Why Expanded widget can not add a child which is Text in Dart?

Question

When I add a Expanded widget whose child is Text into a list,Android Studio throw a error message like this: Error: The argument type 'Expanded' can't be assigned to the parameter type 'Text'.

final List<Text> words = [];
words.add(Expanded(child: Text('hello')));

enter image description here

Answer 1

Expanded is a widget that can be used with(inside) Row, Column and Flex. You can't add it to a list of type Text, just remove it.

Answer 2

Try this:

final List<Text> words = [];
words.add(Text('hello'));
