoapods updates etc.
Here is log;

../../../../../.pub-cache/hosted/pub.dev/stylish_bottom_bar-1.0.3/lib/src/bottom_bar.dart:421:21: Error: Cannot invoke a non-'const' constructor where a const expression is expected.

How can I fix this ?
