[jamiemm]

System info

Issue occurs on: iOS
Plugin name: Network Info Plus
Plugin version: 1.1.0
Flutter doctor output:

[✓] Flutter (Channel stable, 2.2.1, on macOS 11.2.3 20D91 darwin-x64, locale en-GB)
[✓] Android toolchain - develop for Android devices (Android SDK version 30.0.2)

Steps to Reproduce

1. flutter pub add network_info_plus
2. import 'package:network_info_plus/network_info_plus.dart'; in one of the project .dart files
3. attempt to build and run the app on an iOS emulator (iPhone 11 iOS 14.2)
4. The build fails with the following error:

/Users/jamie/.pub-cache/hosted/pub.dartlang.org/network_info_plus-1.1.0/ios/Classes/getgateway.c:18:14: fatal error: 'net/route.h' file not found
        #include <net/route.h>

5. If I change the following lines in ios/Classes/getgateway.c:

#if TARGET_IPHONE_SIMULATOR
    #include <net/route.h>
    #define TypeEN    "en1"
#else
    #include "route.h"
    #define TypeEN    "en0"
#endif

To the following:

    #include "route.h"
    #define TypeEN    "en0"

The build is successful, and the package works correctly.
