            Text.rich(
              TextSpan(
                text: 'Text: ',
                children: [
                  TextSpan(text: 'hello '),
                  TextSpan(text: 'world', style: TextStyle(color: Colors.red)),
                ],

              textScaleFactor: 1.5,
            ),
