Try below code. This will give multi-line where you can also control the text styling. Use Text instead of RichText if you do not want different style for all the lines.

             AppBar(
                title: RichText(
                  textAlign: TextAlign.center,
                  text: TextSpan(
                      text: "Developer Developer",
                      style: TextStyle(fontSize: 20),
                      children: [
                        TextSpan(
                          text: '\nTrip List',
                          style: TextStyle(
                            fontSize: 16,
                          ),
                        ),
                      ]
                  ),
                ),
                backgroundColor: MissionGPSTheme.themeBlueColor
            ),
