keepAlive about flutter_staggered_grid_view HOT 6 CLOSED

An example of a widget with this mixin

class Counter extends StatefulWidget {
  @override
  _CounterState createState() => _CounterState();
}

class _CounterState extends State<Counter> with AutomaticKeepAliveClientMixin {
  int counter = 0;

  @override
  Widget build(BuildContext context) {
    super.build(context);

    return Material(
      child: InkResponse(
        onTap: () {
          setState(() {
            counter += 1;
          });
        },
        child: Container(
          height: 200,
          width: 200,
          child: Text('$counter'),
        ),
      ),
    );
  }

  @override
  bool get wantKeepAlive => true;
}

addAutomaticKeepAlives is true by default to make it work you need to extend AutomaticKeepAliveClientMixin and

@override
bool get wantKeepAlive => true;

@override
  Widget build(BuildContext context) {
    super.build(context);
    return Wiget;
  }

Hi @YoneHsiung,

Can you write a complete solution that I would just have to copy/paste to test it please?
I had to rewrite everything about KeepAlive because of flutter/flutter#19380, and this PR might help me to fix things related to KeepAlives.
I will wait for it to be merged in order to dive deeper in this issue.
