·2026.11.11 15:41
Key point
Hilt Custom Component regenerates the dependency tree upon login state changes to manage object lifecycles per user.
Details
- Hilt Custom Component must be located in the hierarchy below SingletonComponent and cannot be inserted between existing Hilt components
- The structure is implemented to regenerate AuthUserComponent when the logged-in user changes, injecting Repository and DataSource objects specific to that user
- Access Custom Component via EntryPoint, and use EntryPointAccessor to ensure type safety
- AuthUserComponentManager subscribes to UserAuthSession to automatically regenerate the component when login/logout events occur
- Using Custom Component has the drawbacks of increased dependency graph complexity and difficulty integrating with external libraries
- The sample app is available in the HiltCustomComponentSample repository on GitHub
