I had problem when keyboards up, The error occured "bottom overflowed by xx pixels".
So I resolved the problem by Wrapping column with SingleChildScrollView, and I wonder how It can happen? I s there special trick with SingleChildScrollView?
It happens because the keyboard takes up padding space from screen estate. So wrapping the column with SingleChildScrollView() essentially handles that by making your screen scrollable.
Hope this helpsā
Edit:
Also the second solution given by #EdwynZN is perfectly alright.
It just has one issue, if you have textfields that are in the region where the keyboard lies, the user won't be able to see them until they lower their keyboard. And that isn't considered a good UX practice.
So using SingleChildScrollView() is the best way to go, in regards to UI/UX.
SingleChildScrollView allows to scroll an area of the space if there is not enough to show the widget (in this case the column). When the keyboard appears the amount of space of the screen is reduced and it shows the overflow because the column cannot show the whole list of children, that's why you would need a scroll area. Another solution if you don't need to scroll is to change the parameter resizeToAvoidBottomInset: false in the scaffold

When I touch the keyboard it has such a height. This also gives an overflowed error
Well if you need the Scrolling effect in your screen, It's best to adjust all the elements inside a SingleChildScrollView() widget. But if you think you won't need that. All you want is to get rid of the jumping from bottom, the easiest way you can achieve this is by enabling this
resizeToAvoidBottomInset: true,
in your Scaffold() widget.
Problem summary
I'm building simple animation in which, simply, a panel expands to the right on a onTap event. The layout can be summarized as follows:
The panel has many tiles. Each tile has its own:
leading icon
title text
trailing icon
Each tile, when expanded, shows the three widgets above
Each tile, when shrinked, just shows the leading icon
The panel is scrollable to hold many icons such as these
At the end of the panel there's a simple icon which, when tapped, triggers the "expand" or "shrink" animation
The animation is built with an AnimatedContainer on the panel and a SizeTransition on the single tiles (via one single controller on the parent class)
The problem is simple: when the tiles shrink, their inner text overflows in the row.
Sample code
I just made this reproducible example on DartPad.
The obvious solution isn't helping me out
The most obvious solution is to simply wrap the Text inside a Flexible Widget: this advised by Flutter's docs and it makes sense, but unluckily it completely breaks my Layout.
Flexible introduces a flex factor that in this context is 100% unwanted.
I want my leading icons to be always at the end of the row, so my Spacer widget should "prevail" there.
I can't just play with flex factors there, as it would unintendedly hide text depending on its value.
Another code smell
Another thing I really don't like is the fact that I have to build a controller on the parent class, but I'm not actually using it on the parent class (I'm just exploiting it so I can give it to the children).
I'm new to animations in Flutter so I'm kinda confused on how I should orchestrate the whole thing here.
Any help will be appreciated / upvoted / accepted. Thank you!
As far as I understood you in a right way you just need set sizes for Row inside of SizeTransition instead of Container sizes
Here is your modified sample https://dartpad.dev/?id=a2408d29a1e8c6ce7a1cef8f21e7491d
I'd try an OverflowBox or a FittedBox (wrapping your text), depending on the result you want to achieve.
Even though there is absolutely no gap between my positioned widgets there is a glitchy visual gap between them. I have my Stack in an InteractiveViewer and when I zoom in and out and move about they become randomly more or less visible.
This happens with any Positioned widgets in a Stack so I've not provided any specific code of mine.
This ui looks like there is nothing that's being stacked. If you are using positioned widget then the value given maybe a problem. For this layout you can try adding all images ina column
hi i want someone to help me for this problem in flutter ,I will put the picture to understand

thanks
Wrap your page in a Listview() widget or a Single ChildScrollview
This means that your widget needs space more than the space that is available. You can either change the size of the widget, or make your page/widget scrollable, which will give it more vertical space. To do that, wrap your widget/page with a SingleChildScrollView widget.
I want to give a margin around the whole screen in Flutter. So I put my content inside a Column and put the Column inside a Container. So I gave a padding to the whole screen. But when a TextField is selected and the keyboard appears the bottom overflow. I can't give resizeToAvoidBottomPadding: false, because then the keyboard covers the TextField.
I can't use SingleChildScrollView or a ListView because then the placing of the children won't keep space between.
It seems the only option is to remove the Container and set a padding to each child of the Column.
Is there a better option for this ?
