CodePudding user response：

You can add a shape parameter to your TextButton

TextButton(
      style: TextButton.styleFrom(
          backgroundColor: Colors.yellow,
          shape: const RoundedRectangleBorder(
              borderRadius: BorderRadius.all(Radius.zero))),
      child: const Text("BUtton"),
      onPressed: () {},
    )
