android - the element type 'List<widget>' can't be assigned to the list type 'Widget'

Question

I am trying to add data using for loop in gridview but it is showing some error. Here is my code for component

return new GridView.count(
    crossAxisCount: 2,
    padding: const EdgeInsets.all(10.0),
    crossAxisSpacing: 10.0,
    mainAxisSpacing: 10.0,
    children: <Widget>[getList()],
);

getList() code

List<Widget> getList() {
  List<Widget> childs = [];
  for (var i = 0; i < 10; i++) {
    childs.add(new ListItem('abcd ' + $i));
  }
  return childs;
}

But it is showing compile time error.

Answer 1

Here you are wrapping a list as list

children: <Widget>[getList()],

This should rather be

children: getList(),
