I created a simple web app with Flutter. The app layout is divided in two vertically zones: on the left there is a small top-bottom menu, on the right there is the main content inside a DataTable.
I wrapped the DataTable inside a SingleChildScrollView and everything worked fine. The left side, on the other hand, keeps giving me a vertical overflow.
The tree on the left side is as follows:
Row(
children: [
//Left side menu
Flexible(
Container(
Column()
), //Container
), //Flexible
//Right side
Flexible(...),
],
), //Row
Obviously it is a very simplified version.
I've tried to insert a SingleChildScrollView in almost all places (Column, Container, Flexible), but it doesn't work and it always returns the error.
A RenderFlex overflowed by 174 pixels on the bottom.
Any solutions?
Thank you!
My approach would be to use MediaQuery
to get current height and width of the web window. Then spilt the available width in the ratio of 2:7 maybe? You can play around with the ratio.
Now, lets keep the body of Scaffold
to be Container
with width as MediaQuery.of(context).size.width
and height as ... .height
. Now Row
with childrens be 2 Expanded widgets with flex 2
and flex 7
respectively. Now we have to portion in the screen in the ratio 2:7.
On the left side, as you said, you need a menu, let it be
Expanded(
flex:2,
child: Column())
And on the other side be-
Expanded(
flex:7,
child: Container(
child: SingleChildScrollView() ///then add your stuff for scrolling purposes.
)
)
