I have a not scrollable Form with a BorderLayout. In the CENTER of this BorderLayout, I have made a scrollable Container with BoxLayoutY. Inside this Container are appearing more Container. When there are a lot of Containers the CENTER Container is scrollable, but the last element is nos visible, I have to go down with the focus to see the last Container. What I want to do is:
When a new Container appears in the CENTER Container , this Container must scroll down, revealing the last Container added...is like an auto-scrolling.
Any help?
What about :
componentOfLastContainer.requestFocus();
centerBigContainer.repaint();

Does anybody have a clue how to achieve expand/collapse animation for a given Container widget?
I tried to use ExpandablePanel but it is not what I really want, because I want to render a Column within a Container, and if the Container is collapsed I want to show only 150px from it, otherwise it should have the height of the content.
Clicking on the arrow the Container should toggle it's state.
Below are some images which represents the goal:
Collapsed
Expanded
The overflow error is thrown because when the column is collapsed there is no room to contain all the children inside the column.
What do we do when we have a column with children's height larger than the screen height? We use scrolling!
So you can wrap your column with SingleChildScrollView widget to make the column scrollable, so when it collapses it doesn't complain about the children's height, instead, the scrolling functionality handles them because you can scroll in a column even if it has very small width.
I am using a CustomScrollView and Slivers inside it and redendering the list using SliverChildBuilderDelegate. This works fine, but my requirement is to have a Fixed Container of height = height of screen/2 and inside that I want to render a list and and it can scroll as well, I am using CupertinoSliverNavigationBar [this cannot be replaced]. I am able to draw a Container and inside that I am able to show a list using Listview.builder, but the problem is I am unable to scroll the list, whenever I scroll it, it goes to top again, I want something Like, my CustomScrollView should be kept as it is, just I want to create a Scrollable Container of fixed height and the list inside that should scroll properly and CustomScrollView can also scroll, I have tried many widgets like Wrap, Rows, Columns, SingleChildScrollView, also tried NeverScrollPhysics() Behaviour for CustomScrollView but nothing is working out. Please Help!
I try to make a container who is on another container in the border like that:
I want do that without TextField. For the moment I have just
To be more clear it's like a textfield without a textfield.
You can use Stack and Positioned for this custom.😀
I currently have a ListView.builder of containers that expand once I tap it. However, I'd like the containers to center in on the expanded container that was tapped.

Expanded Container mockup
Currently, if I tap on No.2 from the Expanded Container mockup picture, the container will expand but it won't snap/focus on that container. I'd like to find a way to make this possible.
Thank you in advance!

I want to create some applications with widget ListView. When you scrolling up, image at first index will be expanded, and if you scroll again, next image will be expanded again, and if you scrolling down, image will be collapsed again.
Is it possible to create this with flutter?
