firebase_instance_id

a flutter plugin to retrieve the firebase app instance id# device_unlock

how does it work

app instance id is an unique identifier for an instance of the app. in other words, each user/installation has such a value. it is a 32-character hex number like a12bc3d456789efabc123456a8a5de56.

obs.: the project should have firebase configured for this plugin to work.

sample code

import 'package:firebase_instance_id/firebase_instance_id.dart';

var instanceid = await firebaseinstanceid.appinstanceid ?? 'unknown installation id';
