仿 掘金-我 效果

先看下效果：

拿到效果图先不要慌 （取出手机拍照发个朋友圈😊），整个列表每一行的布局基本一样，所以先写出一行的效果：

class _SettingItem extends StatelessWidget {
  const _SettingItem(
      {Key key, this.iconData, this.iconColor, this.title, this.suffix})
      : super(key: key);

  final IconData iconData;
  final Color iconColor;
  final String title;
  final Widget suffix;

  @override
  Widget build(BuildContext context) {
    return Container(
      height: 45,
      child: Row(
        children: <Widget>[
          SizedBox(
            width: 30,
          ),
          Icon(iconData,color: iconColor,),
          SizedBox(
            width: 30,
          ),
          Expanded(
            child: Text('$title'),
          ),
          suffix,
          SizedBox(
            width: 15,
          ),
        ],
      ),
    );
  }
}

消息中心和其他行最后的样式不一样，单独封装，带红色背景的组件：

class _NotificationsText extends StatelessWidget {
  final String text;

  const _NotificationsText({Key key, this.text}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Container(
      padding: EdgeInsets.symmetric(horizontal: 10),
      decoration: BoxDecoration(
          shape: BoxShape.rectangle,
          borderRadius: BorderRadius.all(Radius.circular(50)),
          color: Colors.red),
      child: Text(
        '$text',
        style: TextStyle(color: Colors.white),
      ),
    );
  }
}

灰色后缀组件：

class _Suffix extends StatelessWidget {
  final String text;

  const _Suffix({Key key, this.text}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Text(
      '$text',
      style: TextStyle(color: Colors.grey.withOpacity(.5)),
    );
  }
}

将这些封装好的组件组合起来：

class SettingDemo extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Column(
      children: <Widget>[
        _SettingItem(
          iconData: Icons.notifications,
          iconColor: Colors.blue,
          title: '消息中心',
          suffix: _NotificationsText(
            text: '2',
          ),
        ),
        Divider(),
        _SettingItem(
          iconData: Icons.thumb_up,
          iconColor: Colors.green,
          title: '我赞过的',
          suffix: _Suffix(
            text: '121篇',
          ),
        ),
        Divider(),
        _SettingItem(
          iconData: Icons.grade,
          iconColor: Colors.yellow,
          title: '收藏集',
          suffix: _Suffix(
            text: '2个',
          ),
        ),
        Divider(),
        _SettingItem(
          iconData: Icons.shopping_basket,
          iconColor: Colors.yellow,
          title: '已购小册',
          suffix: _Suffix(
            text: '100个',
          ),
        ),
        Divider(),
        _SettingItem(
          iconData: Icons.account_balance_wallet,
          iconColor: Colors.blue,
          title: '我的钱包',
          suffix: _Suffix(
            text: '10万',
          ),
        ),
        Divider(),
        _SettingItem(
          iconData: Icons.location_on,
          iconColor: Colors.grey,
          title: '阅读过的文章',
          suffix: _Suffix(
            text: '1034篇',
          ),
        ),
        Divider(),
        _SettingItem(
          iconData: Icons.local_offer,
          iconColor: Colors.grey,
          title: '标签管理',
          suffix: _Suffix(
            text: '27个',
          ),
        ),
      ],
    );
  }
}
