Are you sure you have already searched for the same problem?
Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!
If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.
In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE]
or ios WKWebView [MY ERROR HERE]
keywords.
Following these steps can save you, me, and other people a lot of time, thanks!
I have the same problem
Environment
Description
For iOS device that method is working fine but for Android that function is not even triggered which is causing issue to set the height of email after height changed on UI.
Code: class _EmailViewerState extends State {
late InAppWebViewController _webViewController;
late String jsContent;
late String loadingBase64;
@override Widget build(BuildContext context) { return InAppWebView( onContentSizeChanged: (controller, oldContentSize, newContentSize) { widget.heightChange(newContentSize.height); }, onWebViewCreated: (controller) { _webViewController = controller; }, onConsoleMessage: (c, m) { print(m.toString()); }, onLoadStop: (controller, url) async { await loadJavaScript(); _loading(); for (Attachments image in widget.attachments.where((element) => element.inline == true)) { _downloadFile(image); } _imageClickListener(); }, initialSettings: InAppWebViewSettings( javaScriptEnabled: true, loadWithOverviewMode: false, useWideViewPort: false, alwaysBounceHorizontal: true, blockNetworkImage: false, disallowOverScroll: true, allowContentAccess: true, supportZoom: true, blockNetworkLoads: false, loadsImagesAutomatically: true, enableViewportScale: true, alwaysBounceVertical: false), initialData: InAppWebViewInitialData(data: widget.body), ); }
Future loadJavaScript() async {
jsContent = await rootBundle.loadString('assets/js/viewer.js');
final ByteData data =
await rootBundle.load('assets/images/gif/loading.gif');
loadingBase64 = base64Encode(data.buffer.asUint8List());
}
void _downloadFile(Attachments attachment) { if ((attachment.embedded == true || attachment.inline == true) && (attachment.contentId?.isNotEmpty == true)) { FileManager.imageDownloader ?.base64ImageDownload( attachment.id, attachment.filename ?? '${attachment.id}.png}') .then((value) { final String contentId = attachment.contentId!.replaceAll('>', '').replaceAll('<', ''); _webViewController.evaluateJavascript(source: """ $jsContent
}
void _loading() { print(loadingBase64); _webViewController.evaluateJavascript(source: """ $jsContent
}
void _imageClickListener() async { _webViewController.addJavaScriptHandler( handlerName: 'onImageClick', callback: (arguments) { if (arguments.firstOrNull != null) { final Attachments? attachment = widget.attachments.firstWhereOrNull( (element) => element.contentId?.contains(arguments.firstOrNull ?? '') == true); if (attachment != null) { FileManager.imageDownloader ?.downloadInlineImage(attachment.id, attachment.filename ?? '${attachment.id}.png}') .then((value) => OpenFile.open(value)); } } }, ); _webViewController.evaluateJavascript(source: """ document.querySelectorAll('img').forEach(img => { img.addEventListener('click', function(event) { var dataCid = img.getAttribute('data-cid'); if (dataCid) { window.flutter_inappwebview.callHandler('onImageClick', dataCid); } }); }); """); } }
