Flutter:如何修复轮廓按钮并为其添加边框和颜色？

Question

有人能告诉我为什么我的代码没有将边框设为蓝色，而是让它的宽度为 3.0 吗？

这是它的样子(L:我的应用程序，R:教程应用程序):

代码:

class CreateRoomButton extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return OutlinedButton(
      onPressed: () => print('Create Room'),
      style: ButtonStyle(
        shape: MaterialStateProperty.all<RoundedRectangleBorder>(
          RoundedRectangleBorder(
            side: BorderSide(
              color: Colors.blueAccent[100],
              width: 3.0,
            ),
            borderRadius: BorderRadius.circular(30.0),
          ),
        ),
      ),
      child: Row(
        children: [
          ShaderMask(
            shaderCallback: (rect) =>
                Palette.createRoomGradient.createShader(rect),
            child: Icon(
              Icons.video_call,
              color: Colors.white,
              size: 35.0,
            ),
          ),
          const SizedBox(width: 4.0),
          Text(
            'Create\nRoom',
            style: TextStyle(color: Colors.blueAccent[100]),
          ),
        ],
      ),
    );
  }
}

此外，我还必须在某处添加它(但由于 textColor 在 flutter 2.0 中已贬值，我不知道如何处理它...):

textColor: Palette.facebookblue,

谢谢!

只需将您的 OutlinedButton 更改为:

OutlinedButton(
    onPressed: () => print('Create Room'),
    style: OutlinedButton.styleFrom(
      shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(30.0),
      ),
      side: BorderSide(width: 3.0, color: Colors.blueAccent[100]),
    )
    child: yourChildWidget,
)
