颤振：扩展小部件内的 ListView 在我的颤动应用程序中没有滚动

Question

我只想滚动我的列表项。 但它不工作。 如果我使用 SingleChildScrollView wrap Column 小部件，那么它会滚动，但只有当我单击列项而不是 listTile 项时才会滚动。

这是我的输出 我的预期输出是https://prnt.sc/URbiBkWLuXRZ这是我的代码

SafeArea(
    child: Column(
      children: [
        Expanded(flex: 2, child: customAdminDashboard()),
        Expanded(
            flex: 3,
            child: Column(
              children: [
                const Center(
                    child: Text(

                )),
                Padding(
                  padding: const EdgeInsets.only(
                      left: 20, right: 20, top: 2, bottom: 2),

                      Text(

                              fontSize: 18, color: Color(0xff925093))),
                    ],
                  ),
                ),
                StreamBuilder<QuerySnapshot>(
                  stream: FirebaseFirestore.instance
                      .collection("User-data")
                      .snapshots(),
                  builder: (BuildContext context,
                      AsyncSnapshot<QuerySnapshot> snapshot) {
                    if (snapshot.hasError) {
                      return Text('Something went wrong');
                    }

                    if (snapshot.connectionState ==
                        ConnectionState.waiting) {
                      return Text("Loading");
                    }

                    return ListView.builder(
                        shrinkWrap: true,
                        physics: AlwaysScrollableScrollPhysics(),
                        scrollDirection: Axis.vertical,
                        itemCount: snapshot.data!.docs.length,
                        itemBuilder: (_, index) {
                          DocumentSnapshot _DocumentSnapshot =
                              snapshot.data!.docs[index];
                          return ListTile(
                            leading: Text(_DocumentSnapshot['Name']),
                            trailing: Text(
                                _DocumentSnapshot['Balance'].toString()),
                          );
                        });
                  },
                )
              ],
            ))
      ],
    ),
  ),

我只想滚动我的 listTile 项目

ListView.builder(
                        shrinkWrap: true,
                        physics: AlwaysScrollableScrollPhysics(),
                        scrollDirection: Axis.vertical,
                        itemCount: snapshot.data!.docs.length,
                        itemBuilder: (_, index) {
                          DocumentSnapshot _DocumentSnapshot =
                              snapshot.data!.docs[index];
                          return ListTile(
                            leading: Text(_DocumentSnapshot['Name']),
                            trailing: Text(
                                _DocumentSnapshot['Balance'].toString()),
                          );
                        })
