Example Flutter VPN App

Installation

For Android

Modify your app/build.gradle to use abiFilter because flutter doesn't apply abiFilter for target platform yet.

android {
    ...
    buildTypes {
        ...
        release {
            ...
            ndk {
                    if (project.hasProperty('target-platform')) {
                        if (project.property('target-platform') == 'android-arm,android-arm64')
                            abiFilters 'armeabi-v7a', 'arm64-v8a'
                        else if (project.property('target-platform') == 'android-arm')
                            abiFilters 'armeabi-v7a'
                        else if (project.property('target-platform') == 'android-arm64')
                            abiFilters 'arm64-v8a'
                    }
                }
            }
    }
}

The plugin will automatically download pre-build native libraries from here if they haven't been downloaded.

For iOS

You need to open Personal VPN and Network Extensions capabilities in Xcode: see Project->Capabilities.

VPN connection errors are handled in swift code, you need to use Xcode to see connection errors if there is any.
