无法将 XFile 类型的值分配给 List<XFile>

Question

我想将相机拍摄的图像保存到列表以在 GridView 中显示多个图像。但我不知道该怎么做 it.I 想将 XFile 列表添加到变量 _imagesList

List<XFile> _imagesList=[];
void selectCamera(ImageSource imagesource,BuildContext cntxt) async {
    
    File cameraImages = await _picker.pickImage(source: imagesource); //error
    if(cameraImages!=null){
      _imagesList.addAll(cameraImages);

    }

    for(var img in _imagesList){
      final appDir = await getApplicationDocumentsDirectory();  
    final fileName = basename(img.path);    
    final savedImage = await File(img.path).copy('${appDir.path}/$fileName');
    }
    
  }
