在此記錄項(xiàng)目中所遇到問題及解決方案

正方形的圖片能正常顯示：

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

如果是長方形的圖片，上面的代碼會(huì)顯示成“橢圓”
給DecorationImage加一個(gè)參數(shù)fit=BoxFit.cover就正常顯示圓形

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