You can prevent navigation in webview through navigation delegate property like following:
<pre><code>WebView(
 debuggingEnabled: true,
 initialUrl: _currentURL,
 onWebViewCreated: (controller) {
 _controller = controller;
 return _controller;
 },
 onPageFinished: (url) {
 if (url.contains(ConstUtils.course)) {
 updateProfile();
 }
 },
 navigationDelegate: (navigation) =&gt; NavigationDecision.prevent,
 onWebResourceError: (error) {
 NavigationUtils(context).popCurrentPage();
 },
 onPageStarted: (url) {
 
 },
 javascriptMode: JavascriptMode.unrestricted,
 ),
</code></pre>

blocks|key|3563039|text|要禁用将用户导航到另一个页面，您可以使用onPageCommitVisible回调来确定用户正在单击重定向到另一个页面的url，因此只需在其中调用goBack|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|3563040|+InAppWebView(

For disable navigate user to another page you can use onPageCommitVisible call back to determine the user is click on url that redirect to another one, so just call goBack inside it
<pre><code> InAppWebView(
 onPageCommitVisible: (con,uri){
 print(&quot;url ${uri.toString()}&quot;);
 con.goBack();
 },

 ),
</code></pre>

<h2>Disable navigation <code>InAppWebView</code>:-</h2>
we have <code>onUpdateVisitedHistory</code> property in <code>Inappwebview</code> widget.Using this <code>onUpdateVisitedHistory</code> property we can listen url changes in the <code>Inappwebview</code> widget.So disable navigation we can use <code>webcontroller.goback()</code> method.
widget code:
<pre><code>InAppWebView(
 key: webViewKey,
 onWebViewCreated: (controller) {
 webViewController = controller;
 _loadHtmlFromAssets();
 },
 onUpdateVisitedHistory: (controller, url, androidIsReload) {
 if (url!.host.contains(&quot;google.com&quot;)) {
 webViewController?.goBack();
 //You can do anything
 Navigator.push(
 context,
 MaterialPageRoute(builder: (context) =&gt; const Screen1()),
 );
 //Prevent that url works
 return;
 } else if (url.host.contains(&quot;yahoo.com&quot;)) {
 //You can do anything
 webViewController?.goBack();
 Navigator.push(
 context,
 MaterialPageRoute(builder: (context) =&gt; const Screen3()),
 );
 //Prevent that url works
 return;
 } else if (url.host.contains(&quot;duckduckgo.com&quot;)) {
 //You can do anything

I'm new to Flutter, and I want to put a web view between other widgets and I'm using the InAppWebView flutter in order to do it, but I want to prevent the user to navigate to other pages when he clicks on a button inside the web view. Do I have to write some native code for iOS and Android to prevent the navigation?
Thanks

我是flutter的新手，我想在其他小部件之间放置一个web视图，为此我使用了InAppWebView Flutter，但我想防止用户在单击web视图中的按钮时导航到其他页面。我是否必须为iOS和安卓编写一些本机代码来阻止导航？谢谢
