DAGGER2

Dagger 2 is a fully static dependency management framework for Java and Kotlin. It is the second version of the library of the same name created by Square and now officially supported by Google. Dagger 2 aims to enable the use of Dependency Injection in native Android languages. With it, you will have less clean code, weaker dependencies between objects, and simplified testing.

3 reasons to use Dagger 2 for your project
A simple solution for complex tasks

Dependency injection is a mandatory part of projects that will gradually scale and change. Without Dependency Injection, any changes to the program code will require a much larger amount of not only new code, but also reworking the old code, with calls to irrelevant data sources. Dagger 2 makes it possible to define configurations through an initializer, a set of classes that can be called where needed, rather than duplicated or fragmented every time they are needed. DI doesn't just reduce the amount of code, it also makes the application architecture clearer and more harmonious, while reducing the risk of breaking previously built relationships.

Code generation

Dagger 2 is the only full-stack dependency management framework for Java. It generates code that would otherwise have to be written manually. This ensures that everything is not only done correctly, but also as easily and efficiently as possible. Your developers will only need to run the tools and then check the correctness of the code generated by Dagger, which will definitely not contain accidental errors that a person could make by doing the same type of work manually again.

Optimization tools

Dagger 2 includes everything you need to implement Dependency Injection. Your developers will be able to create reusable application layers, implement linked logic, add annotations, and additional bindings. All of this and more is needed to ensure that your application maximizes performance without creating unnecessary layers of complex code.

Conclusions

Dagger 2 is one of the frameworks that facilitate project development and scaling. Dependencies can be implemented in other ways, but Dagger is the most popular comprehensive solution officially recommended by Google. It reduces the amount and complexity of code and provides centralized dependency management, which simplifies project development, testing, and growth.
