PART 2 Tutorial on Flutter Webview

Part 1 on TechPadi

Convert a website into an application in just a few minutes – FLUTTER WEBVIEW TUTORIAL (Part 1).

Let get started

We will make use of the flutter_inappwebview package for this example two. To install this package in your app just paste it in your pubspec.yaml file.

In the webview folder create another dart file for example two, you can name it example2.dart.
In the dart file, import the two necessary package 🎁

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

Create a stateful widget and name the class WebExampleTwo or your choice 🤷‍♂️

class WebExampleTwo extends StatefulWidget {
  WebExampleTwo({Key key}) : super(key: key);

  @override
  _WebExampleTwoState createState() => _WebExampleTwoState();
}

class _WebExampleTwoState extends State<WebExampleTwo> {

  @override
  Widget build(BuildContext context) {
    return Scaffold();
  }
}

We need a controller and double datatype for showing the loading indicator on every page load, so set this under your class State

class _WebExampleTwoState extends State<WebExampleTwo> {
  InAppWebViewController _webViewController;
  double progress = 0;

Body

     body: Container(
        child: Column(
          children: [
            progress < 1.0
                ? LinearProgressIndicator(
                    value: progress,
                    backgroundColor: Colors.white,
                    valueColor:
                        AlwaysStoppedAnimation<Color>(Colors.green[800]),
                  )
                : Center(), // this perform the loading on every page load
            Expanded(
              child: InAppWebView(
                initialUrl: 'https://obounce.net', // your website url
                initialOptions: InAppWebViewGroupOptions(
                  crossPlatform: InAppWebViewOptions(
                    javaScriptEnabled: true,
                    javaScriptCanOpenWindowsAutomatically: true,
                  ),
                ),
                onProgressChanged: (_, load) {
                  setState(() {
                    progress = load / 100;
                  });
                },
                onWebViewCreated: (controller) {
                  _webViewController = controller;
                },
              ),
            )
          ],
        ),
      ),

To create a reload button or icon for a reload action, let’s create an icon for that on our appBar

AppBar

      appBar: AppBar(
        title: Text("O'Bounce Technologies"),
        centerTitle: true,
        elevation: 0,
        actions: [
          IconButton(
            onPressed: () {
              if (_webViewController != null) {
                _webViewController.reload();
              }
            },
            icon: Icon(Icons.refresh),
          ),
        ],
      ),

And that’s all for the WebExampleTwo page you can now move to the homepage.dart file or any page you want your user to click the button to navigate to the WebExampleTwo page.

              MaterialButton(
                onPressed: () {
                  Navigator.push(context,
                      MaterialPageRoute(builder: (_) => WebExampleTwo()));
                },
                child: Text(
                  'Example 2',
                  style: TextStyle(color: Colors.white),
                ),
                color: Colors.green,
                padding: EdgeInsets.symmetric(horizontal: 70, vertical: 12),
              ),

And that’s all the major stuff you need to know 👌, For more explanation kindly check the video tutorial.
