Here is the problem.
-
Create a fresh flutter app - the one that increments the counter.
-
In the initState I override the mouse left click context menu.
-
Create a simple context menu.
-
In the build method add listener that shows that context menu when right mouse button is clicked.
-
I try to run the app in chrome
flutter run -d chrome --web-port 5000 --web-renderer html
In debug mode everything works fine.
However in profile mode or release mode, the context menu is displayed but when I mouse-click anywhere, the page stops responding completely.
Here is how I run it in profile mode:
flutter run -d chrome --web-port 5000 --web-renderer html --profile
Here is full code:
import 'package:universal_html/html.dart';
import 'dart:ui';
import 'package:flutter/gestures.dart';
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
int _counter = 0;
@override
void initState() {
super.initState();
document.onContextMenu.listen((event) => event.preventDefault());
}
void _incrementCounter() {
setState(() {
_counter++;
});
}
Future<void> _onPointerDown(PointerDownEvent event) async {
// Check if right mouse button clicked
if (event.kind == PointerDeviceKind.mouse &&
event.buttons == kSecondaryMouseButton) {
final overlay =
Overlay.of(context)!.context.findRenderObject() as RenderBox;
final menuItem = await showMenu<int>(
color: Colors.grey.shade100,

RoundedRectangleBorder(borderRadius: BorderRadius.circular(10)),

// Check if menu item clicked
switch (menuItem) {

break;

{}
break;
case 3: //Case for 'Clear'

break;

{}
break;
}
}
}
@override

Here is flutter doctor output:

I have absolutely no idea what is going on here. If anyone could help me it would be greatly appreciated!
I also tried creating a build and uploading to a web server - same thing, the page stops responding.
