EasyRefresh 无法上弹

[WuMingke]

如下demo，搭配 AnimatedList，EasyRefresh 在执行刷新动画时点击按钮，完成刷新后，无法上弹：

void main() {
  runApp(const MyHome());
}

class MyHome extends StatelessWidget {
  const MyHome({super.key});

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: Scaffold(
        body: SafeArea(child: MyBody2()),
      ),
    );
  }
}

class MyBody2 extends StatelessWidget {
  const MyBody2({super.key});

  @override
  Widget build(BuildContext context) {
    final animatedListKey = GlobalKey<AnimatedListState>();
    final data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

    return EasyRefresh(
      child: CustomScrollView(
        physics: const AlwaysScrollableScrollPhysics(),
        slivers: [
          SliverToBoxAdapter(
            child: SizedBox(
              height: 500,
              child: AnimatedList(
                key: animatedListKey,
                shrinkWrap: true,
                scrollDirection: Axis.vertical,
                initialItemCount: data.length,
                itemBuilder: (context, index, animation) {
                  return FadeTransition(
                    opacity: animation
                        .drive(CurveTween(curve: Curves.easeIn))
                        .drive(Tween<double>(begin: 0, end: 1)),
                    child: SizedBox(
                      height: 100,
                      child: Text(key: ObjectKey(index), 'data ${data[index]}'),
                    ),
                  );
                },
              ),
            ),
          ),
          SliverToBoxAdapter(
            child: Row(
              mainAxisSize: MainAxisSize.min,
              children: [
                ElevatedButton(
                  onPressed: () {
                    /// 点击循环列表
                    final index = data.length - 1;
                    final item = data[index];
                    animatedListKey.currentState?.removeItem(index,
                        (context, animation) {
                      return const SizedBox.shrink();
                    });
                    data
                      ..removeAt(index)
                      ..insert(0, item);
                    animatedListKey.currentState?.insertItem(0);
                  },
                  child: const Text('loop'),
                ),
              ],
            ),
          )
        ],
      ),
      onRefresh: () {
      },
    );
  }
}
