  Widget build(BuildContext context) {
    return fetchDummyData(context).toBuild<String>(
        onSuccess: (data) {
          return Text(data);
        },

        color: context.colorScheme.onBackground,

              context.navigation.canPop();
            },
          ),
          FloatingActionButton(
            onPressed: () {
              context.pop();
            },
            child: Text('Navigation Pop'),
          ),
          FloatingActionButton(
            onPressed: () {
              context.navigateName('/hello');
            },
            child: Text('Navigation Named'),
          ),
           FloatingActionButton(
            onPressed: () {
              context.navigateToPage(HomeViewDetail(), type: SlideType.TOP);
            },
            child: Text('Navigation Named'),
          ),
          FloatingActionButton(
            onPressed: () {
              context.navigateToReset('/hello');
            },

          ),
        ],
      )
