What is Toast Message?

Some Times Toast Messages are also called as Toast Notification.

It’s a small message that pops up at the bottom of the device screen and immediately disappears on its own after a delay of few seconds,

This are mostly used to show a feedback on the operation that is preformed by the user.

So, Let’s Begin Implementing FlutterToast Message into your project

Result of the Tutorial

Step 1 : Adding Flutter Toast Dependencies in project

To get access to Futter Toast you need to add it’s Plugin into your Flutter Project

Open pubspec.yaml  and add the dependencies plugin

dependencies:
  flutter:
    sdk: flutter
  cupertino_icons: ^0.1.2
  fluttertoast: ^3.1.3    // add this line

Note :  This Plugin version might get updated so better be updated with latest version ( here )

Step 2 : Import the Fluttertoast dart package

Now, once you have added dependencies into you project now you can user the Flutter Toast plugin anywhere in your project to show the toast message

Open main.dart  and then at the top import the package

import 'package:fluttertoast/fluttertoast.dart';

Step 3 : How to use the Toast message widget in flutter

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

There are several properties that you can user to show the Toast message.

propertyDescription
msgString ( Required )
toastlengthToast.LENGTH_SHORT or Toast.LENGTH_LONG
gravityToastGravity.TOP or ToastGravity.CENTER or ToastGravity.BOTTOM
timeInSecforIosonly for Ios ( 1 sec or more )
backgroundColorColors.blue
textColorColors.red
fontSize16.0

And to Cancel all the Toast Calls then you can user

FlutterToast.cancel() : This will Immediately cancel all the request to show Message to user.

If you don’t want to user androidx then make user of older version of fluttertoast 2.211
