我正在使用Flutter开发一个应用程序，一切都正常运行。但有一天当我尝试运行应用程序时，出现了以下错误：

我正在使用flutter_speed_dial: ^1.2.5包（https://pub.dev/packages/flutter_speed_dial）， 但是我在一些论坛中查看了一些内容，但我尚未解决此问题。
这是代码的一部分：
floatingActionButton: SpeedDial(
marginRight: 18,
marginBottom: 20,
child: Image.asset("Imagenes/Teams/team1_logo.png"),
closeManually: false,
curve: Curves.bounceIn,
overlayColor: Colors.black,
overlayOpacity: 0.5,
onOpen: () => print('OPENING DIAL'),
onClose: () => print('DIAL CLOSED'),
tooltip: 'Speed Dial',
heroTag: 'speed-dial-hero-tag',
backgroundColor: Colors.green,
foregroundColor: Colors.black,
elevation: 8.0,
shape: CircleBorder(),
children: [
SpeedDialChild(
child: FittedBox(
child: Image.asset(
"Imagenes/Teams/team2_logo.png",
width: 2,
height: 2,
alignment: Alignment.center,
)),
backgroundColor: Colors.red,
label: 'Vikingos',
labelStyle: TextStyle(fontSize: 18.0),
onTap: () {
/* // variables para mover el equipo principal al seleccionar uno del floating button
team_wait = team_selected;
team_selected = team_child1;
team_child1 = team_wait;
print(team_selected);
print(team_child1);*/
}),
SpeedDialChild(
child: FittedBox(
child: Image.asset(
"Imagenes/Teams/team3_logo.png",
width: 10,
height: 10,
alignment: Alignment.center,
)),
backgroundColor: Colors.blue,
label: 'Aguilas',
labelStyle: TextStyle(fontSize: 18.0),
onTap: () => print('SECOND CHILD'),
),
SpeedDialChild(
child: Image.asset("Imagenes/Teams/team4_logo.png"),
backgroundColor: Colors.yellow[700],
label: 'Inter',
labelStyle: TextStyle(fontSize: 18.0),
onTap: () => print('THIRD CHILD'),

],
),
