Flutter Image bigger than container

问题

如何使图像在旋转并超出其容器时不显示在容器外部?
我还希望,如果图像处于正常位置并且大于其容器,它将被截断显示。
顺便问一下,图标可以采用相同的处理吗?

这是我的代码:

class CardList extends StatelessWidget {
  const CardList({
    Key? key,
    required this.text,
    required this.subText,
    required this.trailing,
  }) : super(key: key);

  final String text;
  final String subText;
  final Widget trailing;

  @override
  Widget build(BuildContext context) {
    GlobalKey _container = GlobalKey();
    return Card(
      shape: RoundedRectangleBorder(
        borderRadius: BorderRadius.circular(8),
      ),
      elevation: 0,
      color: Theme.of(context).colorScheme.surfaceVariant,
      margin: EdgeInsets.symmetric(horizontal: 0.5.w, vertical: 0.5.h),
      child: Row(
        children: [
          Container(
            padding: EdgeInsets.only(left: 10.w),
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              children: [
                AutoSizeText(text,
                    maxLines: 1,
                    style: Theme.of(context).textTheme.bodyText1),
                subText.isNotEmpty
                    ? AutoSizeText(
                        subText,
                        maxLines: 1,
                        style: Theme.of(context)
                            .textTheme
                            .subtitle1!
                            .copyWith(
                                color: Theme.of(context)
                                    .colorScheme
                                    .onSurfaceVariant,
                                fontWeight: FontWeight.w500),
                      )
                    : const SizedBox(
                        height: 0,
                      ),
              ],
            ),
          ),
          Container(
            color: Colors.blue,
            height: 100,
            child: Transform.translate(
              offset: Offset(0.0, 15.0),
              child: Transform.rotate(
                angle: -3.14 / 12.0,
                child: Image.asset(
                  'assets/images/map.png',
                  height: 300,
                ),
              ),
            ),
          ),
        ],
      ),
    );
  }
}

希望这对您有所帮助。

How can I make it so that if an image that is rotated and goes outside of its container does not show outside of it?
I would also like that if the image is in a normal position and if it is larger than its container, it will be shown cut off.
By the way, can I do the same treatment with the icons?

Here is my code

class CardList extends StatelessWidget {
  const CardList({
    Key? key,
    required this.text,
    required this.subText,
    required this.trailing,
  }) : super(key: key);

  final String text;
  final String subText;
  final Widget trailing;

  @override
  Widget build(BuildContext context) {
    GlobalKey _container = GlobalKey();
    return Card(
            shape: RoundedRectangleBorder(
              borderRadius: BorderRadius.circular(8),
            ),
            elevation: 0,
            color: Theme.of(context).colorScheme.surfaceVariant,
            margin: EdgeInsets.symmetric(horizontal: 0.5.w, vertical: 0.5.h),
            child: Row(
              children: [
                Container(

通过使用容器的 clipBehavior 并将其设置为 antiAlias,您可以确保子组件 child 永远不会超出其父容器,如下所示:

Container(
  clipBehavior: Clip.antiAlias, // 添加这一行
  decoration: BoxDecoration( // 添加这一行
    color: Colors.blue,
  ),
  height: 100,
  child: Transform.translate(
    offset: Offset(0.0, 15.0),
    child: Transform.rotate(
      angle: -3.14 / 12.0,
      child: Image.asset(
        'assets/images/map.png',
        height: 300,
      ),
    ),
  ),
)
英文:

By using Container's clipBehavior and set it to antiAlias you can make sure the child widget never appear outside of its parent, like this:

Container(
    clipBehavior: Clip.antiAlias, // add this
    decoration: BoxDecoration(// add this
        color: Colors.blue,
    ),
    height: 100,
    child: Transform.translate(
        offset: Offset(0.0, 15.0),
        child: Transform.rotate(
            angle: -3.14 / 12.0,
            child: Image.asset(
              'assets/images/map.png',
              height: 300,
            ))),
  ),

尝试以下代码,希望对您有所帮助,参考ClipRRect,只需将我的图像更换为您的图像。

FittedBox(
  child: ClipRRect(
    borderRadius: BorderRadius.circular(10.0),
    child: Container(
      constraints: BoxConstraints.tight(const Size(100, 100)),
      color: Colors.blue,
      child: Transform.translate(
        offset: const Offset(0.0, 15.0),
        child: Transform.rotate(
          angle: -3.14 / 12.0,
          child: const FlutterLogo(size: 300),
        ),
      ),
    ),
  ),
)

结果-> Flutter图像大于容器

英文:

Try below code hope its help to you, refer ClipRRect, just change my image with your image

 FittedBox(
          child: ClipRRect(
             borderRadius: BorderRadius.circular(10.0),
            child: Container(
              constraints: BoxConstraints.tight(const Size(100, 100)),
              color: Colors.blue,
              child: Transform.translate(
                offset: const Offset(0.0, 15.0),
                child: Transform.rotate(
                  angle: -3.14 / 12.0,
                  child: const FlutterLogo(size: 300),
                ),
              ),
            ),
          ),
        ),

Result-> Flutter图像大于容器

使用ClipRRect小部件将解决此问题。

如果将图像包装在旋转位置的ClipRRect小部件中,它将自动裁剪外部边缘。

ClipRRect(child: Image.network('your image'))

此外,在容器内的正常图像位置,如果角被圆角化而图像没有,您需要将图像放入ClipRRect小部件中,并使用borderRadius选项将图像圆角化以匹配容器的半径。

Container(
    decoration: BoxDecoration(borderRadius: BorderRadius.circular(5)),
    child: ClipRRect(
        borderRadius: BorderRadius.circular(5),
        child: Image.network('Your Image')
    )
)
英文:

Using ClipRRect Widget will solve that.

If you wrap your image inside a ClipRRect Widget in a rotation position, it will automatically cut the outward edges.

ClipRRect(child: Image.network('your image'))

Also, in a normal image position inside a container, if the corners are rounded and the image is not, you need to put your image inside a ClipRRect widget, and borderRadius option allows you to round your image to match the container radius.

Container(
    decoration: BoxDecoration(borderRadius: BorderRadius.circular(5)),
    child: ClipRRect(
        borderRadius: BorderRadius.circular(5),
        child: Image.network('Your Image')
    )
)
