here is the one throwing the exception

Has anyone managed to fix this?

minhdanh commented 3 years ago

The issue has been mentioned here: https://github.com/Dimibe/sticky_grouped_list/pull/29#pullrequestreview-649497547 For now I think the solution for us is to fork the repo and fix it ourselves, until the author has time to fix this.

bettdouglas commented 3 years ago

Thanks, I ended up going that direction. Worked well

kimmanwky commented 3 years ago

Is anyone that fixed the issue and don't mind sharing their repo for temporarily solution?

minhdanh commented 3 years ago

@kimmanwky It's very easy, you can check my repo here: https://github.com/minhdanh/sticky_grouped_list/tree/feature/null-safety

However I ended up not using this package anymore, I used this instead: https://github.com/Dimibe/grouped_list (Same author, but more up to date I think)

Dimibe commented 3 years ago

Hi all, sorry for the late reponse. I will fix this problem most likely today and release a new major version with null safety.

Interesting! Let me check out the another package if it will suit better. Thanks!
