DirectInstantiationAnalyzer class

Analyzer that enforces dependency injection by flagging direct class instantiations.

This rule detects violations where classes are instantiated directly instead of using dependency injection. Exclusions are configured centrally via LinterConfig and include:

  • Classes from allowed packages (Flutter, Supabase, etc.)
  • Classes extending ignored base classes (Equatable, Module, Event, etc.)
  • Instantiations in specific contexts (const, factory, Module binds methods)
  • Safe value objects from whitelisted packages

Configuration should be provided at analyzer creation time. If no config is provided, defaults are used.
