What is Flutter WebView?

Suppose you have a responsive web page and you want to display the in app you have built for android and iOS devices. Then you have to use a package webview_flutter to display. The page you are showing on the mobile devices is WebView. It means the same design and the same webpage will be displayed on the mobile app.

How to manipulate Flutter Webview

If you are using the webview_flutter package for displaying URLs then you can easily manipulate the display using the various attributes provided by the WebView() constructor. We will discuss most of them here.

1. javascriptMode

By default, javascript mode is restricted for the web view URL. The attribute javascriptMode.unrestricted enables to run Javascript on the URL.

javascriptMode: JavascriptMode.unrestricted,

Now you are able to click anything on the website and the page will respond.

2. zoomEnabled

It accepts a boolean value and allows you to zoom the webpage using the on-screen zoom controls and gestures.

3. userAgent

Just like you sent userAgenet in the header of the HTML file. You can also send userAgent on the header to the webview. It is of string type.

userAgenet: "'Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 
(KHTML, like Gecko) Chrome/62.0.3202.94 Mobile Safari/537.36'"

4. onProgress

Suppose you want to show the progress bar until the webpage is fully loaded to the screen. The attribute onProgress allows you to do so.  For example, I want to display a circular progress bar until the web page loading is in progress.

          children: [
                initialUrl: "https://www.codethebest.com/",
                javascriptMode: JavascriptMode.unrestricted,
                zoomEnabled: true,
                onProgress: (finish) {
                  setState(() {
                    isLoading = false;
                ? Center(
                    child: CircularProgressIndicator(),
                : Stack()

Here the flutter stack will be used to show the progress indicator above the webview.


Webview allows you to convert any mobile responsive web application to an android app. There are also various manipulations you can do with the webview_flutter packager. But most of them are defined here.
