This is a wrapper for the raw keyboard listener made to simplify intercept external keyboard button press.
To install the package use the latest:
keyboard_manager : ^0.2.0
To use this plugin simply wrap the Scaffold of your root widget with the KeyboardManager widget.
In your initState instantiate a Keyboard with what you want to do when the relative keys are pressed.
import 'package:flutter/material.dart';
import 'package:keyboard_manager/keyboard_manager.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
@override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
Keyboard _keyboard;
@override
void initState() {
_keyboard = new Keyboard(
left: (){
print("left key pressed");
},
right: (){
print("right key pressed");
}
);
super.initState();
}
@override
Widget build(BuildContext context) {
return MaterialApp(
home: KeyboardManager(
keyboard: _keyboard,
autofocus: true,
child: Scaffold(
appBar: AppBar(
title: const Text('Keyboard manager example'),
),
body: Center(
child: Text('I am listening to keyboard events'),
),
),
),
);
}
}
