Problems with FocusNode about flutter_chips_input

[danvick]

Can we by any chance get the fill stack trace?

any news on this problem?

[danvick]

Kindly let me know if this problem is fixed in version 1.8.0

[emmaxCreative]

Seems fixed.
I added if (mounted) before the setState() in the _onFocusChanged() because I had the same error again when changing to another page that uses the same chipsinput class. But its working now. Thanks for the fix.

[mohammadne]

@danvick Yeah, I'm still getting this issue on the dev version. I have a ChipsInput widget on a drawer and when the drawer is closed and reopened with a value in the input the error is thrown.
