Introduction to flutter

Flutter is an open-source UI software development kit created by Google. It is used to develop applications for Android, iOS, Windows, Mac, Linux, and the web.
The major components of Flutter include:
  • Dart platform
  • Flutter engine
  • Foundation library
  • Design-specific widgets

A Hello, World program in Flutter looks like this:
import 'package:flutter/material.dart';
void main() => runApp(HelloWorldApp());
class HelloWorldApp extends StatelessWidget {
Widget build(BuildContext context) {
return MaterialApp(
title: 'Hello World App',
home: Scaffold(
appBar: AppBar(
title: Text('Hello World App'),
),
body: Center(
child: Text('Hello World'),
),
),
);
}
}

  Functions Functions let you package multiple related lines of code into a single body that you can summon to avoid repeating those lines of code throughout your Dart application: A function consists of a return type , a function name , a parameter list in parentheses, and then a function body enclosed in braces. The code you're turning into the function goes inside the braces. When you call the function, you pass in arguments that match the types of the parameters of the function. Write a new function in DartPad that will just check to see if a given string is banana. bool isBanana( String fruit) { return fruit == 'banana' ; } The function uses return to return a bool value determined by the argument passed to the function. This function will always return the same value for any given input. If a function does not need to return a value, you can set the return type to void , such as for the main function.   Optional Parameters If a parameter to a funct

Push Notifications are a sort of pop-up messaging medium that alerts app users to what's going on in the app. They are also an important way to amplify user engagement in your app. For example, say a user forgets about the app once they have installed it. Then you can use push notifications as a mechanism to regain and retain their interest. Push notifications also help drive traffic to your app. Firebase Cloud Messaging is a service offered by Firebase which lets you send these notifications to your users. You can set up various configurations to send different notifications to different audiences based on time and routine. Because of all these benefits, we are going to use it to send notifications to our Flutter app. Step 1: Create a Flutter Project First, we are going to create a flutter project. For that, we must have the Flutter SDK installed in our system. You can find simple steps for flutter installation in the official documenta
