v2.3.1

⚠️ Breaking Changes ⚠️

Even though this is a patch release, it depends on flutter_chat_core, which introduced a small breaking change. I realized I didn’t bump flutter_chat_ui to a new minor version before publishing - sorry about that!

Fix is simple: if you have a custom ChatController, the set operation now requires a messages array.

1. If you were using named parameters like set(messages: messages), change it to: set(messages)
2. If you previously used set() with no arguments, replace it with: set([])
