📝 First Project Setup

FLX CLI দিয়ে আপনার প্রথম Clean Architecture Flutter project তৈরি করুন!

🎯 Project Structure Setup

1. Flutter Project তৈরি করুন

# নতুন Flutter project তৈরি করুন
flutter create my_flx_app
cd my_flx_app

2. FLX CLI Configuration

# Global config check করুন
flx config --list

# Project-specific config set করুন (optional)
flx config --state getx --local

3. Dependencies যোগ করুন

pubspec.yaml এ এই dependencies গুলো যোগ করুন:

GetX প্রোজেক্টের জন্য:

dependencies:
  flutter:
    sdk: flutter
  get: ^4.6.6
  dartz: ^0.10.1
  equatable: ^2.0.5
  dio: ^5.3.2
  hive: ^2.2.3
  hive_flutter: ^1.1.0

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_lints: ^3.0.0
  hive_generator: ^2.0.1
  build_runner: ^2.4.7
  mockito: ^5.4.2

BLoC প্রোজেক্টের জন্য:

dependencies:
  flutter:
    sdk: flutter
  flutter_bloc: ^8.1.3
  bloc: ^8.1.2
  dartz: ^0.10.1
  equatable: ^2.0.5
  dio: ^5.3.2
  hive: ^2.2.3
  hive_flutter: ^1.1.0

dev_dependencies:
  flutter_test:
    sdk: flutter
  flutter_lints: ^3.0.0
  bloc_test: ^9.1.4
  hive_generator: ^2.0.1
  build_runner: ^2.4.7
  mockito: ^5.4.2

4. Dependencies Install করুন

flutter pub get

🏗 Folder Structure Setup

Core Structure তৈরি করুন

# Core directories manually তৈরি করুন
mkdir -p lib/core/error
mkdir -p lib/core/network
mkdir -p lib/core/usecases
mkdir -p lib/core/utils
mkdir -p lib/features

Core Files তৈরি করুন

lib/core/error/failures.dart:

import 'package:equatable/equatable.dart';

abstract class Failure extends Equatable {
  final String message;
  
  const Failure([this.message = 'An unexpected error occurred']);
  
  @override
  List<Object> get props => [message];
}

class ServerFailure extends Failure {
  const ServerFailure([super.message = 'Server error occurred']);
}

class NetworkFailure extends Failure {
  const NetworkFailure([super.message = 'Network error occurred']);
}

class CacheFailure extends Failure {
  const CacheFailure([super.message = 'Cache error occurred']);
}

class ValidationFailure extends Failure {
  const ValidationFailure(String message) : super(message);
}

lib/core/usecases/usecase.dart:

import 'package:dartz/dartz.dart';
import '../error/failures.dart';

abstract class UseCase<Type, Params> {
  Future<Either<Failure, Type>> call(Params params);
}

class NoParams {
  const NoParams();
}

5. Network Setup (Optional)

lib/core/network/network_info.dart:

abstract class NetworkInfo {
  Future<bool> get isConnected;
}

📱 GetX App Setup (Optional)

main.dart এ GetX setup:

import 'package:flutter/material.dart';
import 'package:get/get.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return GetMaterialApp(
      title: 'FLX Clean App',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const HomePage(),
    );
  }
}

class HomePage extends StatelessWidget {
  const HomePage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('FLX Clean App'),
      ),
      body: const Center(
        child: Text(
          'Ready to build features with FLX CLI!',
          style: TextStyle(fontSize: 18),
        ),
      ),
    );
  }
}
