Hey there! Sorry -- somehow missed this one. This problem often appears if you're creating & recreating the TextEditingController. Often times, with TextFields, you'll want to build a StatefulWidget that initializes the TextEditingController only once, rather than creating a new one on each build inside a StatelessWidget.

Thank you @brianegan for the comment, my goal was to avoid using stateful widget instead to have a stateless widget with a redux state.

Yah, in many cases you don't need to use StatefulWidgets, but there are just a few cases where ya have to use a StatefulWidget to hold onto certain Flutter classes that need to be retained for each build. This includes things like TabControllers, TextEditingControllers, etc... If you recreate these objects each time in the ViewModel you'll run into trouble.

Hey @Abgaryan :) Did my advice help at all, or do ya have any follow-up Qs?

Hey @brianegan, Thank you very much for your advice, I changed the screen from stateless to stateful now it works.

Hi Brian, (ding @brianegan)
What doyou mean when you say "If you recreate these objects each time in the ViewModel you'll run into trouble"?
Currently I am making a small app with infinite list (with LiveView.builder), and for each item wrapped in StoreConnector() I recreate TextEditingController() in onInit() and dispose in onDispose(). What can possibly go wrong?
