health_forge 0.1.1

Flutter toolkit aggregating health data from HealthKit, Health Connect, Oura, and Strava into a unified model with conflict resolution and local caching.

health_forge

Flutter client for Health Forge — aggregate health data from multiple providers (HealthKit, Health Connect, Oura, Strava) into a unified data model with conflict resolution and local caching.

Built on health_forge_core (pure Dart data model + merge engine).

Features

• Provider registry — register any HealthProvider implementation and the client discovers its capabilities
• Auth orchestration — authorize/deauthorize/checkAll across all registered providers
• Fluent query API — build cross-provider queries by MetricType + TimeRange, pick a merge strategy per query
• Caching — InMemoryCacheManager for tests, DriftCacheManager (SQLite) for production
• Sync manager — coordinate incremental syncs with deduplication and metadata tracking
• Secure token storage — TokenStore wraps flutter_secure_storage for OAuth tokens

final forge = HealthForgeClient();

forge.use(AppleHealthProvider());
forge.use(GhcHealthProvider());

await forge.auth.authorizeAll();

final builder = forge.query()
  ..forMetrics([MetricType.heartRate, MetricType.sleepSession])
  ..inRange(TimeRange(
    start: DateTime.now().subtract(const Duration(days: 7)),
    end: DateTime.now(),
  ));

final executor = QueryExecutor(
  registry: forge.registry,
  mergeEngine: MergeEngine(config: const MergeConfig()),
);
final result = await executor.execute(builder.build());

for (final record in result.records) {
  print('${record.provider}: ${record.providerRecordType}');
}
