## Feedback, Issues and Questions

If you encounter any issue, or you have an idea to improve, please:

- Search through [existing open and closed GitHub Issues](https://github.com/hiddify/hiddify-app/issues) for the answer first. If you find a relevant topic, please comment on the issue.
- If none of the issues are relevant, please add a new [issue](https://github.com/hiddify/hiddify-app/issues/new/choose) following the templates and provide as much relevant information as possible.

## Adding new Features

When contributing a complex change to the Hiddify repository, please discuss the change you wish to make within a GitHub issue with the owners of this repository before making the change.


## Development

### Adding Feature / Fix bug in Core:
Please follow our [Go Core Development repository](https://github.com/hiddify/hiddify-next-core/main/CONTRIBUTING.m).

### Working with the Flutter Code
Hiddify uses [Flutter](https://flutter.dev), make sure that you have the correct version installed before starting development. You can use the following commands to check your installed version:

```shell
$ flutter --version

# example response
Flutter 3.13.4 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 367f9ea16b (4 weeks ago) • 2023-09-12 23:27:53 -0500
Engine • revision 9064459a8b
Tools • Dart 3.1.2 • DevTools 2.25.0
```


We recommend using [Visual Studio Code](https://docs.flutter.dev/development/tools/vs-code) extensions for development.

#### Setting up the Environment

We have extensive use of code generation in the form of [freezed](https://github.com/rrousselGit/freezed), [riverpod](https://github.com/rrousselGit/riverpod), etc. So it's generate these before running the code. Execute the following make commands in order:
Assuming you have not built the `hiddify-core` and want to use [existing releases](https://github.com/hiddify/hiddify-next-core/releases), you should run the following command (based on your target platform):


- `make windows-prepare`
- `make linux-prepare` 
- `make macos-prepare`
- `make ios-prepare`
- `make android-prepare`


##### build the `hiddify-core` from source (Optional)
If you want to build the `hiddify-core` from source after `make prepare`, use:
- `make build-windows-libs`
- `make build-linux-libs` 
- `make build-macos-libs`
- `make build-ios-libs`
- `make build-android-libs`

#### Run Release Build on a Device

To run the release build on a device for testing, we have to get the Device ID first by running the following command:

```shell
$ flutter devices

# example response
3 connected devices:

2211143G (mobile) • 35492ae2 • android-arm64  • Android 13 (API 33)
Windows (desktop) • windows  • windows-x64    • Microsoft Windows [Version 10.0.22000.2482]
Chrome (web)      • chrome   • web-javascript • Google Chrome 117.0.5938.149
```

Then we can use one of the listed devices and execute the following command to build and run the app on this device:

```shell
flutter run
# or
flutter run --device-id=35492ae2
```

## Release

We use [flutter_distributor](https://github.com/leanflutter/flutter_distributor) for packaging. [GitHub action](https://github.com/hiddify/hiddify-app/blob/main/.github/workflows/build.yml) is triggered on every release tag and will create a new GitHub release.
After setting up the environment, use the following make commands to build the release version:

- `make windows-release`
- `make linux-release`
- `make macos-release`
- `make android-release`
- `make ios-release`
