Is there any way to re-render a widget outside Stateful class in flutter

Question

Iam working with data table, and i want to add remove action on every data rows. I use this as my reference code: Screen Data Source I insert a remove button as the element of the last cell, and use _dessert.remove(desert) to remove the row from the list. The row is already deleted, but the element stay in the table unless I refresh the page. Any solution for this?

Answer 1

If you can get BuildContext, you can use:

(context as Element).markNeedsBuild()

but it's not recommended!

Answer 2

Use setState. It will re-render the widgets.

setState(() { _myState = newValue; });
