ServiceKey<T extends Object> class final

A typed name for distinguishing multiple implementations of the same type.

Most services can be resolved only by type:

final database = use<Database>();

Use a ServiceKey only when the same contract has multiple registrations:

const primaryDatabase = ServiceKey<Database>('primary');
const analyticsDatabase = ServiceKey<Database>('analytics');
