将flutter_just_toast添加到Pubspecs中的依赖项中。yaml文件。

依赖关系:

flutter_just_toast: ^1.0.1

接下来将包导入到你的类中:

import 'package:flutter_just_toast/flutter_just_toast.dart';

用一条消息实现Toast:

Toast.show(message: "Your toast message",
    duration: Delay.SHORT,
    textColor: Colors.black);

你可以直接使用小吃店的元素

 ScaffoldMessenger.of(context).showSnackBar(
      SnackBar(
        content: Text("Successfully!"),
        behavior: SnackBarBehavior.floating,
        margin: EdgeInsets.all(20),
          shape: StadiumBorder(),
        action: SnackBarAction(
          label: 'Dismiss',
          disabledTextColor: Colors.white,
          textColor: Colors.blue,
          onPressed: () {
            //Do whatever you want
          },
        ),
      ),
    );

你可以使用FlutterToast之类的软件。

导入库:

fluttertoast: ^2.1.4

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,
);

就是这样……

颤振里没有任何烤面包的小部件。你可以去这个插件。

用例:

Fluttertoast.showToast(
    msg: "My toast message",
    textColor: Colors.white,
    toastLength: Toast.LENGTH_SHORT,
    timeInSecForIos: 1,
    gravity: ToastGravity.BOTTOM,
    backgroundColor: Colors.indigo,);

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);

要显示Toast消息，您可以使用FlutterToast插件。要使用这个插件，你必须:

将此依赖项添加到您的pubspec中。Yaml文件:fluttertoast: ^8.0.8 要获取包，必须运行以下命令:$ flutter packages get 导入包:导入'package:fluttertoast/fluttertoast.dart';

像这样使用它:

Fluttertoast.showToast(
    msg: "your message",
    toastLength: Toast.LENGTH_SHORT,
    gravity: ToastGravity.BOTTOM // Also possible "TOP" and "CENTER"
    backgroundColor: "#e74c3c",
    textColor: '#ffffff');
