}自定义裁剪区域二 class ClipperOvalPath extends CustomClipperRect {overrideRect getClip(Size size) {return Rect.fromLTRB(0, 0, size.width - 50.w, size.height - 100.w);}overridebool shouldReclip(CustomClipperRect oldClipper) {return false;}
} 自定义裁剪区域三 class ClipperOvalPath extends CustomClipperRect {overrideRect getClip(Size size) {return Rect.fromLTRB(0, 0, size.width - 50.w, size.height - 200.w);}overridebool shouldReclip(CustomClipperRect oldClipper) {return false;}
} ClipRRect 将子组件剪裁为圆角矩形 纯色背景裁剪为圆角矩形 ClipRRect(borderRadius: BorderRadius.circular(50.w),child: Container(width: 300.w,height: 300.w,decoration: const BoxDecoration(color: Colors.red),),) 将图片裁剪为圆角矩形 ClipRRect(clipper: ClipperOvalPath(),child: Image.asset(assets/demo/message.png,)), class ClipperOvalPath extends CustomClipperRRect {overrideRRect getClip(Size size) {return RRect.fromLTRBR(0, 0, size.width-100.w, size.height-140.w,Radius.circular(20.w));}overridebool shouldReclip(covariant CustomClipperRRect oldClipper) {return true;}
} 自定义裁剪区域导致裁剪图片为圆角矩形失败 class ClipperOvalPath extends CustomClipperRRect {overrideRRect getClip(Size size) {return RRect.fromLTRBR(0, 0, size.width-100.w, size.height-80.w,Radius.circular(20.w));}overridebool shouldReclip(covariant CustomClipperRRect oldClipper) {return true;}
} ClipRect 默认剪裁掉子组件布局空间之外的绘制内容溢出部分剪裁 Align(alignment: Alignment.topLeft,widthFactor: .5, //宽度设为原来宽度一半另一半会溢出child: Image.asset(assets/demo/message.png),),ClipRect(//将溢出部分剪裁child: Align(alignment: Alignment.topLeft,widthFactor: .5,//宽度设为原来宽度一半child: Image.asset(assets/demo/message.png),),), ClipPath 按照自定义的路径剪裁 设置了剪切的区域 Image.asset(assets/demo/message.png),DecoratedBox(decoration: const BoxDecoration(color: Colors.red),child: ClipRect(clipper: MyClipper(), //使用自定义的clipperchild: Image.asset(assets/demo/message.png)),) class MyClipper extends CustomClipperRect {overrideRect getClip(Size size) const Rect.fromLTWH(10.0, 15.0, 100.0, 200.0);overridebool shouldReclip(CustomClipperRect oldClipper) false;
