pull_to_refresh_notification's Issues

滚动条 jumpTo到顶部 会触发刷新 

headerSliverBuilder: (BuildContext context, bool innerBoxIsScrolled) {
          return [
            SliverAppBar(
              // forceElevated: innerBoxIsScrolled,
              title: Text(widget.title),
              actions: widget.actions,
              flexibleSpace: widget.flexibleSpace,
              expandedHeight: widget.expandedHeight,
            ),
            PullToRefreshContainer((info) => PullToRefreshHeader(info: info)),
            SliverTabBar(
              child: TabBar(
                controller: tabController,
                isScrollable: widget.isScrollable,
                onTap: (int index) => tabBarOnTap(context, index),
                tabs: [
                  for (final tab in widget.tabs) Tab(child: Text(tab.name)),
                ],
              ),
              pinned: true,
            ),
          ];
        }
PrimaryScrollController.of(context)!.jumpTo(widget.expandedHeight ?? 0);

希望可以开放部分参数

希望可以开放此参数

// When the scroll ends, the duration of the refresh indicator's animation
// to the RefreshIndicator's displacement.
const Duration _kIndicatorSnapDuration = Duration(milliseconds: 150);

有些需求只是下拉放大图片。

现在回弹需要等待该时长。

很怪

为什么我设置的滑动监听，没有反应？

代码如下，打印一直没有输出。

Scaffold( appBar: new MyAppBar( child: Container( color: Colors.white30, child: Text("Title"), ), ), body: PullToRefreshNotification( onRefresh: _onRefresh, maxDragOffset: 250.0, notificationPredicate: (info) { print("---1----->${info?.metrics?.pixels}"); return true; }, child: CustomScrollView( controller: _scrollControler, slivers: <Widget>[ PullToRefreshContainer((info) { var offset = info?.dragOffset ?? 0.0; return SliverToBoxAdapter( child: Stack( children: <Widget>[ new Container( height: 240 + offset, width: double.infinity, child: Image.asset( "images/img_mine_top_bg.jpg", fit: BoxFit.cover, ), ), ], ), ); }), SliverList( delegate: SliverChildListDelegate(_listItem()), ) ], ), ), );

嵌套nested_scrollview刷新过程中，下啦往上滚动，会触发bug

use NestedScrollView . Automatically pull down and refresh every 15 seconds or so.

I don't do anything, it will automatically trigger a pull-down refresh at this frequency.

why?I sincerely need help, thank you!

Delay pull back

Hey,
Currently the refresher pulls back immediately after returning true in the onRefresh function.
It would be nice to have a little delay to the pull back, so the user would be able to see the text longer after the refresh is done.
Maybe add a delayPullBack property that accepts a duration.
Thanks.
