FilterState.filters stream not updated on FilterState.clear

[erf]

Describe the bug 🐛

I have a FilterState and listen to the filterState.filters stream for updates. When adding filters i receive updates, but not when calling filterState.clear.

To Reproduce 🔍

1. create a FilterState instance
2. listen to the FilterState.filters stream using a StreamBuilder
3. add filters and confirm we receive stream updates
4. add a button which calls filterState.clear and confirm the StreamBuilder does not receive an update

Expected behavior 💭

I'd expect StreamBuilder to receive an update when calling filterState.clear
