I am trying to make a dropdown widget that appears from the location of the clicked widget. I know there are a lot of solutions on the internet already regarding this, however, none of the ones I found serve my specific needs.
Using dropdown packages: This does not work, as these widgets do not provide any way of customization. They are always just lists of items. What I want is a dropdown Container that I can fully customize.
Using dialogs: It is tough to customize the location of these dialogs. I want it to appear right at the location of the clicked button/widget.
The white circle here is the widget that is supposed to be clicked on
This is what is supposed to appear after clicking the circle. As you can see here it is not placed correctly. The circle in the widget and the circle we click should be on top of each other. And the dropdown itself should be a container not a list of widgets like here as opposed to a dropdown list.
I believe this question should provide you with an answer.
If not, feel free to say so.
(The answer points to this package: flutter_portal)

my job is to create a few widgets using widgetkit and swiftui, however the main project is build on uikit so I am not very good with swiftUI. Nevertheless, I would like to know whether I can add a graph inside of, for example, medium sized widget, and can the graph be scrollable to reveal more information? Or could it only be clickable? Thank you.
I know how widgets work, just interested in whether it is possible to create a scrollable graph inside of a medium sized widget.
I'm only just getting started with widgets myself, so happy to be corrected. But interactivity with widgets is very limited - effectively to taps and nothing else. They're designed more to be informational displays than interactive user interfaces.
If your widget is larger than the small size (the square one that takes up the same space as 2x2 app icons on the iPhone home screen), you can have multiple tap targets. For example, if your widget had a list of calendar items, you could set it up so that a user tapping on a specific item opened the app with a view showing that item in more detail.
So no, a scrollable graph isn't feasible. But what you can do is create a graph that shows a snapshot of data that a user is most likely to find useful when glancing at their home screen – and making sure that if they tap on it, they go straight through to a more interactive version of the same data.
If I do not click:
When I press the button in the red circle:
Hello, I want to ask. What widget can I use to get a design like this? When the red circle is pressed, another menu will appear and can be pressed to go to another menu. I tried using the dropdown button but it doesn't work as I want. I have also used ListTileTheme and ExpansionTile but it still doesn't work as I want. Anyone can share an opinion.
Flutter's core dropdown widget works almost exactly like your example, and there is a widget that extends it even further. You should then be able to nest further menus if that's what you need it to do. Flutter DropdownButton2
I am learning flutter, and I found myself with the task of creating a floating button, that by minimizing the application the button is visible and overlaps any application, is it possible to create this functionality in flutter?
You should use Scaffold and there's a parameter called floatingActionButton. There you can add a button and it definitely won't overlay anything. You should also search for SafeArea and Listview/SingleChildScrollView. These are great widgets for avoid overlays. Flutter has a great documentation so you can always look up a widget in google and there will be always something.
I would like to have a tab bar that looks like this:
Note the center "My ID" button.
So here is my main problem:
Obviously I need a SafeArea to deal with irregular shaped screens, which itself need to be embedded in a Container so I can give the bar its background color. But, by doing this, how can I create the "oversized" button at the center?
After spending several hours banging my head against the wall, found a not so elegant solution. (Hey, but it works)
Here's a picture of the result.
So the way I made it work is actually by having two layers.
On the base of the widget tree is a Stack which contains everything that is currently seen on this page.
The actual bar widget has the text and icons, (the My ID part has only text no icon, but a placeholder SizedBox is used in place of the icon otherwise would be there)
By using the stack, I am able lay the round icon on top of the entire bar much like a FloatingActionButton
As you can see in the below image, the search box is at the top right corner.
Sometimes this image will cover up the text underneath it. Is there a way to move the search box to some other place? For example, like Atom's or Sublime's search box.
NO, there is currently no way to move it.
There was discussion on this amongst the vscode developers: Find Widget UI enhancement.
We should definitely not make this move both vertically and
horizontally since we do not do this anywhere else in our UX.
Introducing such a new concept does not align well with our general
workbench UX which is not very flexible
Looking at the pictures the docked find widget at the top / bottom
feel too heavy for me.
The current find widget solution I like because it is similar to the
chrome experience which every user on the planet is familiar with
While implementing the docking solution, we found we can actually
split this two issues completely. For the issue of covering search
result, we can allow users to scroll beyond the first line by the
height of Find Widget. It doesn't change Find Widget at all, you can
only scroll beyond first line only when the Find Widget is visible so
it won't cover anything.
I made two changes to the Find Widget for this work item.
You can resize the Find widget horizontally
You can scroll beyond the first line when the find widget is visible.
Which gives us the only customizations we can do to the search/find widget if it (as you said) "covers up text underneath it":
You can adjust the width horizontally
You can set "editor.find.addExtraSpaceOnTop": true to allow "scroll beyond the first line when the Find Widget is visible"
