Responding to client with driver.setValue() result: null

I am using Appium flutter driver to automate flutter app, but face below problem for sendkeys();

I am not able to use sendkeys(); method to pass value to the widgets.
I am able to perform click actions on the same, but while passing a text field to it I get " Responding to client with driver.setValue() result: null " error on the appium logs.

Attaching the appium server logs

FYI, I did add a wait condition to make sure the scripts are in sync with the app.Appium_301222.txt (120.4 KB)

Any updates on this?
