The Method 'bloc' Isn't Defined For The Type 'BuildContext'

 Widget build(BuildContext context) {
    final appBar = AppBar(
      title: Text(
        "Romantic Comedy",
      ),
      actions: [
        IconButton(
          icon: Icon(Icons.search),
          onPressed: () {
            showSearch(
                context: context,
                delegate: MaterialSearch(_pagingController.itemList));
          },
        ),
      ],
    );

    return Scaffold(
        backgroundColor: Colors.black,
        appBar: appBar,
        body: BlocConsumer<MovieBloc, MovieState>(
            listener: (context, movieState) {

            },
            builder: (context, movieState) {
              if (movieState is MovieSuccessState) {
                movieBloc.movies.addAll(movieState.movies);
              }
              return GridView.builder(
                  controller: _scrollController
                    ..addListener(() {
                      if (_scrollController.offset ==
                          _scrollController.position.maxScrollExtent) {
                        context.bloc<MovieBloc>()
                          ..isFetching = true
                          ..add(Fetch());
                      }
                    }),
                  padding: EdgeInsets.only(left: 12.0, right: 12.0),
                  gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
                      crossAxisCount: 3),
                  itemBuilder: (context, index) => MovieTile(_movies[index]));
            }));
  }

After v6.1.0, both context.bloc and context.repository are deprecated in favor of context.read and context.watch. checkout the migration guide for more information.
