我可以在Flutter中创建类似Toasts的东西吗?
只是一个很小的通知窗口,不直接面对用户,也不锁定或淡出它后面的视图。

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

您可以使用飘动吐司包装。为此,将其添加到pubspec中。Yaml文件如下:
dependencies:
fluttertoast: ^8.0.8
然后在需要吐司的.dart文件中导入这个包并编写代码。
例如,参考以下代码:
import 'package:flutter/material.dart';
import 'package:fluttertoast/fluttertoast.dart';
class ToastExample extends StatefulWidget {
@override
_ToastExampleState createState() {
return _ToastExampleState();
}
}
class _ToastExampleState extends State {
void showToast() {
Fluttertoast.showToast(
msg: 'This is flutterToast example', // Message
toastLength: Toast.LENGTH_SHORT, // toast length
gravity: ToastGravity.CENTER, // position
timeInSecForIos: 1, // duaration
backgroundColor: Colors.red, // background color
textColor: Colors.white // text color
);
}
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Toast Tutorial',
home: Scaffold(
appBar: AppBar(
title: Text('Toast Tutorial'),
),
body: Padding(
padding: EdgeInsets.all(15.0),
child: Center(
child: RaisedButton(
child: Text('Show Toast'),
onPressed: showToast,
),
),
)
),
);
}
}
void main() => runApp(ToastExample());
Importcupertino_icons: ^0.1.2并编写以下代码:
showToast(BuildContext context, String message) {
showDialog(
context: context,
builder: (BuildContext context) {
return CupertinoAlertDialog(
title: Text(
"Name of App",
),
content: Text(
message,
),
actions: [
CupertinoButton(
child: Text("OK"),
onPressed: () {
Navigator.of(context).pop();
},
)
],
);
},
);
});
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……
用这个:
Fluttertoast.showToast(
msg: "This is a Toast message",
toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIos: 1
);
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
},
),
),
);
