Conversation
Extracts IcebergRestCatalog, its exceptions and the table and namespace types out of storage_client and into a new iceberg package, mirroring the split between storage-js and iceberg-js. storage_client depends on it and re-exports the whole surface, so the public API of storage_client, supabase and supabase_flutter is unchanged and analyticsCatalog() still returns a catalog. Only imports of the private src paths break.

📝 WalkthroughWalkthroughThe pull request extracts the Apache Iceberg REST Catalog client into a standalone Dart package. It adds models, exceptions, documentation, an example, package metadata, Storage re-exports, workspace registration, and workflow coverage. ChangesIceberg package extraction
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The package move preserves supported public imports, but migration guidance for private imports is incomplete and unexpected catalog error payloads may produce a parsing exception instead of the original API error. The PR is mergeable with owner awareness and follow-up on these bounded issues. Sequence Diagram(s)sequenceDiagram

| ### The Iceberg catalog moved to its own package | ||
|
|
||
| `IcebergRestCatalog`, the exceptions above and the table and namespace types now live in | ||
| `iceberg`, mirroring the split between `storage-js` and `iceberg-js`. `storage_client` | ||
| depends on it and re-exports the whole surface, so importing | ||
| `package:storage_client/storage_client.dart` or `package:supabase_flutter/supabase_flutter.dart` | ||
| keeps working unchanged, and `storage.analyticsCatalog()` is still how you get a catalog for an | ||
| analytics bucket. | ||
|
|
||
| Depend on `iceberg` directly to talk to an Iceberg REST Catalog without the rest of Storage: | ||
|
|
||
| ```dart | ||
| final catalog = IcebergRestCatalog( | ||
| baseUrl: 'https://example.com/iceberg', | ||
| headers: {'Authorization': 'Bearer $token'}, | ||
| warehouse: 'my-warehouse', | ||
| ); | ||

Document the private-import migration explicitly.
The section does not state that imports such as package:storage_client/src/iceberg/... must change. Add the replacement import, package:iceberg/iceberg.dart, and state that direct users must add iceberg as a dependency. Keep the existing storage_client and supabase_flutter import paths documented as supported.
The PR objective states that direct imports of private storage_client/src/iceberg paths are no longer supported.

Harden the error-payload casts.
error['code'] as int?throws aTypeErrorwhen the catalog sends a JSON number that decodes todouble. The cast ofbody['error']toMap<String, dynamic>also throws when the decoded map is not string-keyed, because the guard only checksis Map. Both throws occur while building the error, so the original API failure is replaced by an opaque cast error.Use type tests instead of casts.
🛡️ Proposed fix for the payload parsing
- if (body is Map<String, dynamic> && body['error'] is Map) { - final error = body['error'] as Map<String, dynamic>; - message = (error['message'] as String?) ?? message; - errorCode = error['type'] as String?; - code = error['code'] as int?; - } + if (body is Map && body['error'] is Map) { + final error = body['error'] as Map; + final rawMessage = error['message']; + if (rawMessage is String) message = rawMessage; + final rawType = error['type']; + if (rawType is String) errorCode = rawType; + final rawCode = error['code']; + if (rawCode is num) code = rawCode.toInt(); + }📝 Committable suggestion

What
Extracts the Apache Iceberg REST Catalog client out of
storage_clientand into a newicebergpackage, mirroring the split betweenstorage-jsandiceberg-js, wherestorage-jstakesiceberg-jsas a plain dependency.storage_client/lib/src/iceberg/*.darticeberg/lib/src/*.dartstorage_client/test/iceberg_test.darticeberg/test/iceberg_test.dartThe moved surface is
IcebergRestCatalog, the sealedIcebergExceptionhierarchy, and the table and namespace types. Everything is a pure move, no behaviour changed.Why
The catalog is a generic Iceberg REST Catalog client: it only needs a
baseUrland headers, and nothing in it reaches into Storage. As its own package it can be depended on without the rest of Storage, and it gets its own version line and changelog rather than having Iceberg spec churn interleaved with file and vector bucket releases.Compatibility
The public API is unchanged.
storage_clientdepends onicebergand re-exports the whole library, sopackage:storage_client/storage_client.dart,package:supabase/supabase.dartandpackage:supabase_flutter/supabase_flutter.dartstill resolve every Iceberg symbol, andstorage.analyticsCatalog()still returns anIcebergRestCatalog.
