How to call Navigator.push in FutureBuilder

[rafael....@gmail.com]

I want to redirect to another page after the future is resolved, this is a code sample of what I want

FutureBuilder(
                future: _bloc.formResponse,
                builder: (context,AsyncSnapshot<Result> snapshot){
                  if(snapshot.hasData){
                      Navigator.pushNamed(context, "/home");
                  }
                  return _buildSignUpPage();
                }
            )

but the previous code returns an exception

I/flutter (29158): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═════════════════════════════════════════════
I/flutter (29158): The following assertion was thrown building FutureBuilder<Result>(dirty, state:

FutureBuilder is a widget that builds and rebuilds its subtree based on interaction with a Future. What you want is just to call a function upon completion of the Future. For that just use _bloc.formResponse.then((_) => Navigator.pushNamed(...));
