The element type 'Set<DetailsCard>' can't be assigned to the list type 'Widget'

Column(
          children: [
            Widget1(),
            Widget2(),
            Expanded(
              child: SingleChildScrollView(
                child: Container(
                  child: Column(
                    children: [
                              for(var i =0 ;i<categories.length;i++){
                                DetailsCard(catName: categories[i]);
                              }
                    ],
                  ),
                ),
              ),
            ),
          ],
        ) 

In the above code i want to add multiple widgets based on the items in the categories list . But when I try using the for loop i keep getting "The element type ‘Set’ can’t be assigned to the list type ‘Widget’." error.

>Solution :

use for statement inside of [...] like below:

Column(
          children: [
            Widget1(),
            Widget2(),
            Expanded(
              child: SingleChildScrollView(
                child: Container(
                  child: Column(
                    children: [
                              for(var i =0 ;i<categories.length;i++)
                                DetailsCard(catName: categories[i])
                    ],
                  ),
                ),
              ),
            ),
          ],
        ) 

do not add {} and ; in [...] statement, it is illegal
