                                category: widget.categoryPage,

                            ),
                          );
                        },
                        child: Text("글쓰기"))
                  ],
                ),
                snapshot.hasData
                    ? Column(

                          ListView.builder(
                            physics: NeverScrollableScrollPhysics(),
                            shrinkWrap: true,

                        ],
                      )
                    : Center(
                        child: CircularProgressIndicator(),
                      )
              ],
            ),
          ),
        );
      },
    );

Answer 1

I found a solution but there is another problem. The problem is that I have SingleChildScrollView already in parent widget like shown below:

    return SingleChildScrollView( //have SingleChildScrollView already
      child: Column(
        children: [
          RefreshIndicator(
              child: SingleChildScrollView(
                child: ListView.builder(
                  itemBuilder: (BuildContext context, int index) {
                    return ListViewItem();
                  },
                ),
              ),
              onRefresh: () async {}),
        ],
      ),
    );

So I did it like shown below:

    @override
      Widget build(BuildContext context) {
        return RefreshIndicator(
          child: SingleChildScrollView(
            child: Column(
              children: [
                ListView.builder(
                  itemBuilder: (BuildContext context, int index) {
                    return ListViewItem();
                  },
                ),
              ],
            ),
          ),
          onRefresh: () async {},
        );
