Build failure on Linux about hotkey_manager HOT 8 CLOSED

1. I reconfirmed that it works on main, but I need to add WidgetsFlutterBinding.ensureInitialized()
2. For hot reload, HotKeyManager.instance.unregisterAll() needs to be called;
3. No element error is fixed on macOS platform , Windows and Linux platform will fixed later.

void main() {
+  WidgetsFlutterBinding.ensureInitialized();

  final _hotkey = HotKey(
    KeyCode.keyF,
    modifiers: [KeyModifier.alt],
  );

+  HotKeyManager.instance.unregisterAll();
  HotKeyManager.instance.register(
    _hotkey,
    keyDownHandler: (hotKey) => print('keyDown'),
    keyUpHandler: (hotKey) => print('keyUp'),
  );

  runApp(MyApp());
}

New version seems to be working good in my brief testing. Thanks!

Love that you've made it feel simple and seamless, great work ❤️

On linux platform it depends on keybinder-3.0, You need to install it.

sudo apt-get install keybinder-3.0

from hotkey_manager.

Thanks! On Ubuntu-based distros this is:

sudo apt install libkeybinder-3.0-dev

Now it compiles correctly. 👍

On run however it throws an exception at instance.register():

  final _hotkey = HotKey(
    KeyCode.f6,
    modifiers: [KeyModifier.control, KeyModifier.shift],
  );

  await HotKeyManager.instance.register(
    _hotkey,
    keyDownHandler: (hotKey) {
      print('keyDown');
    },
    keyUpHandler: (hotKey) {
      print('keyUp');
    },
  );

Can you provide the code for flutter_hotkey_demo

from hotkey_manager.

Please don't use it in main function.

from hotkey_manager.

Alright, tried moving it out of main and it works some of the time. (Where do you recommend to initialize?)

"some of the time" because when it doesn't work; after hot reload I have seen it:

1. Fire the call back 3 times per press of the hotkey
2. Trigger an exception:

"No element"

Code is just from a new flutter project:

import 'dart:developer';

import 'package:flutter/material.dart';
import 'package:hotkey_manager/hotkey_manager.dart';

Future<void> main() async {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData(),
      home: const HomePage(),
    );
  }
}

Future<void> startHotkey() async {
  final _hotkey = HotKey(
    KeyCode.f6,
    modifiers: [KeyModifier.control, KeyModifier.shift],
  );

  await HotKeyManager.instance.register(
    _hotkey,
    keyDownHandler: (hotKey) => log('keyDown'),
    keyUpHandler: (hotKey) => log('keyUp'),
  );
}

class HomePage extends StatefulWidget {
  const HomePage({Key? key}) : super(key: key);

  @override
  State<HomePage> createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  @override
  void initState() {
    super.initState();
    startHotkey();
  }

  @override
  Widget build(BuildContext context) {
    return const Scaffold(
      body: Center(
        child: Text('Hotkey test'),
      ),
    );
  }
}

By the way, is there a specific reason this requires Flutter, and doesn't support a dart application? I could see it being very useful for that use case as well.
