flutter - 如何更改 OutlinedButton 边框颜色？

Question

Flutter 小部件，我尝试使用 BorderSide(color : Colors.blue) 更改 OutlineButton 边框颜色。无论设置哪种颜色，OutlineButton 始终带有灰色边框，但宽度更改适用。如何更改 OutlineButton 边框线条颜色？

class OutlineButtonWidget extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return Center(
        child: OutlineButton(
            onPressed: null,
            borderSide: BorderSide(
                width: 5.0,
                color: Colors.blue,
                style: BorderStyle.solid,
            ),
            child: Text('outline button')
            ),
        ),
    );
  }
}

Answer 1

使用 style属性(property)

OutlinedButton(
  onPressed: () {},
  child: Text('Outlined button'),
  style: OutlinedButton.styleFrom(
    side: BorderSide(width: 5.0, color: Colors.blue),
  ),
)
