Welcome to the world of Flutter! Today, we’re going to explore the Toast Library for Flutter. This handy library allows you to display short messages (toasts) in your Flutter applications with ease. Whether it’s an Android app, iOS, or even a web application, FlutterToast has you covered.

Getting Started with FlutterToast

First, let’s add the FlutterToast library to your project. Here’s a quick guide to set it up:

• Open your pubspec.yaml file.
• Add the following line to your dependencies:
• fluttertoast: ^8.2.8
• Import the package into your Dart file:
• import 'package:fluttertoast/fluttertoast.dart';

Types of Toasts: With and Without BuildContext

FlutterToast supports two types of toasts:

• Toast with No BuildContext:

  This type is easy to use and works on Android, iOS, and Web (using Toastify-JS).

  However, it offers limited features and no control over the UI.

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

• Toast with BuildContext:

  This type provides full control and works across all platforms. You can queue toasts, remove a specific toast, or clear the entire queue. To use this, your MaterialApp needs to be updated:

  
  MaterialApp(
      builder: FToastBuilder(),
      home: MyApp(),
      navigatorKey: navigatorKey,
  );
          

  Initialize it in your app like so:

  
  FToast fToast;
  
  @override
  void initState() {
      super.initState();
      fToast = FToast();
      fToast.init(context);
  }
          

Creating Custom Toasts

If you’re looking to customize your toast message, you can create a custom layout. For Android, you can do this by creating an XML layout file in the app/res/layout/ folder:

Troubleshooting

If you encounter any issues while using FlutterToast, consider the following troubleshooting tips:

• Ensure that you have the correct Flutter and Dart SDK version installed.
• Check your dependencies in pubspec.yaml for any typos.
• Make sure to call Fluttertoast.cancel() to clear existing toasts if necessary.
• If custom toasts are not appearing on Android 11 and above, remember that only *msg* and *toastLength* will be considered.
