Dependency Injection with Koin - Android Kotlin tutorial

Learn to use Koin for dependency injection in Kotlin and android projects. Koin is a great alternative to Dagger when you need to get up and running quickly.
Koin docs: insert-koin.io/

[@codinginflow]

You definitely have the best introduction of all coding channels

hahahaha.....

[@mattgraves3709]

I thought that was a mistake? ... :/ BTW Hello Florian

[@aykxt]

and probably the best outro too

[@Spham99]

LOL im deaddd xD

[@harishv4806]

Shit. I was reading docs and so many articles to get a grasp on Koin for hours. But here's a video which perfectly summarised everything with a simple example in 8 minutes. Thanks and PEASEEE!

[@Kukupuffs]

Thanks for simplifying this! I can’t tell u how many videos I’ve watched lol

[@youssefkhaled1189]

OMG, Finally someone explains a simple real example. Thank you so much!

[@mattgraves3709]

Great job! Just outstanding. In 8 minutes, we got everything we need to get started

[@kobowo]

That is a very pragmatic approach to understanding Koin. Thank you! Subscribed.

[@bas133]

Victor thank you so much! Such an excellent explanation with an approachable, but realistic example. I feel much more confident with koin than dagger.

[@kieran1990able]

This was super quick teaching and I understood in one go. So I subscribed you. Well done!!!

[@PrieyudhaAkaditaS]

Probably the best explanation of DI so far

[@felipesantiago3326]

simple and clear, congrats! 👏🏻

[@mattgraves3709]

I would add, man this just seems to make much more sense, now I hear people say Hilt is easier than Dagger2 etc, I never learned Dagger2 and Hilt was very unintuitive.
I was about to build my own when I got a project that needs this library's skill so here I am and loving it!
Very straightforward what you are doing.

[@damianperon6165]

AWESOMEEEE... finally a concise explanation... I've followed many tutorials without success (even Koin website)

[@deepakrattan2328]

Nicely explained.Thanks .Waiting for the next video.

[@theobencode7234]

You're welcome, working on the new video. Will be out soon :)

[@SankalpToons]

just 8 minutes to know koin , best video thank you

[@suhaswagre3396]

Great beginning for a course, thanks 🙏

[@andrii_gepbl4_from_deddom]

Thank you))
I've already used Dagger and Hilt and wanna try Koin. Nice lesson! Very easy to get in)

[@victormultiverse5799]

Tutorials should be like this video: fast and direct. Thanks a lot!

[@mehdit5783]

Explanations are insane ! Thanks !

[@taslimoseni2231]

+1 for the "See ya, PEEAAACCCEEE".

[@caranologi]

awesome, this example is easier to understand, thank you

[@samstoyroom]

You saved my day. Thank you!!

[@farkhodkh2760]

Cool exact demonstration of androud koin!

[@miladvarvaei]

thank you. it was very understandable for me. very clear

[@iftak01]

This is a really good tutorial man! Thanks.
Make a longer one with an sample app using koin mvvm retrofit etc. Thanks

[@MegaBezalel]

I recommend linking to part 2 in description

[@safionweb]

Great tutorial, subscribed :)

[@zachyang1041]

Great video!

[@arilson6024]

Good example for beginners 👏

[@AlphaZ96]

thank u ! best introduction

[@exXxkalibyR]

Very good explanation

[@rebekahoj]

Thank you.

[@mohamedebrahem1275]

Greate you amazing 👍

[@kisan_thapa]

Awesome!!!

[@fromthekeyboard1466]

You need to make more videos my friend !!!

[@jamesedwards9054]

What if you want to pass values into the student class that was called in MainActivity?

[@bitwisedevs469]

Just learn Dagger2 and moving now to Koin, so far this tutorial is really good and straight forward. I would say Dagger makes a really bad impression when learning DI on Android. Anyway, what is the disadvantage of Koin compare to Dagger as of this moment?

[@Spham99]

I aspire to be this good one day ...

[@marfinfadilah1591]

How do you restart the koin? is the koin does not work for dynamic function injection? such as this case,
"A user want to tell their school anytime and retrieve the student data with that provided school information" is it possible using this koin?

[@John-qt6qk]

Awesome at least I could get the hang of it lol

[@RaphaelCohen]

nice explanation. is there a reason you injected Student in your MainActivity in the onCreate? what if I want to inject them on init{} for example? can there be problems with that? Edit: never mind, I just saw your second video on lazy injection. really great examples, keep it simple.

[@gilong1311]

Hello, I have a question:
If I wanted to inject a BestFriend() class instead of a Friend() into the Student() class then would I just add BestFriend() in the module and change the parameter of the Student class to:
"class Student(course : SchoolCourse, bestFriend : BestFriend){...}"?

[@TheMikkelet]

hey so if I have a class with like 10 parameters, I would need to write constructor(get(),get(),get(),etc...)?

[@theobencode7234]

Yes you'd have to call get() so koin knows to retrieve your dependency. But realistically, how often do you have a class with 10 parameters?

[@TheMikkelet]

@@theobencode7234 well the problem I was thinking of was not so much how many, but rather that dependencies get added and removed from time to time! What I like about dagger is that I can just add a remove dependencies as I need them! I dont have to add/remove code in two places, if you get me?

[@theobencode7234]

@@TheMikkelet Yeah I totally get that view point, and we could have a discussion about service locator vs DI or Koin vs Dagger, but I think its important to understand both, and use what suits your needs. I'm also a fan of dagger and I made some videos on it, granted they are about 2yrs old. But hope that helps.

[@TheMikkelet]

@@theobencode7234 fair enough, I'll check those out? What is that rationale for koin then? Simplicity in other aspects?

[@theobencode7234]

@@TheMikkelet Yes, koin is simple to setup and easy to understand whereas Dagger has a very steep learning curve. If you've ever setup a dagger project you know the pain. I noticed this particularly when working on a team with junior devs and 80% of their questions were related to resolving Dagger issues. Hope that helps
