My AutocompleteTextField widget doesn't changes after some code inside decoration property changes (after setState() is called in other widget). My hintText is not changing after the variable "nextSub" change it's value. My errorText is not changing when variable "_hasError" becomes true. I don't know if its something about the GlobalKey or maybe is missing some setState inside the class bellow: Link for better visualization of code: [https://pastebin.com/Y2Qkwu71](https://pastebin.com/Y2Qkwu71)
