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.
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:

Bar View
After try develop this, I don't have success.
Any idea how to make this?

In iPhone we can show the batch number on the application icon. i want to do the same thing for Android application icon.
I have seen the same thing in Android "Message" application icon. I you receive one message, it will show "1" on the icon.
We can use Widget to do this. But I don't want to use Widget.
Is there any possibility to do this without widgets ?
Please give some idea about this.

No, sorry.
BTW, they are called "app widgets". "Widgets" are things like EditText and Button.
