如何修复 Flutter 中的像素化图像

Question

我想创建一个圆形图像小部件，但它最终会像素化。

有了Image.network(url)，我得到以下信息：

而原来的样子是这样的：

这是相关代码：

class RoundedImage extends StatelessWidget {
  final String URL;
  final double size;
  final bool dynamicallySized;
  final double borderRadius;
  final bool onlyTopBorderRadius;

  const RoundedImage({
    @required this.size,
    @required this.url,
    this.dynamicallySized = false,
    this.borderRadius = 8.0,
    this.onlyTopBorderRadius = false,
  });

  @override
  Widget build(BuildContext context) {
    final newSize = dynamicallySized ? PaddingUtils.getPadding(context, padding: size) : size;
    return ClipRRect(
      borderRadius:
          onlyTopBorderRadius ? BorderRadius.vertical(top: Radius.circular(borderRadius)) : BorderRadius.circular(borderRadius),
      child: CachedNetworkImage(
        imageUrl: url,
        height: newSize,
        width: newSize,
        fit: BoxFit.cover,
      ),
    );
  }
}
