                            scrollDirection: Axis.horizontal,
                            shrinkWrap: true,

                            // itemCount: 1,
                            itemBuilder: (context, index) {
                              return InkWell(
                                  child: Padding(
                                padding: EdgeInsets.only(

                            }),
                      ),

CodePudding user response：

In your code FileImage(keepImage[index - 1]). You are subtracting index with 1 which will result in -1. But accepted value in 0 or a value greater than 0. Change it to FileImage(keepImage[index]). Then it should work as expected.
