I have problem with widgets in CKEditor 4.3. How to allow widget insert other widget?
For example:
First widget has title and content. Second widget has left panel and right panel. How I can put second widget into first widget?
Thanks!
It's not possible yet. We had to block possibility to nest widgets while working on first Widget System implementation in CKEditor 4.3.
I reported a ticket for this feature. However, it may take a few major releases to remove this limitation, since it's a very complex thing.
Edit: Since CKEditor 4.5.0 Beta it is possible to nest widgets. If you want to test it quickly please check CKEditor 4.5 insert widget into other widget.

I have developed an application in Flutter Dart and used an Expanded widget in my application but wherever I used expanded widget, it destroyed my UI and converted that List into an infinite list with no data on it.
Please let me know that reason why does this occur and the potential solution.
Thank you everyone in advance
You can use the expanded widget inside the column and row. Sometimes with use of an expanded widget with the wrong widget will give the error in release mode while it is working in the debug mode.
Make sure you are using the expanded widget inside the column or row and that column and row should not be inside the scroll view or other scrollable widgets.
If still not clear then update the question with the widget hierarchy.
In the Flutter web apps, there is no default functionality which makes text and images in the app selectable.
Is there a way to enable selection functionality for text/image on web?
I did check SelectableText widget but it is only for text and I would need to use it over every text. Also, you can't select text in multiple SelectableText widgets at once, you can only select text in one of them. I'm looking for a solution to select all text in the app without making change to every text widget.
Let me know if there’s one step solution to achieve this thing in whole web app.
In Flutter 3.3, with the introduction of the SelectableArea widget, any child of the SelectableArea widget has selection enabled for free!
To take advantage of this powerful new feature, simply wrap your route body (such as the Scaffold) with the SelectionArea widget and let Flutter do the rest.
For a more comprehensive deep dive into this awesome new feature, please visit the SelectableArea API page.
Flutter Web currently does not support multiple text selection across SelectableText widgets.
However, there are some experimental widgets that people are currently working on. According to a guide available at:
Custom SelectableScope Widget
They have proposed a custom widget, a Selectable scope, which basically allows for anything within it to be selectable (currently text and images)
NOTE: THIS IS CURRENTLY UNDER EXPERIMENTATION AND MIGHT CHANGE AS MENTIONED IN THE PROVIDED LINK.
I want to see all children of a given widget at one place so that I can better model my app. The issue is, I am unable to see all children of any given widget at once, neither in VSC nor in online DartDevTools.
I have to manually travel to that child and then it is being in this widget tree diagram.
Currently there are many children of MaterialApp widget but since I have only visited the 3 screens visible in screenshot it is only showing them and no other ones. I couldn't find similar question and also didn't find any documentation regarding this. Any help is appreciated.
I am using ChangeNotifierProvider for state-management.
I'm trying to make my first app and I have a problem:
I made a gridview of longpress draggable widget who can be deleted when I move them on the corresponding drag target.
Everything works well when I create these widget as statelesswidget.
The problem is that when I try to put these widget in Stateful widget it doesn't work well..
The choosen widget isn't removed correctly
Does someone already had this problem?
(Sorry for my Bad english)
Thanks
i created a widget, say MyBox, which has many other widgets. i have to use that widget on different page, however on different page, the size of the widget is different, on some page it's smaller, on other page it's bigger. Just wonder is there any way in GWT to zoom in & out the widget? Thanks
You can set the width and height of a widget, and the normal kinds of "zooming" that happen with HTML will happen to your widget too. If you want inner widgets to resize automatically, check out Layout Panels in GWT 2.0 and later.
