feature_flags_toggly_isar

Isar database persistence backend for the Toggly Flutter SDK (feature_flags_toggly).

The Toggly SDK is memory-only by default. Add this package to persist feature flags, variant definitions, and JWKS in an Isar database so flags survive app restarts and remain available offline.

This package uses the community-maintained isar_community fork (the original isar package is no longer maintained). It is API-compatible with Isar v3.

Offline restart also requires a stable identity passed to Toggly.init / Toggly.setIdentity.

Install

dependencies:
  feature_flags_toggly: ^1.2.0
  feature_flags_toggly_isar: ^0.1.0

Usage

Opening Isar is asynchronous, so create the provider with IsarCacheProvider.open() before initializing Toggly:

import 'package:feature_flags_toggly/feature_flags_toggly.dart';
import 'package:feature_flags_toggly_isar/feature_flags_toggly_isar.dart';

final cacheProvider = await IsarCacheProvider.open();

await Toggly.init(
  appKey: '<your-app-key>',
  environment: 'Production',
  identity: currentUserId,
  config: TogglyConfig(
    cacheProvider: cacheProvider,
  ),
);

By default the Isar instance is created under the app documents directory; pass directory: to open() to choose another location.
