I want to add a color in my TextButton and the error-CodePudding

When I add a color to my "TextButton" an error pops up.

The named parameter 'color' isn't defined. Try correcting the name to an existing named parameter's name, or defining a named parameter with the name 'color'.

How do I solve? Line of code below

Row( children: <Widget>[ TextButton( onPressed: () {},
child: Text('Entrar'), color: Color(0xff7540ee).withOpacity(.2), ),

CodePudding user response：

Paste this code it will work.

Row(
     children: <Widget>[
            TextButton(
              onPressed: () {},
              child: Text('Entrar'),
              style: ButtonStyle(
                foregroundColor: MaterialStateProperty.all(
                  Color(0xff7540ee).withOpacity(.2),
                ),
              ),
            ),
          ],
        ),

Replace this code

child: Text('Entrar'), color: Color(0xff7540ee).withOpacity(.2),

to this

child: Text('Entrar', style: TextStyle(Color(0xff7540ee).withOpacity(.2)),
