fluttertoast: ^ 3.1.3

import 'package:fluttertoast/fluttertoast.dart';

Fluttertoast.showToast(
        msg: "This is Center Short Toast",
        toastLength: Toast.LENGTH_SHORT,
        gravity: ToastGravity.CENTER,
        timeInSecForIos: 1,
        backgroundColor: Colors.red,
        textColor: Colors.white,
        fontSize: 16.0
    );

您可以使用此链接在Flutter中显示Toast。

可以这样使用:

void method1(){

    Fluttertoast.showToast(
        msg: "This is Add Button",
        toastLength: Toast.LENGTH_SHORT,
        gravity: ToastGravity.CENTER,
        timeInSecForIosWeb: 1,
        backgroundColor: Colors.blueGrey,
        textColor: Colors.white,
        fontSize: 14.0
    );
}

用这个:

Fluttertoast.showToast(
    msg: "This is a Toast message",
    toastLength: Toast.LENGTH_SHORT,
    gravity: ToastGravity.CENTER,
    timeInSecForIos: 1
);

在这里买颤振吐司包

将这个包添加到文件pubspec.yaml中的项目依赖项中。

然后当你想要吐司显示时，就像点击一个按钮:

Toast.show("Toast plugin app", context, duration: Toast.LENGTH_SHORT, gravity: Toast.BOTTOM);

我想提供一个替代解决方案，以使用包刷新条。

正如包中所说:如果在通知用户时需要更多自定义，请使用此包。对于Android开发人员来说，它可以替代吐司和零食条。

使用flushbar的另一个建议是如何在Flutter的navigator.pop(context)之后显示小吃条?

你也可以设置flushbarPosition为TOP或BOTTOM:

    Flushbar(
      title: "Hey Ninja",
      message: "Lorem Ipsum is simply dummy text of the printing and typesetting industry",
      flushbarPosition: FlushbarPosition.TOP,
      flushbarStyle: FlushbarStyle.FLOATING,
      reverseAnimationCurve: Curves.decelerate,
      forwardAnimationCurve: Curves.elasticOut,
      backgroundColor: Colors.red,
      boxShadows: [BoxShadow(color: Colors.blue[800], offset: Offset(0.0, 2.0), blurRadius: 3.0)],
      backgroundGradient: LinearGradient(colors: [Colors.blueGrey, Colors.black]),
      isDismissible: false,
      duration: Duration(seconds: 4),
      icon: Icon(
        Icons.check,
        color: Colors.greenAccent,
      ),
      mainButton: FlatButton(
        onPressed: () {},
        child: Text(
          "CLAP",
          style: TextStyle(color: Colors.amber),
        ),
      ),
      showProgressIndicator: true,
      progressIndicatorBackgroundColor: Colors.blueGrey,
      titleText: Text(
        "Hello Hero",
        style: TextStyle(
            fontWeight: FontWeight.bold, fontSize: 20.0, color: Colors.yellow[600], fontFamily: "ShadowsIntoLightTwo"),
      ),
      messageText: Text(
        "You killed that giant monster in the city. Congratulations!",
        style: TextStyle(fontSize: 18.0, color: Colors.green, fontFamily: "ShadowsIntoLightTwo"),
      ),
    )..show(context);

导入库fluttertoast: 3.1.3

像下面这样使用它:

Fluttertoast.showToast(
    msg: "Hello, World!",
    textColor: Colors.white,
    toastLength: Toast.LENGTH_SHORT,
    timeInSecForIos: 1,
    gravity: ToastGravity.BOTTOM,
    backgroundColor: Colors.indigo,
);
