Getting started

To use this plugin, add flutter_dev_packages as a dependency in your pubspec.yaml file. For example:

dependencies:
  flutter_dev_packages:
    git:
      url: https://github.com/Dev-hwang/flutter_dev_packages.git
      ref: master

Usage

플러그인에 포함된 패키지나 유틸리티를 사용하려면 플랫폼별 초기 설정이 필요하다.

🐤 logger package

1. sentry.io 회원가입을 진행한다.

2. 프로젝트를 생성하고 DSN 값을 얻는다.

3. 프로젝트의 main 함수에 아래와 같이 Sentry 플러그인을 초기화한다.

import 'dart:async';

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

const String kSentryDsn = 'https://80ab98a9a0b448e0b591d2d5db20c47b@o332735.ingest.sentry.io/0';

void main() {
  runZonedGuarded(() async {
    await Sentry.init((options) {
      options.dsn = kSentryDsn;
    });

    runApp(const ExampleApp());
  }, (error, stackTrace) async {
    await Logger.f('FATAL EXCEPTION', error: error, stackTrace: stackTrace);
  });
}

🐤 network package

network 패키지 사용 시 아래 권한 추가 필요

Android

/android/app/src/main/AndroidManifest.xml

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Prepare release

🌟 keystore 생성 및 서명 구성

1. 터미널에 아래 명령어를 입력하여 keystore 파일을 생성한다.

맥/리눅스에서는 아래 명령어를 사용하세요:

keytool -genkey -v -keystore ~/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key

윈도우에서는 아래 명령어를 사용하세요:

keytool -genkey -v -keystore c:/Users/USER_NAME/key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key

2. /android/key.properties 파일을 생성하고 아래 내용을 입력한다.

storePassword=<password from previous step>
keyPassword=<password from previous step>
keyAlias=key
storeFile=<key store 파일 위치, 예) /Users/<user name>/key.jks>

3. /android/app/build.gradle 파일에 아래 코드를 추가한다.

def keystoreProperties = new Properties()
def keystorePropertiesFile = rootProject.file('key.properties')
if (keystorePropertiesFile.exists()) {
    keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
}

android {
    // 기본 코드 생략..

    signingConfigs {
        release {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile file(keystoreProperties['storeFile'])
            storePassword keystoreProperties['storePassword']
        }
    }

    buildTypes {
        release {
            signingConfig signingConfigs.release
        }
    }
}

🌟 코드 난독화

1. /android/app/proguard-rules.pro 파일을 생성하고 아래 내용을 입력한다.

-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }
-keep class io.flutter.**  { *; }
-keep class io.flutter.plugins.**  { *; }
-dontwarn io.flutter.embedding.**

2. /android/app/build.gradle 파일에 아래 코드를 추가한다.

android {
    // 기본 코드 생략..

    buildTypes {
        release {
            shrinkResources true
            minifyEnabled true
            signingConfig signingConfigs.release
            proguardFiles getDefaultProguardFile(
                    'proguard-android-optimize.txt'),
                    'proguard-rules.pro'
        }

        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile(
                    'proguard-android-optimize.txt'),
                    'proguard-rules.pro'
        }
    }
}
