我正在使用flutter_speed_dial：^ 1.2.5程序包（https://pub.dev/packages/flutter_speed_dial）和我当时在一些论坛上找东西，但还不能解决这个问题。

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'),
          ),
        ],
      ),

Answer 1

您还应该检查库的PR；）。 This one解决了该问题。您可以检查commits并更改自己的代码。或者也许要等待几天，几小时才能完成合并。

如果确实需要，可以派生该库，但现在只需注释引用该库的代码，直到合并修订为止

Answer 2

此错误通常是由过期（out-version）第三方程序包引起的，最简单的解决方案是：

转到puspec.yaml，然后删除所有运行“ flutter pub get的第三方程序包（记住您正在使用的程序包），然后转到终端执行“ flutter Clean”，然后添加所有具有最新版本的软件包都运行“ flutter pub get”。

如果问题仍然存在，请尝试删除导致该问题的唯一软件包。在我的情况下，curvedNavigationBar是有问题的，我删除了程序包，然后问题解决了。

Answer 3

我遇到了这种问题。更新了Flutter SDK之后，我的问题解决了。更新您的Flutter SDK，它可能会起作用。

Flutter错误：没有名为“ overflow”的命名参数
