CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Commands

Development

• flutter run - Run the app in development mode
• flutter test - Run all tests
• dart run fl_build -p PLATFORM - Build the app for specific platform (see fl_build package)

Code Generation

• dart run build_runner build --delete-conflicting-outputs - Generate code for models with annotations (json_serializable, freezed, hive, riverpod)
  • Every time you change model files, run this command to regenerate code (Hive adapters, Riverpod providers, etc.)
  • Generated files include: *.g.dart, *.freezed.dart files

Testing

• flutter test - Run unit tests
• flutter test test/battery_test.dart - Run specific test file

Architecture

This is a Flutter application for managing Linux servers with the following key architectural components:

Project Structure

• lib/core/ - Core utilities, extensions, and routing
• lib/data/ - Data layer with models, providers, and storage
  • model/ - Data models organized by feature (server, container, ssh, etc.)
  • provider/ - Riverpod providers for state management
  • store/ - Local storage implementations using Hive
• lib/view/ - UI layer with pages and widgets
• lib/generated/ - Generated localization files
• lib/hive/ - Hive adapters for local storage

Key Technologies

• State Management: Riverpod with code generation (riverpod_annotation)
• Local Storage: Hive for persistent data with generated adapters
• SSH/SFTP: Custom dartssh2 fork for server connections
• Terminal: Custom xterm.dart fork for SSH terminal interface
• Networking: dio for HTTP requests
• Charts: fl_chart for server status visualization
• Localization: Flutter's built-in i18n with ARB files
• Code Generation: Uses build_runner with json_serializable, freezed, hive_generator, riverpod_generator

Data Models

• Server management models in lib/data/model/server/
• Container/Docker models in lib/data/model/container/
• SSH and SFTP models in respective directories
• Most models use freezed for immutability and json_annotation for serialization

Features

• Server status monitoring (CPU, memory, disk, network)
• SSH terminal with virtual keyboard
• SFTP file browser
• Docker container management
• Process and systemd service management
• Server snippets and custom commands
• Multi-language support (12+ languages)
• Cross-platform support (iOS, Android, macOS, Linux, Windows)

State Management Pattern

• Uses Riverpod providers for dependency injection and state management
• Uses Freezed for immutable state models
• Providers are organized by feature in lib/data/provider/
• State is often persisted using Hive stores in lib/data/store/

Build System

• Uses custom fl_build package for cross-platform building
• make.dart script handles pre/post build tasks (metadata generation)
• Supports building for multiple platforms with platform-specific configurations
• Many dependencies are custom forks hosted on GitHub (dartssh2, xterm, fl_lib, etc.)

Important Notes

• Never run code formatting commands - The codebase has specific formatting that should not be changed
• Always run code generation after modifying models with annotations (freezed, json_serializable, hive, riverpod)
• Generated files (*.g.dart, *.freezed.dart) should not be manually edited
• AGAIN, NEVER run code formatting commands.
• USE dependency injection via GetIt for services like Stores, Services and etc.
• Generate all l10n files using flutter gen-l10n command after modifying ARB files.
