Do you know how can I make my keyboard go above all the content?
Because I can see that flutter thinks that my keyboard is like a container which needs some space.
The resizeToAvoidBottomInset property is use to specify the behavior for this case.
Just set it to false to make the keyboard go above your content:
Scaffold(
resizeToAvoidBottomInset: false,
...
)

I'm using the persisten_bottom_nav_bar package to handle the bottom navigation in our app. The issue I'm having is that when I call FocusScope.of(context).unfocus(); to get rid of the keyboard, the navigation bar goes dark for a second. Has anyone figure out how to fix this issue?
So I implemented the package incorrectly, I fixed it by changing the parameters to the ones below. The main issue was hideNavigationBarWhenKeyboardShows which was basically rendering the bottomAppBar every-time the keyboard closed.
PersistentTabView(
resizeToAvoidBottomInset: false,
hideNavigationBarWhenKeyboardShows: false
Tip: Add resizeToAvoidBottomInset: false to any screens with textFields to prevent a small white spacing in between the keyboard and the scaffold
Scaffold(
resizeToAvoidBottomInset: false,
i need your help because i am customizing my AppBar in flutter and i'd like to know if there is a way to decide what to show on the leading part: in my homepage i'd like to see a logo, but if i navigate to other screens i'd like to see the back button. So my question is: is there a way to write an AppBar class where, maybe with a statement, the device show the logo or the back button(seeing the navigation history)?
I hope you understand and thanks.
Sure, that's very simple:
In your home screen, pass your logo (can be any Widget) to the AppBar's leading argument.
On the other screens, pass nothing and set automaticallyImplyLeading: true - the AppBar will create a back button automatically.
Alternatively, if you only use one AppBar for the whole app, use this snippet:
AppBar(
leading: ModalRoute.of(context).settings.name == "MY_HOME_SCREEN_ROUTE" ? MyLogoWidget : null,
automaticallyImplyLeading: true,
...
);
I suggest you read this article to have different types of appbar:

I have an app that has a bottomNavigationBar() wrapped in a clipRRect() but the content doesn't show behind it. The same behaviour also happens with transparent SliverAppBar()s in NestedScrollView()s. How can I achieve this?
Edit: Here is an example of the SliverAppBar() problem. The shadow is being hidden by the app bar.
you can try this:
Scaffold(
extendBody: true,
extendBodyBehindAppBar: true,
and give a little padding to the top and bottom of you body content for overlapping at the very top and bottom.
When I use a pushNamedRoute(NewScreen.routeName)then automatically added the back arrow button how to delete that?
Please add automaticallyImplyLeading: false, into your Scaffold's Appbar
You can do it like Balaji Ramadoss mention. But if you don't want the user to be able to navigate to the last page, then rather use pushReplacementNamed(context, routename)
When I use Flutter, when the keyboard is closed, there will be a short white screen under the page before I can see the content.
It's because the body of the Scaffold gets resized when you open the keyboard
You can avoid the resizing with resizeToAvoidBottomInset: false or use another backgroundColor on the Scaffold
