Please see the photos attached for the feature, or simply head to https://www.chrislorenzomusic.com and resize the window until you see the dropdown menu in top right corner appears and click on the menu to see the effect.
I'm not sure what this effect or feature is called, but was wondering what it's called and if it was possible to make something similar in flutter?
Before resizing the window
After resizing window the menu at top right corner appears
When clicking on the menu
When an app or widget behaves differently depending on the screen size or orientation it is considered responsive or has a responsive layout.
https://docs.flutter.dev/development/ui/layout/adaptive-responsive
The Menu itself can be created using a Scaffold with an AppBar and a Drawer. You can configure the AppBar to have the menu icon or the links depending on the size using LayoutBuilder and MediaQuery.of.

I have a basic layout where I am using a stack widget to hold my other widgets.. I have a side toolbar, inside that I have a pen menu on click of which a popup should appear. When i am clicking the pen menu an alert dialog appears but not in the expected place, what i mean is...
I am expecting a dialog like the one in the below image. Do I need to use any plugin to create a dialog like this with a chevron mark?enter image description here
As you are using Alert dialog, it will by default be aligned in center of your screen. In order to achieve what you are trying to, I would suggest using a plugin like this.
I am using SliverAppBar widget with some background image behind it. Since the image I will load will be dynamic, sometimes it can have light colors and can cause the back button (or any other action button) to be hardly visible.
As you can see in the screenshot below, I gave a little shadow to the app bar title using TextStyle & Shadow widgets, so it is much more visible than the back button.
You can try use "elevation" here is the Flutter link for more clarification: https://www.google.com/url?sa=t&source=web&rct=j&url=https://api.flutter.dev/flutter/material/SliverAppBar/elevation.html&ved=2ahUKEwiEpfiIn4TwAhWUH7cAHY9ECIwQFjACegQIBRAC&usg=AOvVaw0wCdyaVv3EA8ulVXXvaVMu
I'm asking how to disable Overlays to move when a Scaffold.of(context).showSnackBar is called like on my video below.
The same thing is happening when the keyboard appear. Sometime the blue floattingButton (+) don't come back to it's original position :-(
Thx in advance.
Problem animation
The FloatingActionButton going up when the Scaffold is displayed is something common to all default implementations.
Give a look to the "Bootom app bar" demo in the Gallery app. Press on the search button and you will see it coming up. Or just add a Scaffold to the app that is built with flutter create command.
This happens because of the way the FAB button is placed on the screen and the effect of displaying the Snackbar by the Scaffold.
The FAB button is displayed at the bottom of the content area of the Scaffold content. When the content area is shrinked to include the BottomAppBar, the FAB goes up with it. It has nothing to do with Overlay.
You have two options:
Either you create your own versión of the FAB which is not
controlled by the Scaffold.
Or you hack the Scaffold so the size of the SnackBar is not taken
into account.
For this second option you can try the following:
Go to the file /lib/src/material/scaffold.dart in your flutter installation and look for the line with the code snackBarSize: snackBarSize, inside the _ScaffoldLayout class.
Replace it with snackBarSize: Size(0.0, 0.0),
You will see that the FAB stays in its place.
During inspecting scaffold Flutter project (without any modification) with Flutter Inspector in some cases of toggling widgets in left bottom corner magnifying glass button appear.
Where is it come from and what is its purpose?
Attached screenshots show that this button exists only on Render Tree tab.
This button appears only after you turned on "Select Widget Mode" in Flutter Inspector and selected a first widget to inspect. In order to inspect another widget you first need to tap the magnifier FAB.
I have a popup panel which opens on a button click event. Popup panel height should be fixed and if contents of popup panel exceeds the height of popup panel, then a vertical scroll bar needs to be attached to it, and i should be able to scroll it to see the contents. I am displaying a flex table in the pop up and the flex table rows and columns vary for different kinds of inputs. so, if the flex table size is bigger than pop up, scroll bar should appear to pop up. I tried with overflow:scroll in my css, but it didn't work. is it because of the flex table? How to achieve this when i have different widgets place in my pop up? Can any body please help?
Thanks,
Sreenivas
Try adding a ScrollPanel into your PopupPanel and then a FlexTable into your ScrollPanel.
