A new Flutter plugin based on my ClashKit and my Tun2Socks-Android
My ClashKit forked from AppleClash/clash-apple, my Tun2Socks-Android forked from universal-android-tun2socks

pubspec.yaml

dependencies:
  clash_flt:
    git:
      url: https://github.com/LondonX/clash_flt.git

Android

1. Requires minSdkVersion 21

3. Add implementation files("ClashKit.aar") in <project-root>/android/app/build.gradle's dependencies section.

iOS

1. Requires iOS 13 or newer.
2. As gomobile stop supporting armv7a, you need to exlude this architecture in XCode.

• Open Runner.xcodeproj, select Runner in PROJECT list on the left.
• In Build Settings->All->Architectures, set value to arm64.

3. Modify Runner.xcodeproj

• Open Runner's Signing & Capabilities tab.
• You may need to enable Network Extension in Apple Developer Account page/Certificates, IDs & Profiles/Identifiers/YOUR_BUNDLE_ID/Edit/Network Extensions checkbox, before add Network Extension and provision.
• Add Network Extension and Personal VPN.
• Check App Proxy and Packet Tunnel of Network Extension.

4. Add project Target of Network-Extension

• Create a Target named PacketTunnel, the XCode will auto create a file named PacketTunnelProvider.swift.
• Open PacketTunnel's Signing & Capabilities tab.
• Add Network Extension and Personal VPN, just as step 3.
• Add ClashKit.xcframework into PacketTunnel's Frameworks and Libraries an select Do Not Embed.
• Modify PacketTunnelProvider.swift by paste from Example's PacketTunnelProvider.swfit

5. Add app group

• Create a App Group named group.<yourBundleId> both in Runner and PacketTunnel Target.
