Dio

YAML

stackchain:
  network: dio

Generated client

Core networking under lib/core/network/ includes a Dio-based API client with:

Interceptor	Role
Auth	Attaches session credentials
Logger	pretty_dio_logger
Error	Maps failures consistently
Retry	Retries while preserving auth headers
Unauthorized	Clears session on 401

Repository pattern

Feature remote datasources call the shared client; repository implementations sit in data/repositories and fulfill domain contracts.
