flutter - 如何更改 OutlinedButton 的边框颜色

Question

我想更改 OutlinedButton 的边框颜色。你能告诉我怎么做吗？

OutlinedButton(
              onPressed: null,
              style: ButtonStyle(
                shape: MaterialStateProperty.all(
                  RoundedRectangleBorder(
                    borderRadius: BorderRadius.circular(25.0),
                  ),
                ),
              ),
              child: const Text("Kontynuuj jako gość",
                  style: TextStyle(fontSize: 20, color: Color(0xffffffff)),
                  textAlign: TextAlign.center),
            ),

我试过Cannot change border color in OutlinedButton但它不起作用。

指定 ButtonStyle 的侧面参数

ButtonStyle(
  side: MaterialStateProperty.all(BorderSide(color: Colors.deepOrange)),
  shape: MaterialStateProperty.all(
    RoundedRectangleBorder(
      side: BorderSide(color: Colors.deepOrange),
      borderRadius: BorderRadius.circular(25.0),
    ),
  ),
)
