Observer Method Design Pattern
The observer structure defines one to many dependencies between objects, so when one object changes its state, all its dependents are automatically notified and updated. This is useful for scheduling distributed events.
For Example:
In the reports app, many features (Observers) such as the title widget, the report feed view, and the notification provider (Themes) can subscribe to updates when new information arrives. The observer model ensures that they are created all registered parts report, and accordingly You can update it.
Design Patterns for Mobile Development
Design patterns are reusable solutions to common software development problems. They have had a significant impact on software development, including mobile app development. The implementation of mobile apps has established some proven models and standards to overcome the challenges and limitations of mobile app development.
Most mobile applications were built with low code and were not based on architecture. Mobile app development with the right design patterns can effectively integrate user interfaces with data models and business logic. This will affect the quality of your source code.
Important Topics for Mobile Development Design Patterns

- Dependency Injection (DI)
- Adapter
- Strategy
- Composite
- Conclusion
There are very few architectural design patterns available for mobile development.
