DataSource
a DataSource handles interactions with external data sources like databases or APIs. It abstracts away the details of data access and provides a simple interface for the rest of the application.
This separation of concerns keeps the inner layers focused on business logic and ensures flexibility in adapting to changes in data sources.
getPlatform
This code snippet defines an expect class named DataSource, which serves as an abstraction for a data source in a Kotlin Multiplatform project.
It declares a method getPlatform() that returns a Platform object.
The implementation of this method is left abstract, indicated by the absence of a body in the declaration.
This allows platform-specific implementations to be provided in platform-specific modules using the actual keyword.
Overall, the expect keyword defines a platform-independent interface or declaration that must be implemented by platform-specific code.
