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 👍🏻Thanks @netyouli and Tun2SocksKit repo for iOS tun implementation.

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

1. Requires minSdkVersion 21
2. Copy ClashKit.aar and tun2socks.aar into <project-root>/android/app/.
3. Add implementation files("ClashKit.aar") and implementation files("tun2socks.aar") in <project-root>/android/app/build.gradle's dependencies section.

1. Requires iOS 13 or newer. ≥15 is recommended because os iOS memory limitation of packet tunnel
2. As gomobile stop supporting armv7a, you need to exclude this architecture in XCode.
   • Open Runner.xcodeproj, select Runner in PROJECT list on the left.
   • In Build Settings->All->Architectures, set value to arm64.
   • Add ClashKit.xcframework into Runner's Frameworks and Libraries an select Do Not Embed.
   • Add Tun2SocksKit-main by Swift Package Manager (SPM) from https://github.com/EbrahimTahernejad/Tun2SocksKit or <project-root>/ios/Tun2SocksKit-main.
   • Add Tun2SocksKit lib into Frameworks and Libraries of PacketTunnel target.
   • (Optional) Add HevSocks5Tunnel.xcframework
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.
   • 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.
