A friend of mind started a flutter project. He asked me if it is possible to set a button like the floating button of whatsapp and which will be movable by the user.
Here you need to code a container as a button and add a custom animation if that is the question you're asking.
If not What you are looking for is a Draggable widget. You can then handle the translation using onDraggableCanceled which is passed and offset that you can be used to update the placement - https://flutter.dev/docs/cookbook/effects/drag-a-widget
And there is a couple of animation we can do for a button in a flutter.
Refer to this - https://medium.com/flutter-community/animated-send-button-in-flutter-94c1834268b1
There are many ways to do this, for the sake of simplicity I would prefer you to check out Stack Widget, where you can give coordinates to each Widget(button in your case) and move them.

How do I make this bottom line in flutter? Like this
is this a draggable bottom sheet?
I've found a package for that:
https://pub.dev/packages/draggable_bottom_sheet
otherwise probably just a SizedBox with rounded borders

How To Use Wrap Function In Vs Code For Flutter Coding ?
I want to know shortcut key.
Select the code, than alt+Enter. You'll see below picture, now choose Extract method. Did you mean this?
You can wrap with Column/Row widget, then rename it to Wrap. Both provide children.
1st ctrl+shift+r on windows(default I think)

i have a gridView List and when i click on one I want it to enlarge to display more information almost like a dialog box over current content.
Something like this in the picture. Thank you in advance.
I can't paste the full code, but you might use a Stack as the simplest approach.
The easiest way, without animation, is having the GridView as the first child, and when clicking the Tile, pass the tile info, call setState()... and redraw the stack with whatever overlay u want with the selected content view.
When you get that in place, you might include Animated widgets to work on the transition.
Another options is to use Overlays, go to the bottom of this Medium article, to understand how it works, it is applied to a menu, but the same concept will work for you. Maybe this is a neater approach.
Another cool option might be the use of Hero animations, but I dont know if you can manage to use within the same BuildContext, depends on how you will build the view.
Best of luck!

I am using this library to add a TextField in Swift. I can see how to programmatically add it in code, but I want to know how to add it via the Xcode UI. I want to be able to position it in Storyboard.
I tried to edit this line
#IBOutlet weak var txtOlja: TextField!
but that had no effect.
You can only add it in Storyboard if the control was #IBDesignable.
Since this particular control can't be rendered in Interface Builder, your only option is to programmatically constrain it using Auto Layout.

How do I add a text to the right of the figure? I want to resize the plot to leave some empty space on the right and add some information there.
Thanks!!
If you want to put that text inside of a legend you can do:
legend('Some quick information','location','EastOutside')
That is easiest. For more control though, you can put a text box inside the figure window:
MyBox = uicontrol('style','text')
set(MyBox,'String','Here is a lot more information')
and move it around with:
set(MyBox,'Position',[xpos,ypos,xsize,ysize])
Try this for short text:
plot(1:5);
text(5.05, 2.5, 'outside', 'clipping', 'off');
Or this solution for more complex annotations:
