feature_flags_toggly_disk

On-disk (plain JSON file) 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 as JSON files under the app documents directory so flags survive app restarts and remain available offline.

This backend is not encrypted. If cached payloads must be protected at rest, use feature_flags_toggly_secure_storage.

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

Install

dependencies:
  feature_flags_toggly: ^1.2.0
  feature_flags_toggly_disk: ^0.1.0

Usage

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

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

Provide a custom directory if you don't want the default app documents location:

DiskCacheProvider(directory: myDirectory);
