In Flutter web, there are limitless possibilities of what sizes may be forced upon the app by resizing the browser. For example, my sign in with Apple and sign in with Google buttons from the flutter_signin_button package overflow when the browser is shrunk too small:
In a case where the window is shrunk unreasonably small, is there a way that I can suppress the overflow message? Or is there a release version of Flutter web that will not have these?
Wrap your widget into the scroll view. This is the easiest way to resolve the issue. Provide the fixed constraints for the both button and wrap into the scrollview with Horizontal scroll direction. If the screen size comes under the constraints, it will be the scrollable.
Use MediaQuery.
For width - MediaQuery.of(context).size.width;
For height - MediaQuery.of(context).size.height;
For size - MediaQuery.of(context).size
if(MediaQuery.of(context).size.width < 200px)
{
return someWidget
}

I'm working on a flutter project but having problem to make the widgets and texts to fit different phone screens. Tried looking for answers on youtube but I could not get any. Your help is appreciated. Thanks.rt
Here are some resources for your need.
For responsive layout,

https://pub.dev/packages/sizer (responsive layout plugin)
For responsive font,
https://pub.dev/packages/auto_size_text ( best option if you wanna resize font automatically based on parent widget's size )
For responsive widget,
Consider using Flexible, Expanded, MediaQuery.of(context).size.width, MediaQuery.of(context).size.height for widgets' dimensions instead of fixed sizes.
Use FittedBox, LayoutBuilder.
Have fun!!
I'd like to add a custom showMore widget if the skills widget which has a dynamic size(width) exceeds the screen width. On clicking the showMore widget it should show all the skills in a wrap .else show less.
In flutter
Constraints go down and sizes go up
See this documentation.
Flutter uses a single pass algorithm to render your application. This is a technical choice to ensure performance but it comes with limitations.
One of them is that, when you are building the widget tree, you only have access to the constraints of the parent, and not any size of any widget (since they are not rendered yet).
So a short answer to your question is:
No, you cannot do what you are trying to do (displaying something if some widgets are not fitting on the screen) since you don't have access to any sizes in the build method.
An alternative solution would be to use Wrap to wrap your chips or use a ListView on the horizontal axis to make the list of chips horizontally scrollable.
Anyway, if you really want to do this, you can hardcode the sizes of your chip and access the device size with MediaQuery.of(context).size or by using the LayoutBuilder and using contraints.maxWidth as the parent's width. Then you can check whether or not numberOfChips * chipSize <= maxWidth. But I wouldn't recommend it as the design wouldn't be responsive:
All the chips will have the same size, so you'll end up with a big chip for "c" and maybe a long name like "python" won't fit in and you'll end up with overflow issues.
What if the user changes the font size of his device? You will also end up with overflow issues.
So I am creating a new flutter widget and I am unable to understand how my app looks because of the space on top of the screen in my emulator,
As you can see there is a shaded area on top and my widgets are under it, is there any way to remove it?
Use Safe Area.
SafeArea is basically a glorified Padding widget. If you wrap another widget with SafeArea, it adds any necessary padding needed to keep your widget from being blocked by the system status bar, notches, holes, rounded corners, and other "creative" features by manufacturers.
Check this link for more.
Wrap your code with the SafeArea.

I have no idea to figure out this problem in flutter. I want to know the size without app bar size and tab bar size(up).
I use variable "vertical_size" as
var vertical_size = (MediaQuery.of(context).size.height -
AppBar().preferredSize.height -
MediaQuery.of(context).padding.top);
but I didn't figure out the tab bar size. It's mean there are oversized in Iphone. (Android is okay in now...)
Do you have any idea to measure tabbar height using Mediaquery? Or is there any idea to measure the actual using area?
You can always figure out the free space in any place you want in your layout with LayoutBuilder
In case of full usable screen height, you can use MediaQuery, but aparat from appbar's height and top padding, remember about bottom padding. You need to substract it as well
Hi and welcome to StackOverflow.
It's not oversized in iOS. What happens is that the AppBar will have in consideration the safe area, hence, its heigh will be bigger/smaller based on the device it is running on.
If you want to get the height of the screen without the AppBar heigh, just do it as the following:
Widget build() {
AppBar appBar = AppBar();
double vertical_size = MediaQuery.of(context).size.height - appBar.preferredSize.height;
return Scaffold(
appBar: appBar,
body: // your widget
);
}
The AppBar's height will have in consideration the device's status bar and so on, so there's no need to remove the inset padding manually.
I'm new with Widget development..I managed to built a widget, which could not be resized..I want it to be like - users manage to resize it according to themselves...Can someone tell me on how to make it possible?
Thanks friends.
The "android:resizeMode" tag in AppWidgetProviderInfo specifies whether a user can resize the widget vertically, horizontally, both, or neither.
The documentation can be found here:
http://developer.android.com/guide/topics/appwidgets/index.html#MetaData
In AppWidgetProviderInfo.xml
android:resizeMode="horizontal|vertical"
//for resizing horizontal and vertical resizing of widget
or
android:resizeMode="none"
//for disabling resize of widget
