使用FadeinImage包裹ExtendedImage.network 后，只能左右滑动，无法放大缩小以及双击等，请问有什么解决办法么？

```dart Widget image = FadeInImage( placeholder: const AssetImage('assets/black_bg_placeholder.jpg'), image: ExtendedImage.network( item, fit: BoxFit.contain, enableSlideOutPage: true, mode: ExtendedImageMode.gesture, imageCacheName: 'CropImage', //layoutInsets: EdgeInsets.all(20), initGestureConfigHandler: (ExtendedImageState state) { double? initialScale = 1.0; if (state.extendedImageInfo != null) { initialScale = initScale( size: size, initialScale: initialScale, imageSize: Size(state.extendedImageInfo!.image.width.toDouble(), state.extendedImageInfo!.image.height.toDouble())); } return GestureConfig( inPageView: true, initialScale: initialScale!, maxScale: max(initialScale, 5.0), animationMaxScale: max(initialScale, 5.0), initialAlignment: InitialAlignment.center, //you can cache gesture state even though page view page change. //remember call clearGestureDetailsCache() method at the right time.(for example,this page dispose) cacheGesture: false, ); }, onDoubleTap: (ExtendedImageGestureState state) { ///you can use define pointerDownPosition as you can, ///default value is double tap pointer down postion. final Offset? pointerDownPosition = state.pointerDownPosition; final double? begin = state.gestureDetails!.totalScale; double end; //remove old _doubleClickAnimation?.removeListener(_doubleClickAnimationListener); //stop pre _doubleClickAnimationController.stop(); //reset to use _doubleClickAnimationController.reset(); if (begin == doubleTapScales[0]) { end = doubleTapScales[1]; } else { end = doubleTapScales[0]; } _doubleClickAnimationListener = () { //print(_animation.value); state.handleDoubleTap( scale: _doubleClickAnimation!.value, doubleTapPosition: pointerDownPosition); }; _doubleClickAnimation = _doubleClickAnimationController.drive(Tween(begin: begin, end: end)); _doubleClickAnimation!.addListener(_doubleClickAnimationListener); _doubleClickAnimationController.forward(); }, loadStateChanged: (ExtendedImageState state) { if (state.extendedImageLoadState == LoadState.completed) { final Rect imageDRect = getDestinationRect( rect: Offset.zero & size, inputSize: Size( state.extendedImageInfo!.image.width.toDouble(), state.extendedImageInfo!.image.height.toDouble(), ), fit: BoxFit.contain, ); detailKeys[index] ??= ImageDetailInfo( imageDRect: imageDRect, pageSize: size, imageInfo: state.extendedImageInfo!, ); final ImageDetailInfo? imageDetailInfo = detailKeys[index]; return StreamBuilder( builder: (BuildContext context, AsyncSnapshot data) { return ExtendedImageGesture( state, canScaleImage: (_) => _imageDetailY == 0, imageBuilder: (Widget image) { return Stack( children: [ Positioned.fill( child: image, top: _imageDetailY, bottom: -_imageDetailY, ), Positioned( left: 0.0, right: 0.0, top: imageDetailInfo!.imageBottom + _imageDetailY, child: Opacity( opacity: _imageDetailY == 0 ? 0 : min( 1, _imageDetailY.abs() / (imageDetailInfo.maxImageDetailY / 4.0), ), child: ImageDetail( imageDetailInfo, index, widget.tuChongItem, ), ), ), ], ); }, ); }, initialData: _imageDetailY, stream: rebuildDetail.stream, ); } return null; }, ).image); ```
