I just had the same problem and it's happen because of the "selecteds" property. So just pass it like this and It'll solve your problem.
selecteds: []

This code only work with mobile UI which is rendered by mobileList at responsive_datatable.dart:156. it will crash when it render with desktopList at responsive_datatable.dart:312. The logic is not right and the parameters requirement is not match with the logic inside.
Some parameters aren't check if they are null when widget render with desktopList at responsive_datatable.dart:312 @danhdevelop.
So "expanded" property make "Unexpected null value" like "selecteds" too. So if you want to use this widget you must, create an array with same number of values that source. I used this to solve it.
expanded: List.filled(_sublist.length, false)
Hello,
Am new to Flutter Web and Dart. I am trying to use this package in a test web app. I have followed the example but I keep getting the Unexpected null value error.
I am using: responsive_table: ^0.2.0+2 Flutter (Channel stable, 2.10.4, on Microsoft Windows [Version 10.0.17763.2746], locale en-US)
The terminal output is:
