blocProviders property
The BlocProvider list which is converted into
a tree of BlocProvider widgets.
The tree of BlocProvider widgets is created in order meaning
the first BlocProvider will be the top-most BlocProvider and
the last BlocProvider will be a direct ancestor of the child Widget.
Each provider's child will be discarded, so giving child to each
provider makes no sense.
Implementation
final List<BlocProvider> blocProviders;
