Unhandled Exception: Null check operator used on a null value

[EricConnect]

Hello. When I use your example. An issue was occur as the title.

Could you please update the example to provide a better way use redux_persist?
I debugged some details. I believe this bug is not belongs to you. Actually, when I use the io file store. It has the same issue.
If you can update the example and find a new way to initialized the redux state it will give me a big help.
Thank you very much.

Hi @EricConnect

I have a similar issue - how did you fix this?

Best, Daniel

Hi Daniel,

I remember my problem is lost one line in main.dart.

void main() {
WidgetsFlutterBinding.ensureInitialized();  // I lost this line, so always failed when init.
...

Best,
Eric
