Architecture & Design Patterns

Federated Plugins

Implement federated plugins to split a plugin's API across multiple packages, allowing independent teams to build platform-specific implementations. Structure federated plugins into three distinct components:

1. App-facing interface: The primary package users depend on. It exports the public API.
2. Platform interface: The package defining the common interface that all platform implementations must implement.
3. Platform implementations: Independent packages containing platform-specific code (e.g., my_plugin_android, my_plugin_windows).
