Great talk :) One question comes to my mind: isn't using BlocListener kind of breaking the rule of decoupling the UI from business logic? If we want to do some side action in response to state change, doing so in a UI code (such as the BlocListener widget used in the build method of some StatelessWidgget) is meh. Wouldn't doing those kind of actions fit better inside the bloc itself so that we can test that easly and truly separate UI from business logic? (such as showing a snackbar and what not, that is business logic imo)

Amazing content! I am a bigger fan of bloc and Flutter in general after this xD PS- Am I the only one to notice that hydrated_bloc example started incrementing with 0 ( 37:55 ) and not with the state it maintained ( 3 in this example) ?

Bloc isn't that hard nor is it verbose for a large app... If you've learned Provider, you're comfortable using Bloc by Felix for larger applications. Having a counter app tutorial doesn't leverage the full features of Bloc itself. Having too complex tutorial like Todos fits for the job, but beginners will have a hard time following it due to huge chunks of code to be followed. Just to take note. State Management solves particular usecase. Bloc + Provider + Abstraction for me is the best combination.

When to use Equatable with Bloc? I see a lot of people using Equatable with Bloc and I am not sure what it does actually

@aaulia 4 жыл бұрын

Equatable is basically a poor man data class. It override Type's equality operation so that instead of comparing the instance reference, it compares the content instead. So two separate instance of the same Type is equal if both have the same content/data. It's okay-ish, and it works, and less hassle to setup. But personally, coming from Kotlin, I'd rather use something like built_value or freezed.

@Flutter Europe Hello, Bloc is cool but GetX is more efficent in my oppinion. GetX has State simple/reactive management(without codegen), route Management and Dependencies management 3-IN-1. This is a hidden and powerfull tool that nobody talks about. Some conten about would be great.
