Bloc: Migration to bloc_test 7 issue

[Ferdzzzzzzzz]

Hey, so I've got a Cubit that initialized with an initial "event" (FeedCubit(...)..fetchFeed(...)) , a couple of the tests used to look something like this:

blocTest<FeedCubit, FeedState>(
        'Increments Reaction count on React Event',
        build: () **async** {
          when(mockReactToPost(any)).thenAnswer(
            (_) async => Right(tPostReact),
          );

        when(mockGetFeed(any)).thenAnswer((_) async => Right(tFeed));
        when(mockGetFeedPosts(any)).thenAnswer((_) async => Right(feedPosts));

        **await feedCubit.fetchFeed(...);**

          return feedCubit;
        },
        act: (cubit) {
          cubit.reactToPost(
            feedId: tFeed.id,
            postId: tPostId,
            reactionId: tReactionId,
          );
        },
        expect: [
          FeedState.loaded(
            feed: tFeed,
            feedPosts: tFeedPostsIncremented,
            currentFeedView: CurrentFeedView.postListView,
          ),
        ],
      );

But now the build param doesn't take a Future. I've been trying a couple of different ways to get that initial "Event" to fire off but haven't been successful. Any help is appreciated 😄

Ok I read the docs 👍
