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)

I am trying to implement a feature in Flutter in which user will be able to display additional information after clicking on the specific icon or image. I would like to display a small annotation above selected icon. The example of what i would like to achive is in the screen below.
Is there any ready to use widget for this feature?
you can use Tooltip widget for this as bellow
Tooltip(
message: "This is the tool tip",
child: Icon(Icons.add),
),
when you long press on the icon the message will be shown like this.
You can do this by using Stack. Place the Button first where you want the Stack to be.
You can write the information you want to put on top of the button in Positioned() inside the Stack.
Set a variable, show information when this variable is True otherwise hide it.
You can also use GestureDedector if you want it to close when you touch anywhere.
I've looked through many tutorials for the side nav drawer. I can create one that works fine to lead to different pages. However, when I travel to a page that's different from home, it only gives me the arrow icon to go back to home at the top left instead of keeping the button to bring me back to the side navbar. How can I prevent this?
I can't use the home page to navigate everywhere because it's just supposed to be a blank splash screen.
You can define your drawer in a separate widget file, that you can import everywhere you have a scafold.
I created a package for it because I was missing similar functionality. If you want a Flutter approach for this navigation check out: https://api.flutter.dev/flutter/material/NavigationRail-class.html
Or if you want to have a look at my package: https://pub.dev/packages/side_navigation
It's because you're moving to a new page/Scaffold (probably using Navigator.push()). So, the default button in the AppBar will be the back button.
You can either have the same Drawer in every Scaffold you navigate to, which is not recommended since you'll just keep pushing routes to the navigation stack.
Or, you can change pages within the Scaffold. Check the interactive examples in BottomNavigationBar and NavigationRail to get an idea of how to do it. Basically instead of calling Navigator.push() when a tile in Drawer is tapped, just update the selected index and call setState().
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 a drawer in my
app. When I long tap it, "Open navigator menu" pops up. How can I change this? I already tried changing somethings in drawer.dart etc. but it didn't work.
it depends which action you use.
if you want different tap behaviour you can user GestureDetector
with Default drawer class, use Scaffold.of(context).openDrawer(); to open drawer with text in GestureDetector.
I created an application in flutter where I put Raisedbutton's everywhere. I want to change them all in Neumorphicbutton. Is there a way to change all Raisedbutton's into NeummorphicButton without editing one by one?
Thank you.
You can use refactor tool to change all occurrence of Raisedbutton to Neumorphicbutton. If u want to change all of them at once
Assuming that you want all the buttons to change into a neumorphic button style by clicking a single button , you can use the Onpressed() function and have it call SetState , in which you can change each and every button to Neumorphic style
