Dependency injection from zero to hero with Koin
summary
Claims a pragmatic DI that replaces Dagger with concrete migration steps and Android adapters: shows a Thermosyphon coffee‑maker demo rebuilt with Koin and a path to migrate from Dagger component-by-component. Describes Android extensions, viewModel constructor injection, lifecycle scope API and test tooling with check modules in JUnit. Reports a rewrite that drops a 140ms lookup to about 450 definitions in ~1ms for bulk resolution. Shows runnable code, Gradle dependency names, and the startKoin/start function changes.
