[Flutter 实战] 圆形头像

在此记录项目中所遇到问题及解决方案

正方形的图片能正常显示：

Container(
  width: 60.0,
  height: 60.0,
  decoration: BoxDecoration(
    shape: BoxShape.circle,
    image: DecorationImage(
        image: _AssetImage(url)
    ),
  ),
)

如果是长方形的图片，上面的代码会显示成“椭圆”
给DecorationImage加一个参数fit=BoxFit.cover就正常显示圆形

Container(
  width: 60.0,
  height: 60.0,
  decoration: BoxDecoration(
    shape: BoxShape.circle,
    image: DecorationImage(
        fit: BoxFit.cover,
        image: _AssetImage(url)
    ),
  ),
)
