import 'package:flutter/material.dart';

import 'package:xunil_blue_connect/xunil_blue_connect.dart';


class MainBody extends StatefulWidget {

const MainBody({Key? key}) : super(key: key);

@override
State<MainBody> createState() => _BodyState();

}

class _BodyState extends State<MainBody> {

bool _isBluetoothAvailable = false;

@override
void initState() {

    super.initState();
    
    initBlueToothAvailable();
    
}

//if bluetooth return null, it means the device doesn't support bluetooth

Future<void> initBlueToothAvailable() async {

    bool isBluetoothAvailable;
    
    isBluetoothAvailable = await XunilBlueConnect.isBluetoothAvailable();
    
    if (!mounted) return;
    
    setState(() {
    
      _isBluetoothAvailable = isBluetoothAvailable;
    
    });

}

  
@override
Widget build(BuildContext context) {
    return Center(
        child: SizedBox(
            height: MediaQuery.of(context).size.height * 0.33,
            
            child: Column(
                mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                crossAxisAlignment: CrossAxisAlignment.center,
                children: [
                    Text('Bluetooth is ${_isBluetoothAvailable ? 'ON' : 'OFF'}'),
                    ElevatedButton(
                    onPressed: () async {
                    var isBlue = await XunilBlueConnect.isBluetoothAvailable();
                      setState(() {
                          _isBluetoothAvailable = isBlue;
                      });
                    },
                    child: const Text('Check'),
                    )
