What is Flutter?

Flutter ek aisa tool hai jisse aap mobile apps bana sakte hain. Ye Google ne banaya hai. Iska sabse bada faayda ye hai ki aap ek baar code likh kar dono, Android aur iPhone ke liye, apps bana sakte hain.

Flutter mein aap Dart naam ki ek programming language ka use karte hain. Ye language aasani se seekhi ja sakti hai, khaaskar agar aapko pehle se Java ya JavaScript aati hai.

Flutter Ke Khaas Fayde

• Ek Code, Do Platforms: Ek hi code likh kar aap apni app ko Android aur iOS dono par chala sakte hain. Isse aapka time aur mehnat bachti hai.
• Fast Development with Hot Reload: Flutter mein "Hot Reload" naam ki feature hoti hai. Matlab, agar aap apne app ka code change karte hain, toh changes turant phone ke screen par dikhne lagte hain. Aapko app ko dubara start nahi karna padta. Ye feature development ko bahot tez aur mazedaar bana deta hai.
• Behtareen UI Banane Mein Madad: Flutter apne saath widgets ka ek bada collection lekar aata hai. Ye widgets app ke buttons, text, images wagaira banane ke liye building blocks ki tarah hain. Inki madad se aap khoobsurat aur smooth chalne wali apps aasani se bana sakte hain.
• Open Source Hai: Flutter bilkul free hai aur iska source code publicly available hai. Iska matlab hai duniya bhar ke developers isme contribute kar rahe hain aur ise behtar bana rahe hain.

Flutter Kaise Kaam Karta Hai? (Simple Explanation)

Sochiye aapko ek ghar banana hai. Aap Flutter ko ek aisi factory samjhiye jo aapke design (code) ko lekar, directly bricks aur cement (phone ke pixels) se ghar (app) bana deti hai. Ye kisi bhi platform ke beech mein jaane ki zaroorat nahi padti, isliye app bahot tez chalti hai.

Neeche ek simple Flutter code hai jo screen par "Hello, Porexo!" likhta hai:

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('My First Flutter App'),
        ),
        body: Center(
          child: Text('Hello, Porexo!'),
        ),
      ),
    );
  }
}

Is code ko run karte hi, aapko ek simple app milegi jisme upar title bar hoga aur beech mein "Hello, Porexo!" likha hoga.

Kya Aapko Flutter Seekhna Chahiye?

Agar aap naye developer hain aur mobile app development mein interest rakhte hain, toh Flutter ek shandaar shuruaat hai. Kyunki:

1. Aapko alag-alag languages (Java, Swift) seekhne ki zaroorat nahi hai.
2. Hot Reload ki wajah se seekhna aur experiment karna aasaan hai.
3. Iska community bahot bada aur helpful hai, toh aapko help aasani se mil jaayegi.

Agar aap already web developer hain, toh Dart language JavaScript jaisi lagti hai, isliye aapko adapt karna aasaan hoga.
