A Plugin Project That Support Get and Set Status of Network Proxy

network_proxy

A plugin project that support get and set status of network proxy.

Getting Started

This project is a starting point for a Flutter plug-in package, a specialized package that includes platform-specific implementation code for Android and/or iOS.

For help getting started with Flutter development, view the online documentation, which offers tutorials, samples, guidance on mobile development, and a full API reference.

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add network_proxy

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  network_proxy: ^1.0.0

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:network_proxy/network_proxy.dart';

example/lib/main.dart

import 'dart:io';

import 'package:flutter/material.dart';
import 'dart:async';

import 'package:flutter/services.dart';
import 'package:network_proxy/network_proxy.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  final _networkProxyPlugin = NetworkProxy();
  final _hostInput = TextEditingController(text: '127.0.0.1');
  final _portInput = TextEditingController(text: '10808');
  NetworkProxyType _type = NetworkProxyType.socks;

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  // Platform messages are asynchronous, so we initialize in an async method.
  Future<void> initPlatformState() async {
    String platformVersion;
    // Platform messages may fail, so we use a try/catch PlatformException.
    // We also handle the message potentially returning null.
    try {
      platformVersion = await _networkProxyPlugin.getPlatformVersion() ??
          'Unknown platform version';
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // If the widget was removed from the tree while the asynchronous platform
    // message was in flight, we want to discard the reply rather than calling
    // setState to update our non-existent appearance.
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),

              DropdownButton<NetworkProxyType>(
                value: _type,
                items: NetworkProxyType.values

                      ),
                    )
                    .toList(),
                onChanged: (value) {
                  if (value == null) return;
                  _type = value;
