Why don’t you consider RichText.?

RichText(
        text: TextSpan(
          text: 'Click here to visit our website',
          style: TextStyle(
            color: Colors.black,
            fontSize: 18.0,
          ),
          children: <TextSpan>[
            TextSpan(
              text: ' قوانین و مقررات',
              style: TextStyle(
                color: Colors.blue,
                decoration: TextDecoration.underline,
              ),
              recognizer: TapGestureRecognizer()
                ..onTap = () {
                  Navigator.push(
                      context,
                      MaterialPageRoute(
                        builder: (context) => const LoginModal(),
                      ),
                    );
                },
            ),
          ],
        ),
      ),

or you can use GestureDetector

    GestureDetector(
   child: Text('Text here'),
onTap: () {
            print('Tapped');
          },
)

You can set tapTargetSize and padding to the TextButton as below:

TextButton(
  ...
  style: TextButton.styleFrom(
    tapTargetSize: MaterialTapTargetSize.shrinkWrap,
    padding: EdgeInsets.zero, // or other value
  ),
);
