Providers_tracker

[Chralu]

ProvidersTracker keeps track of alive providers.

Usage in production is not recommended.

Howto use

Register the observer

import 'package:archethic_dapp_framework_flutter/archethic_dapp_framework_flutter.dart' as aedappfm;
runApp(
 ProviderScope(
   observers: [
     if (kDebugMode) aedappfm.ProvidersTracker(),
   ],
   child: const MyApp(),
 ),
;

Check all alive providers

In debug console, check ProvidersTracker content :

Command :

aedappfm.ProvidersTracker().aliveProviders

Result :

Set
[0] = AutoDisposeProvider (oracleServiceProvider:AutoDisposeProvider<OracleService>#2d1c8)
[1] = AutoDisposeAsyncNotifierProviderImpl (_archethicOracleUCONotifierProvider:AutoDisposeAsyncNotifierProviderImpl<_ArchethicOracleUCONotifier, ArchethicOracleUCO>#4aa30)
[2] = AutoDisposeProvider (apiServiceProvider:AutoDisposeProvider<ApiService>#e4552)

Filter and READ providers

In debug console :

Command :

aedappfm.ProvidersTracker().byName('oracle').read

Result :

Set
[0] = AutoDisposeProvider (oracleServiceProvider:AutoDisposeProvider<OracleService>#2d1c8)
[1] = AutoDisposeAsyncNotifierProviderImpl (_archethicOracleUCONotifierProvider:AutoDisposeAsyncNotifierProviderImpl<_ArchethicOracleUCONotifier, ArchethicOracleUCO>#4aa30)

Filter and WATCH providers

In debug console :

Command :

// watch returns a stream. Here we just log the number of providers whose name matches 'oracle'
aedappfm.ProvidersTracker().byName('oracle').watch.forEach((providers) => print('>>> Oracle : ${providers.length}'))

Result :

Each time the alive providers matching 'oracle' changes, we have a log like this :

>>> Oracle : 2
