enter image description hereI followed a YouTube tutorial to connect OpenAI to a Flutter Flow application with the goal of creating a chatbot. I followed all the steps, but when I launch the test, either a blank gray page appears or an error page with an error message.

I watched the tutorial again and followed all the steps exactly, but the issue still persists. If you have another way to create a chatbot with OpenAI or if you have a solution, please help me.

Share HomePageWidget code,

Getting this error because you are showing something on UI which is null for eg.

String? data; // here data == null
Text(data!) // show error in UI

The solution is :
1 Give your variable some initial value

String data = ""; // hence data != null
Text(data) // shows nothing because string is empty, not null

2 OR Use if else condition like below

String? data; // here data == null
Text(data ?? "no data found") // shows no data found in UI

Happy Coding :)
