Example Flutter VPN Application

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.

Cannot connect to vpn servers!

Server is unreachable, also can you explain about how did you import the vpn api in the app, and how to add/create own server addresses.
