Before I applied this cool Slidable package, I use flutter-redux architecture, and combination of ListView and ListTile.

This issue came up when I started to filter the ListTile, which means Redux Store automatically changed then rebuild multiple ListTiles at once.

[ejabu]

I think there must be a connection to this flutter/flutter#21350

and

flutter/flutter#11895

[ejabu]

I made repository here https://github.com/ejabu/slidable_redux_flutter

[letsar]

Hi @ejabu thanks for the repo, I'am going to look at this.

[letsar]

This is indeed related to flutter/flutter#11895.
If you change the Slidable by a simple TextField, you end up with the same issue.

return TextField(
  key: Key(widget.todo.id),
);

I reduced the possibilities for this to happen with the Slidable widget. I will published my pseudo-fix today.

[letsar]

Can you test with the 0.4.6 version I've just published?
If the closeOnScroll parameter is true (the default), this error should not happen.

[ejabu]

I already tested in both my example repo and main App repo. Both are working now.

Thanks a lot !

[ejabu]

btw is it okay for me to close this issue ? I don't know whethers it should be the issuer or the owner of the repo who is privileged to do this..

[letsar]

No it's good to me that you closed the issue 👍
