How to Get DeviceId in Flutter ?

• Install device_id Package and put in dependencies in pubspec.yaml file. As like blelow.

dependencies:
  flutter:
    sdk: flutter
  device_id: ^0.2.0

• Get the dependencies by command pub get.
• Now you are ready to use this plugin.
• First of all define variable DeviceId in file where you want to use device_id as like below

String deviceID;

• Now make method that will return you device_id as string same like below

void getDeviceID() async {
  String deviceId = await DeviceId.getID;
  deviceID = 'Device ID is $deviceId';
  print('Device ID is $deviceId');
}

• Now, Trigger this method in initState so you will get device_id when initstate will build.

@override
void initState() {
  // TODO: implement initState
  super.initState();
  getDeviceID();
}

• That’s it. Now you can use Device_id any where, also you can add DeviceId in setState so it can use anywhere I am pasting my full source code here.

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

class GetDeviceId extends StatefulWidget {
  @override
  _GetDeviceIdState createState() => _GetDeviceIdState();
}

class _GetDeviceIdState extends State<GetDeviceId> {
  @override
  String deviceID;

  void getDeviceID() async {
    String deviceId = await DeviceId.getID;
    deviceID = 'Device ID is $deviceId';
    print('Device ID is $deviceId');
  }

  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    getDeviceID();
  }

  @override
  Widget build(BuildContext context) {
    getDeviceID();
    return MaterialApp(
      home: Scaffold(
        appBar: new AppBar(
          title: const Text('How to Get DeviceId'),
        ),
        body: Center(
          child: Text('$deviceID'),
        ),
      ),
    );
