I’m making my project with flutter, and used ListTile Widget, and set icons in ListTile’s leading.

but It only locates in center.. I used Align, Center, Container decoration and so on.

problems

here’s the code

                  ListTile(
                    horizontalTitleGap: 10,
                    leading: Align(
                      alignment: Alignment.topCenter,
                      child: CircleAvatar(child: FaIcon(FontAwesomeIcons.dog, size:28, color: Colors.white), backgroundColor: Color(0xffB8CCA3)),
                    ),
                    title: Text(" ${messages[index].nickname}", textAlign: TextAlign.left, style: TextStyle(fontSize:14)),
                    subtitle: Align(
                      alignment: Alignment.centerLeft,
                      child: Container(
                          margin : const EdgeInsets.only(bottom:5),
                          padding: const EdgeInsets.fromLTRB(15, 5, 15, 5),
                          constraints: BoxConstraints(
                              maxWidth:320
                          ),
                          decoration: BoxDecoration(
                            color: Color(0xffe9ecef),
                            borderRadius: BorderRadius.circular(20),
                          ),
                          child: Text(messages[index].message, textAlign: TextAlign.left, style: TextStyle(fontSize: 17))
                      ),
                    )
                  );
