Description
Expected behavior: Widget with webview should be visible.
Current behavior: Widget with webview is not visible on Android after upgrade plugin to v.6.0.0, worked fine on v.5.8.0 and is working fine on iOS in both versions.
Steps to reproduce
- Widget code:
Widget build(BuildContext context) {
final html = """
<html lang="pl">
<meta name="viewport" content="width=100, initial-scale=1, user-scalable=no">
<style>iframe {max-width:100%; border: 0; overflow:hidden;} </style>
<style>html,body { margin: 0; } </style>
<body>
<div class="container" id="_flutter_target_do_not_delete">$replacedHtml</div>
<script>
function outputsize() {
if (typeof window.flutter_inappwebview !== "undefined" && typeof window.flutter_inappwebview.callHandler !== "undefined")
window.flutter_inappwebview.callHandler('newHeight', document.getElementById("_flutter_target_do_not_delete").firstChild.offsetHeight);
}
new ResizeObserver(outputsize).observe(_flutter_target_do_not_delete)
</script>
</body>
</html>
""";
final Widget webviewWidget = SizedBox(
height: height,
width: double.infinity,
child: InAppWebView(
initialData: InAppWebViewInitialData(data: html),
initialSettings: InAppWebViewSettings(
transparentBackground: true,
supportZoom: false,
disableHorizontalScroll: true,
disableVerticalScroll: true,
),
onWebViewCreated: (InAppWebViewController controller) {
controller.addJavaScriptHandler(
handlerName: 'newHeight',
callback: (List<dynamic> arguments) async {
final contentHeight = await controller.getContentHeight();
final zoomScale = await controller.getZoomScale();
final htmlHeight = contentHeight!.toDouble() * zoomScale!;
final htmlHeightFixed =
double.parse(htmlHeight.toStringAsFixed(2));
if (htmlHeightFixed == 0.0) {
return;
}
final int? innerHeight;
if (arguments.isNotEmpty) {
innerHeight = arguments[0] as int;
} else {
innerHeight = await controller.getContentHeight();
}
if (mounted) {
setState(
() =>
height = (innerHeight != null &&
innerHeight.toDouble() > htmlHeightFixed)
? innerHeight.toDouble()
: htmlHeightFixed,
);
}
},
);
},
),
);
if (widget.disablePadding ?? false) {
return webviewWidget;
}
return Column(
children: [
TabletMargins(
mobilePadding: AppSpacing.lg,
child: webviewWidget,
),
const SizedBox(),
],
);
