如何在 Flutter Bloc 中执行 pull to refresh (LiquidPullToRefresh) 时刷新当前页面

问题描述

我在主屏幕上使用 bloc 方法。我想在主屏幕上拉动刷新... 我厌倦了太多的方法没有得到解决......你能提出一些解决方案吗。

在 onrefresh() 旁边，我添加了一些更改

1 . BlocProvider(
        create: (context) => ottGetAllMovie(httpClient: http.Client())
          ..add(FeedsFetched(widget.title,"homePage")),//child: HomePage(),child: ottGetHomeInnerCatPage(
            wtitle: widget.title,mixpanelinner: widget.mixpanel),)

2.    _FeedsBloc.add(FeedsFetched(widget.wtitle,"homePage"));

3. setState(() {
     _FeedsBloc.add(FeedsFetched(widget.wtitle,"homePage"));
 BlocProvider(
        create: (context) => ottGetAllMovie(httpClient: http.Client())
          ..add(FeedsFetched(widget.title,)

    });

解决方法

虽然

这似乎是您用来获取数据的方法

OttGetAllMovie(httpClient: http.Client())
          ..add(FeedsFetched(widget.title,"homePage")),

将您的身体包裹在液体中以提神

    LiquidPullToRefresh(
            key: _refreshIndicatorKey,// key if you want to add
            onRefresh: ()async{
//cal your data source
               OttGetAllMovie(httpClient: http.Client())
              ..add(FeedsFetched(widget.title,}
            child: ListView(),// scroll view
          );
