What would you like to see?

Is there anything that you’d like to see on Caster.IO that we do not have already? If so, please comment here.


Hi Donn, I like to see some tutorials about some topics in Computer Science, like Algorithms, Data Structure, etc…

I am new to this website and I have been thinking to buy a yearly subscription. The lessons here are really top notch and would help me to solve many practical problems of mine.

But recently I have been assigned to a Flutter project and have been working on the framework heavily so I would like see some Flutter lesson addressing real world problem, for insurance, state management with bloC pattern.

@mohammedalaa545 thanks for the recommendation, we’ll consider some of these topics.

We have an instructor working on a Flutter course right now actually. Stay tuned … :slight_smile:


A course on Kotlin Coroutines would be really nice now that it’s stable. I hope you can put it together!


We are definitely working on that Albert. :slight_smile:

I would like to see in-depth course on
Dagger 2.
Code organization in an Android project.

Hi @donnfelker, I agree with @mohammedalaa545. Related to this topic the course could be also focused on an Android Dev job interview, like most commons questions, solving problems exercises (Algorithms…), Android framework fundamentals questions, etc…

I wasn’t a fan of the MVVM course that was created by Eric Maxwell. I felt like it was way below the quality of the other courses on Caster.io and I was really disappointed that the project chosen was to create a “tip calculator” app.

Is there any chance we could get another course with a different perspective of MVVM using relevant technologies such as Dagger2, Retrofit, RxJava/Coroutines, and other jet pack goodies? And please make the project more intriguing. I really enjoyed Joe Birch’s course on Clean Architecture and I’d love to see his take on the MVVM architecture.

Workmanager would be great to have a course on as well.

Also, I’d really enjoy a course on the Navigation component.

Better yet, have all of these included in a new MVVM course!

Any updates on the course on Coroutines @donnfelker ? Any ETA? Want to use them and will probably save me some time in learning how to use them :blush:

No update just yet. We had a problem with the course that we had. We’re working on a new one now.

Hey there, I’m surprised to hear this. In fact, this is the first negative criticism of the course I’ve heard (I’m not joking).

Making a project “more intriguing” is subjective, in my opinion. I might find a weight tracker for fitness intriguing while you find a project management app more your style. Its hard to find something that fits the bill for everyone. We try to ensure that we teach a concept as best possible, irregardless of the content.

That said, if you could change 3 things in this course, what would they be?

How should we break big project in modules based on feature.

I’d rather wait until 1.3 has been released. (Currently still at 1.3.0-M1). The reason for this is that the next release will (hopefully) include Kotlin Flows out of an experimental stage, so I would expect to see those in the course if released. The full support for cold streams will bring it closer to RxJava, so it would be a perfect time to start adopting coroutines in new Kotlin projects as a replacement of rx.

In terms of the course content, I’d like to see this implemented in MVVM architecture. A perfect candidate would be a multiple network call with transformation, local caching and some background operations on the way.

Hi. I’d like to see courses related to:

  1. A project that combines ViewModel, LiveData, Databinding and MVI.
  2. About modularization and dynamic features on Android.
  3. Unit Test with Robolectric 4 plus Espresso [using isolated Fragments/Activities]

Thank you for the great job you’re doing.

Hey, it would be nice a flutter course

Id like to see transcripts of the lesson…so i can quickly search the transcript to see if the video covers what I am interested in before watching the video

A new MVVM course with refreshed contents like Coroutines,Dagger, and Jetpack components will be a great addition to existing courses.


It’d be nice to have Certificates that we can post on our linkedin and resumes
