In-App Localhost Server

The InAppLocalhostServer class allows you to create a simple server on http://localhost:[port]/ in order to be able to load your assets file on a server. The default port value is 8080.

Basic Usage

To start and stop the server, you can use the InAppLocalhostServer.start and InAppLocalhostServer.stop methods.


import 'dart:io';

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

final InAppLocalhostServer localhostServer = new InAppLocalhostServer();

Future main() async {

// start the localhost server
await localhostServer.start();

if (Platform.isAndroid) {
await AndroidInAppWebViewController.setWebContentsDebuggingEnabled(true);

runApp(MaterialApp(home: MyApp()));

class MyApp extends StatefulWidget {

_MyAppState createState() => new _MyAppState();

class _MyAppState extends State<MyApp> {
