ds_storage_base 0.0.1

Base storage interfaces and manager for DartStream.

DartStream Storage (ds_storage_base)

Base storage interfaces and provider registration for DartStream.

OSS Provider Policy

The open-source framework only ships adapters for the most battle-tested and widely adopted storage backends. Vendor-specific adapters that are not strongly maintained in Dart are reserved for the SaaS edition unless community demand justifies OSS support.

Supported OSS Providers (Lean List)

• S3-Compatible Storage (AWS S3, MinIO, Cloudflare R2, DigitalOcean Spaces)
• Google Cloud Storage (GCS)

Adapters for these providers may live as separate packages; if a provider package is not present in this repo, it is considered planned or maintained in a dedicated repo.

Vendor Profiles (Docs-Only)

These are recommended stacks for teams that prefer a cloud-vendor mental model. They are not provider packages and do not appear in the registry.

• AWS profile
  • S3 -> ds_storage_aws
• GCP profile
  • Cloud Storage -> ds_storage_gcp
• Azure profile
  • Azure Blob Storage (not in OSS)

Not in OSS (SaaS or community-driven)

• Azure Blob Storage
• Backblaze B2 (native SDK)

Provider Contract

Providers implement the shared interface from ds_storage_base and are registered with DSStorageManager.

If you plan to publish a provider, ensure it includes:

• pubspec.yaml with sdk: ^3.10.8
• LICENSE (DartStream standard)
• CHANGELOG.md
• manifest.yaml for registry/discovery
