+# 17. Remove `setState` for reply message
+
+Date: 2024-03-01
+
+## Status
+
+Accepted
+
+## Context
+
+- Change from `bool replyEvent` to `ValueNotifier replyEventNotifier`.
+- When click on reply button, we will update `replyEventNotifier` and show the reply message.
+- Remove `setState` for reply func.
+
+## Consequences
+
+- We're make sure for first time click on reply button, it's work well.
+- We are limited to 1 use of `setState` for responding to events.
+- We're migrating `Chat` to phase out funcs that use setState.
+In addition to the reply message, we will continue to migrate other functions
