Thank you 👍

[@SurajKumar-ge1um]

A very great tutorial bhai!! Keep it up!!
However, I have a question, agar Consumers ko @Inject karke annotate kia jata h(Consumers as it means it will be consuming the objects), to sabse pehle humne UserRegistrationService Class par @Inject kyu kia in the context ki UserRegistrationService ka object banana h? Is Class par @Inject Annotate karne ka matlab to ye hua ki isko object mil rha hoga and ideally, Inject to MainActivity ko hona chahiye kyunki vo consumer h?

[@rpitpatel1004]

Great Tutorial Sir, Can you please provide a starter project so we can work on it as we go through the playlist? Thank you🙏

you can refer the new series or you can refer the github of this repo with MVVM and Retrofit - github.com/CheezyCode/DaggerMVVM

your videos are amazing but my DaggerUserRegistrationComponent class is not generated..

[@sumitsingh6533]

UserRegistrionComponent not make my Class why...?

[@vijaykumar-jm1fq]

sir i am following your video, i am facing problem in this time that is kapt in dependency showing error and when i use annotation dependency instead of kapt dependency it works fine but getting problem in when i call this class "DaggerUserRegistrationServices". sir help me what should i do now?

[@shashanksp9168]

+1

[@rizwanahmedkhan237]

implementation 'com.google.dagger:dagger:2.45'
kapt 'com.google.dagger:dagger-android-processor:2.45'
kapt 'com.google.dagger:dagger-compiler:2.45'
Use this dependency for dagger and kapt , it fixed my problem

[@yashraghuvanshi6449]

Try this whith implementation (" ") instead of kept(" ")

[@Vk-bw9cv]

annotationProcessor 'com.google.dagger:dagger-compiler:2.40.5'

[@Usmankhan-yr3dl]

even mvvm architecture was easy to learn but dependancy injection is hard to understand , complex topic It is

[@CheezyCode]

It is easy...just think before you jump to another video...why I did it the way I did it...what's the benefit do we get by writing code like this - just think for a moment...try to write down your problems, your thoughts on each concept. It will start making sense..
Still stuck - write down in comments for me...I will help you out

[@haider-u9s]

need video on kmm

[@sachinsharma7804]

So using inject dagger knows what kind of object to build. Is that right?

[@CheezyCode]

Using Inject helps dagger to build that particular object. It is a way to tell Dagger that if you need X object - use this constructor annotated with @Inject.
One more use case of @Inject will be covered in next video.

Not sure...need to check - you can refer the codebase on GitHub.com /cheezycode / dagger examples

[@amarnathbaitha979]

@Rosan Nepal
Please use this below code, I was facing same issue. Now it is working fine.
plugins {
id 'com.android.application'
id 'org.jetbrains.kotlin.android'
id 'kotlin-kapt'
}
implementation 'com.google.dagger:dagger:2.25.3'
kapt 'com.google.dagger:dagger-android-processor:2.25.3'
kapt 'com.google.dagger:dagger-compiler:2.25.3'

[@albedo9617]

You probably don't need this anymore so commenting for other people, replace the kapt 'com.google.dagger....' with annotationProcessor 'com.google.dagger....' That fixed it for me.
