_splashBloc..add(SplashStartEvent() gives error 'owner!._debugCurrentBuildTarget == this': is not true."

return BlocProvider<SplashBloc>(
      create: (context) => _splashBloc..add(SplashStartEvent()),
      child: BlocBuilder<SplashBloc, SplashState>(
        builder: (context, state) {
          return SafeArea(
            child: Scaffold(
              backgroundColor: Colors.blueAccent,
              body: Center(

            ),
          );
        },
      ),
    );

.. usage gives following error, previously it's working fine.
