Release v1.1.6+1

Release Notes - Env Builder CLI

v1.1.6+1 (Latest)

Release Date: 12/07/2025

🚀 New Features

• Assets Command: New env_builder assets command for encrypting and embedding assets directly into Dart code
  • Asset Discovery: Automatically scans assets/ directory for supported files
  • Multi-format Support: Images (PNG, JPG, JPEG, GIF, WebP), Videos (MP4, WebM, MOV, AVI, MKV), and SVGs
  • Compression & Optimization: Automatic image compression and SVG minification (configurable)
  • Encryption Options: XOR (fast, default) and AES (secure) encryption methods
  • Zero Runtime Dependencies: Assets embedded as constants, no pubspec.yaml changes needed

🔧 Generated APIs

• Raw Access: Direct access to encrypted asset data (Uint8List/String)
• Widget Helpers: Pre-built widgets for images, SVGs, and video controllers
• Flutter_gen Compatible: Drop-in replacement API with the same structure as flutter_gen

📖 Usage Examples

# Encrypt and embed assets with XOR encryption (default)
env_builder assets

# Use AES encryption for sensitive assets
env_builder assets --encrypt=aes

# Skip compression and minification
env_builder assets --no-compress

# Verbose output during generation
env_builder assets --verbose

💻 Generated Code Usage

import 'package:app_assets/src/generated/assets.gen.dart';

// Access encrypted assets
final logoBytes = Assets.logo; // Uint8List
final videoPlayer = await Assets.videos.intro.video(); // VideoPlayer widget
final svgPicture = Assets.svgs.icon.svg(); // SvgPicture widget

// Flutter_gen compatible API
final image = Assets.images.logo; // AssetGenImage

🔒 Security & Performance

• Encrypted Storage: All assets are encrypted before embedding
• Type Safety: Compile-time safe access prevents typos
• No Runtime Overhead: Assets loaded from memory, no file I/O operations
• Build-time Only: Encryption/decryption happens at build time only

📋 Compatibility

• Dart SDK: ^3.8.1+
• Flutter: Compatible with existing projects
• Backward Compatible: All existing features remain unchanged

Release v1.1.5

Release Notes - Env Builder CLI

v1.1.5 (Latest)

Release Date: 20/11/2025

Changes

• Command Structure Refactoring: Reorganized the command structure to make apk and aab commands independent top-level commands instead of being subcommands of the build command.
  • Before: env_builder build apk, env_builder build aab
  • After: env_builder apk, env_builder aab
• Build Command Fix: Fixed issue where running env_builder build --env-file=.env without a subcommand would result in "Missing subcommand" error. Now the build command can be used directly for generating env packages.

New Usage

# Build env package
env_builder build --env-file=.env

# Build APK
env_builder apk

# Build AAB
env_builder aab

Release v1.1.3

Release Notes - v1.1.3

Overview

Env Builder CLI v1.1.3 introduces new command-line options to provide more flexibility and control over the build process.

New Features

--output-dir Option

• Allows specifying a custom output directory for the generated environment package
• Default remains env if not specified
• Usage: env_builder build --output-dir=custom_env

--no-encrypt Option

• Skips the encryption prompts for sensitive variables
• Useful for automated builds or when encryption is not needed
• Usage: env_builder build --no-encrypt

--verbose Option

• Enables detailed output during the build process
• Provides more information for troubleshooting and monitoring
• Usage: env_builder build --verbose

Usage Examples

# Build with custom directory
env_builder build --output-dir=my_env_package

# Build without encryption prompts
env_builder build --no-encrypt

# Build with detailed logging
env_builder build --verbose

# Combine options
env_builder build --output-dir=custom --no-encrypt --verbose

Improvements

• Enhanced error handling for missing directories
• Better user prompts for encryption decisions
• Improved logging for debugging purposes

Release v1.1.2

Release Note v1.1.2

Changes

• Refactored code structure for improved maintainability
• Updated example package structure
• Modified the env package generation's command

Release V1.1.1

With this env_builder_cli release, user will be asked if he want to encrypt .env files in his generated env package.
If yes, his must choose a secret code that he must not forget. That secret code will be needed while decrypting the encrypted files.

Release v1.1.0 – Env Builder CLI

🚀 Release v1.1.0 – Env Builder CLI

env_builder_cli is a Dart command-line tool that automates environment file management in Flutter projects and now includes built-in encryption/decryption support for .env files.

✨ Features

• Manage multiple .env files (.env, .env.development, .env.production, .env.staging, etc.).
• Automatically generate a Flutter env package inside packages/env/.
• Generate Dart files (env.dev.dart, env.prod.dart, etc.) with Envied annotations.
• Auto-update dependencies in pubspec.yaml and run flutter pub get.
• Minimal and clean CLI output.

🔒 New: Environment File Encryption / Decryption

• AES-based encryption with a password-derived key.
• Protect sensitive data such as API keys, tokens, and database credentials.
• CLI commands for quick usage:

# Encrypt
env_builder encrypt .env .env.enc --password superSecretKey  

# Decrypt
env_builder decrypt .env.enc .env --password superSecretKey

• If the password is invalid or the file is corrupted, a clear error message is shown.
• Recommended workflow: commit only the encrypted .env.enc file, not the decrypted .env.

🛠️ Prerequisites

• Flutter SDK installed and added to your system PATH
• Install env_builder_cli from pub.dev

dart pub global activate env_builder_cli

✅ With this release, you can safely share environment files across teams and automate their integration into Flutter projects.
