I try to implement in Flutter a similar Google Maps AppBar using CustomScrollView and SliverAppBar with an flexibleSpaceBar, but I don't found any option to display an widget only on "opened" state of AppBar.
The representation of result pretended is this:
Opened View
Bar View
After try develop this, I don't have success.
Any idea how to make this?
UPDATE
The needed effect is visualized in that gif:

Flutter floating overlay widget
i need help guys, What i do now?
What i'am doing picture
You can create a draggable chat button by checking below link. But it will be inside the application.
Inside app - https://medium.flutterdevs.com/draggable-floating-action-button-in-flutter-2149a7e47f06
If you want to draw the draggable view outside the application, check https://pub.flutter-io.cn/packages/system_alert_window plugin. Here, you need to do minor tweeks.
Apart from this, other approach is to write the code in native and access it to flutter via method channel
For native - https://medium.com/#kevalpatel2106/create-chat-heads-like-facebook-messenger-32f7f1a62064
I am learning flutter, and I found myself with the task of creating a floating button, that by minimizing the application the button is visible and overlaps any application, is it possible to create this functionality in flutter?
You should use Scaffold and there's a parameter called floatingActionButton. There you can add a button and it definitely won't overlay anything. You should also search for SafeArea and Listview/SingleChildScrollView. These are great widgets for avoid overlays. Flutter has a great documentation so you can always look up a widget in google and there will be always something.
I'm coding a quiz app. I want to achieve this. Everything is okay but the overlapping effect doesnt. I'm using pageview.builder to navigate between pages. How can i achieve this ?
I think you wish to have a carousel effect for your question cards.
A simple solution would be using ListView horizontally, also there are some packages that you would like to check, for example;
flutter_swiper
carousel_slider
I got a requirement to use the natively developed screen as a form of widget in the flutter code.
