flutter ImageAsset图像延伸到BoxDecoration容器外部

Question

我在BoxDecoration中有一个Image，当我从CachedNetworkImageProvider获取图像时，它可以工作，但是当我从Assetimage获取图像时，该图像没有被裁剪到盒子的大小。这两个图像源都显示在ListTile中。 来自AssetImage的代码：

      return Container(
      width: widget.width, 
      height: widget.heigth,
      decoration: BoxDecoration(
      shape: BoxShape.circle,
      border: Border.all(color:widget.colour, width:3),
      image: DecorationImage(
      fit: BoxFit.cover,
      image: AssetImage(url)
       )....

来自CachedNetworkImageProvider的代码：

return Container(
width: widget.width, 
height: widget.heigth,
decoration: BoxDecoration(
  shape: BoxShape.circle,
  border: Border.all(color:widget.colour, width:3),
  image: DecorationImage(
    fit: BoxFit.cover,
    image: CachedNetworkImageProvider(widget.location.imageURLs[widget.index])...

Answer 1

不是将其作为boxDecoration.image的属性，而是尝试将其设置为child？

return Container(
child: DecorationImage(
fit: BoxFit.cover,
image: AssetImage(url)
)....
width: widget.width,
height: widget.heigth,
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(color:widget.colour, width:3)),

Answer 3

使用以下示例

decoration: BoxDecoration(

                image: DecorationImage(
                  alignment: Alignment.center,
                  matchTextDirection: true,
                  repeat: ImageRepeat.noRepeat,
                  image: AssetImage("assets/images/bed.jpg"),
                ))
