Answer 1

Use Visibility widget and put your containers into a stack

bool isVisible = true;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: Text(widget.title),
        ),
        body: stackedContainers()
    );
  }

  Stack stackedContainers() {
    return new Stack(
      children: <Widget>[
        myContainer(),
        GestureDetector(
          child: background(),
          onTap: () {
            setState(() {
              isVisible = false;
            });
          },
        )
      ],
    );
  }

  Container myContainer() {
    return Container(
      child: Visibility(
        visible: isVisible,
       //.....
