flutter - Using nearest neighbour interpolation for flutter image

Question

How do I get flutter to resize my Image widgets using nearest neighbour interpolation if the size of the widget is not the same as the asset size?

class PlayContainer extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      color: Color.fromARGB(255, 0, 110, 255),
      child: SafeArea(
        child: Image(
          fit: BoxFit.contain,
          image: AssetImage("assets/knight.png")
        )
      )
    );
  }
}

This resizes the image correctly, but it is blurry due to the bilinear interpolation used to resize it.

Based on the source seems to be rather hard coded?

多亏了这个拉取请求，这现在可以在主分支中实现：

我添加了在图像上设置 filterQuality 的可能性。这是硬编码的。
先前硬编码的值被设置为默认参数。

某些图像在没有滤镜质量（如像素艺术）的情况下缩放时看起来更好。这就是我添加参数的原因。
