Getting Started with Flutter: Software Prerequisites Installations

chalo shuru karte hain. Flutter development start karne ke liye kuch software prerequisites hain jo pehle install karni padti hain. Pehle hum inke baare mein baat karenge, phir native aur cross-platform apps ka comparison karenge.

JDK (Java Development Kit) Installation:

JDK kya hai?

JDK ek software development kit hai jo Java applications banane ke liye zaroori hoti hai. Flutter me, JDK zaroori hai kyunki Android apps ke liye Java use hota hai.

Installation Steps:

Oracle ki website se JDK download karo.

Installer ko run karo aur on-screen instructions follow karo.

Android Studio Installation:

Android Studio kya hai?

Android Studio ek Integrated Development Environment (IDE) hai jo Android apps develop karne ke liye use hota hai. Isme apko bohot sare tools milte hain jo development easy banate hain.

Installation Steps:

Android Studio ki official website se installer download karo.

Installer ko run karo aur sab dependencies install karne do (jaise Android SDK).

Installation ke baad, 'SDK Manager' open karo aur necessary SDK tools aur platforms install karo.

Flutter & Dart SDK Installation:

Flutter kya hai?

Flutter ek open-source UI software development kit hai jo Google ne banaya hai. Isse aap ek hi codebase se Android aur iOS dono ke liye apps bana sakte ho.

Dart kya hai?

Dart programming language hai jo Flutter use karta hai. Yeh Google ne develop ki hai aur yeh easy to learn aur powerful language hai.

Installation Steps:

Flutter ki official website se latest version download karo.

Zip file ko extract karo aur extracted folder ko kisi safe location (jaise C:\flutter) me rakho.

Flutter ke bin folder ko system PATH me add karo. (Yeh steps different OS ke liye thoda different ho sakte hain).

Command Prompt ya Terminal open karo aur flutter doctor command run karo. Yeh check karega ki sab dependencies sahi se installed hain ya nahi. Agar kuch missing hai, to woh bhi bata dega.

Comparison of Native and Cross-Platform Developed Apps

Native App Development:

Definition:

Native apps wo hoti hain jo specific platform (jaise Android ya iOS) ke liye banayi jati hain using platform-specific languages (Android ke liye Java/Kotlin, iOS ke liye Swift/Objective-C).

Advantages:

High performance kyunki directly hardware aur OS features use karti hain.

Better UI/UX kyunki platform-specific design guidelines follow karti hain.

Disadvantages:

Development time aur cost zyada hoti hai kyunki har platform ke liye alag codebase banana padta hai.

Cross-Platform App Development:

Definition:

Cross-platform apps wo hoti hain jo ek hi codebase se multiple platforms (jaise Android aur iOS) ke liye banayi jati hain. Flutter is tarah ka ek framework hai.

Advantages:

Single codebase hone ki wajah se development time aur cost kam hoti hai.

Maintain karna easy hota hai kyunki changes har platform pe ek saath apply ho jate hain.

Disadvantages:

Performance native apps ke comparison me thodi kam ho sakti hai.

Kuch complex platform-specific features implement karna mushkil ho sakta hai.

Summary

Flutter development start karne ke liye pehle JDK, Android Studio, aur Flutter & Dart SDK install karna zaroori hai. Native apps specific platform ke liye banti hain aur high performance aur best UI/UX deti hain, lekin time-consuming aur costly hoti hain. Cross-platform apps, jaise Flutter se bani hui, ek hi codebase se multiple platforms ke liye banti hain, jo time aur cost efficient hoti hain, lekin kabhi kabhi performance aur complex features pe compromise karna padta hai.
