🔍 Problem Faced:
In our Flutter app, we encountered a challenge where JavaScript alert boxes were not popping up as expected when using the flutter_webview package on iOS. This was a crucial feature for our app's user experience, especially for interactive web content.
👨💻 Solution Implemented:
To tackle this, extended the functionality of the app's AppDelegate class in Swift. The key was to use an @objc extension with FWFUIDelegate. This extension included custom methods to handle JavaScript alerts (runJavaScriptAlertPanelWithMessage) and confirms (runJavaScriptConfirmPanelWithMessage) using WKWebView.
🔧 Code Insight:
By leveraging Swift's powerful capabilities alongside Flutter, we were able to implement UIAlertController to display the necessary alerts and confirmations. The solution involved intricate use of view controller hierarchy to present alerts from the topmost view controller, ensuring a seamless and native user experience.
🙌 Result:
The app now smoothly displays web view alerts on iOS, enhancing the functionality and user interaction of our app.
