When something new on launchclub will be release? Your bloc instagram course was awesome. I need more

[abdimussa]

Thanks for the tutorial, but why do I feel like this is over complicating things than simplifying them

[Megapows]

Nice tutorial. What extension did you use to highlight error explanation at right side of the error line?

[dedykurniawan]

Riverpod vs bloc, which one would you choose?

[TYNEPUNK]

thanks, what to do if the freezed file just isnt generated?

[George-oruv]

This is the most outstanding of videos. Marcus does the freezer format that you use for classes have the same functionality as Equatable. Can I stop using Equatable and not have to worry about equality while using Freezed?

Hey, I'm interested on how you make bottom nav bar, do you mind to make one tutorial of it ?

[RizkyRamadhan-huof]
