Flutter Modal Sheet - flutter

I have seen and tried the 'showModalBottomSheet' widget in flutter, and thought whether there was a widget like 'top sheet modal'. like whatsapp when a message comes in. as below,
Thanks in advance.

If you need a 'top' modal sheet inside the app, try using the Banner widget: https://docs.flutter.io/flutter/widgets/Banner-class.html.
Otherwise, what is shown is screenshot is a notification which appears differently on iOS and Android.

Is there a way to pop up and dismiss screen like this in flutter?

I am familiar with how to do this in Swift, but is there a way to achieve the same result in Flutter? The screen should "popup" from the bottom and could be dismissed by swiping down.
There are a bunch of 3rd-party widgets to do it. They don't look exactly the same as the one described but they are highly customizable. Here are some from https://pub.dev/
awesome_select
backdrop_modal_route
bottom_sheet_expandable_bar
bottom_sheet

Can not open new full screen when push from tabview flutter

I met a problem with push method in FLutter. Firstly, I have a main screen included AppBar and body to control many screens. In child screen, I tried to push to another new screen, but it didn't open full-screen and it's attached with AppBar from mainscreen. How can I fix it or any recommend keywords?
Many thanks
The problem is from package https://pub.dev/packages/persistent_bottom_nav_bar. When I used Flutter default bottom navigation, the problem is solved.

Implement next,previous,home page,share button throughout my flutter app

1.I have created a lesson app USING FLUTTER in which I want to implement next,previous,share & home button in each page...How can I do this
2.I need your help
If you have a scaffold, this will have an appbar and you place the actions in the appbar with icon buttons.
A scaffold also has a body which can be a pageview which in turn, can hold your various pages.
Depending on the app, you might get the pageView or a gestureDetector to give you swipe left and right for your previous or next.
