+# 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
+- `dart run fl_build -p PLATFORM` - Build the app for specific platform (see fl_build package)
+- `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.
+- USE `hive_ce` not `hive` package for Hive integration.
+  - Which no need to config `HiveField` and `HiveType` manually.
+- USE widgets and utilities from `fl_lib` package for common functionalities.
+  - Such as `CustomAppBar`, `context.showRoundDialog`, `Input`, `Btnx.cancelOk`, etc.
+  - You can use context7 MCP to search `lppcg fl_lib KEYWORD` to find relevant widgets and utilities.
+- USE `libL10n` and `l10n` for localization strings.
+  - `libL10n` is from `fl_lib` package, and `l10n` is from this project.
+  - Before adding new strings, check if it already exists in `libL10n`.
+  - Prioritize using strings from `libL10n` to avoid duplication, even if the meaning is not 100% exact, just use the substitution of `libL10n`.
+- Split UI into Widget build, Actions, Utils. use `extension on` to achieve this

 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
 
-  To protect your rights, we need to prevent others from denying you
-these rights or asking you to surrender the rights.  Therefore, you have
-certain responsibilities if you distribute copies of the software, or if
-you modify it: responsibilities to respect the freedom of others.
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
 
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must pass on to the recipients the same
-freedoms that you received.  You must make sure that they, too, receive
-or can get the source code.  And you must show them these terms so they
-know their rights.
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
 
-  Developers that use the GNU GPL protect your rights with two steps:
-(1) assert copyright on the software, and (2) offer you this License
-giving you legal permission to copy, distribute and/or modify it.
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
 
-  For the developers' and authors' protection, the GPL clearly explains
-that there is no warranty for this free software.  For both users' and
-authors' sake, the GPL requires that modified versions be marked as
-changed, so that their problems will not be attributed erroneously to
-authors of previous versions.
-
-  Some devices are designed to deny users access to install or run
-modified versions of the software inside them, although the manufacturer
-can do so.  This is fundamentally incompatible with the aim of
-protecting users' freedom to change the software.  The systematic
-pattern of such abuse occurs in the area of products for individuals to
-use, which is precisely where it is most unacceptable.  Therefore, we
-have designed this version of the GPL to prohibit the practice for those
-products.  If such problems arise substantially in other domains, we
-stand ready to extend this provision to those domains in future versions
-of the GPL, as needed to protect the freedom of users.
-
-  Finally, every program is threatened constantly by software patents.
-States should not allow patents to restrict development and use of
-software on general-purpose computers, but in those that do, we wish to
-avoid the special danger that patents applied to a free program could
-make it effectively proprietary.  To prevent this, the GPL assures that
-patents cannot be used to render the program non-free.
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
