WebviewScaffold alway on top

There is no way to display a FloatingActionButton over the webview. The button shows one sec then disapper. Stack seems not working. The WebviewScaffold remains always on top

Scaffold(
body: SafeArea(child: WebviewScaffold(
url: "http://192.168.4.100:8080",
withJavascript: true,
javascriptChannels: [
_alertJavascriptChannel(context),
].toSet(),
),),
floatingActionButton: Row(
mainAxisAlignment: MainAxisAlignment.end,
children: [
Visibility(
visible: _isFlashButtonOn,
child: FloatingActionButton(
onPressed: _toggleFlash,
tooltip: 'Toggle Flash',
backgroundColor: Colors.purple,
child: Icon(Icons.lightbulb_outline),
),),
SizedBox(
width: 10,
),
Visibility(
visible: _isButtonOn,
child: FloatingActionButton(
onPressed: _readBarcode,
tooltip: 'Scan Barcode',
child: Icon(Icons.camera_alt),
),),
],
),
),

No source file or test is named. Start by reproducing the provided Scaffold and WebviewScaffold example, then trace the plugin's WebView layering behavior on the affected platform. Done means the FloatingActionButton remains visible and usable over the WebView instead of disappearing after a second.
