Installation

For Android

Modify your app/build.gradle to use abiFilter because flutter doesn't support multi-architecture in single apk #18494.

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

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.
