Very well done Simon! you have a weird way of making everything so easy! thank you for your efforts 👏

[@galaxies_dev]

My pleasure!

[@ferrad1]

I love it ! I just subscribed to the channel ! Thank you sir

[@galaxies_dev]

Welcome aboard!

I having a problem with zustand. After the state is changed, it doesn't re-render the component. Does anyone have the experience in this issue?

[@SubhranshuChoudhury]

Thanks, it really helped :)

[@AGUNGKAYA]

Sir, have you made a video on how to make "Pay as you like" like the one in website of "Elementary OS"? Then go to payment section. I want to implement such thing on my website. Thank you very much

[@LeonardoSilva-yj9lg]

Por que não incluir mmkv nos pacotes expo ?

[@angeromeogouebi2948]

mmkv react native doesn't work on my windows 11 pc, can you help me

[@mishen-thakshana]

Thanks for this. Will you be coming live soon?

[@galaxies_dev]

Will try!

[@eltondeveloper1159]

Hi Guy. Is it possble you create a todo with zustand and express REST API. In KZbin I not found this tutorial anyway. Thanks!

[@galaxies_dev]

Sure, might be a cool tutorial indeed!

[@kennyfully88]

Thanks for introducing Zustand to us! I was making some business decisions for the future and unfortunately, Flutter didn't live up to its expectations for me. However I do have React Native apps shipped... But now I'm highly considering building something med size. BTW Joutai 状態 does mean state like you said, but you pronouned it wrong. Try using the American English J sound instead of the J sound from your language.

[@galaxies_dev]

Oh yeah that sounds better for Jotai :D And happy to share Zustand - it's awesome how simple yet great it works!

started a new react native project, Async storage is slow so I decided to switch to react-native-mmkv, it doesn't work with expo go so I changed the project to a development build and did 'expo prebuild" like the react-native-mmkv doc said, I installed the development build version on my mobile phone and ever since then, my app wont work at all, it keeps throwing this error invariant violation: "main" has not been registered. this can happen if: * metro (the local dev server) is run from the wrong folder. check if metro is running, stop it and restart it in the current project. * a module failed to load due to an error and appregistry.registercomponent wasn't called., js engine: hermes I have done expo prebuild --clean, deleted and reinstalled my node modules, created and development build, updated my packages, started another project, they all don't seem to work, as long as react-native-mmkv is there, it doesn't work. please I need a fix for this, I've google searched everywhere, nothing.

[@galaxies_dev]

You also need to run the dev server locally after installing the app, or simply run "npx expo run:ios" to have it all in one!

[@call_me_rusker]

how did you achieve this "@/XXXX/XXX" alia path without "babel-plugin-module-resolver" package, I fllow the video, the setting doesn't work🤔

[@call_me_rusker]

never mind, I change the"./*" to "src/*", it works

[@hewr_srood]

Do you prefer Zustand over Recoil?

[@galaxies_dev]

Zustand!

[@emirhanpakyardm9142]

I don't know why but MMKV doesn't support Expo Go. So I can't use it

[@galaxies_dev]

Why are you bound to Expo Go? That's limiting yourself!

[@emirhanpakyardm9142]

@@galaxies_dev i like seeing the app through my phone, also emulators tires my pc

[@paulh6933]

sometimes it sounds like chustand, others it sounds like zuustand, maybe spelling it phonetically would help me

[@galaxies_dev]

I guess it would be like "tsushtand" :D

[@tejasbhatt1820]

In one video you said yo don't like react native and flutter then why now?

[@kennyfully88]

I will tell you my Answer from experience. Flutter does promise a lot and does a lot out of the box. However, Flutter projects are such a pain to keep business logic together ans organized. Another problem that came to me was that Flutter, unlike React Native, doesn't have a true Zindex api. This brought me a lot of problems were I had to end up making a top layer just to overlay and do specific things. And oh my goodness.... Refactoring Flutter code on large scale is a different job in itself, which takes someone with a patience of steel. At First, I moved to Flutter because of the excellent Animation API out of the box and all the hype that was in my dev group, but I ended up finding out the painful way that Flutter isn't good enough in production unless you really do have a small app or a team of people who are extremely dedicated to fixing often sudden breaking changes that happen too often.

[@galaxies_dev]

Because I changed my opinion about things :)

Mmkv is Chinese made... So the encryption is probably broken 😂

[@user-kx9jf6ub1f]

If your intention is to help the others. Make them learn, then u should F***ING provide code link repo, or else there is no point. Thank you.

[@galaxies_dev]

Thanks for the feedback! I'll try to create a repo after the stream in the future. However, I don't think that simply copy and paste from a repository will help you to "learn" a topic.

[@Higurashi029]

no one responsible if you learn or not. if he does provide a code repo then thank him but if he doesn't still doesn't change the fact he's doing this for free...i don't believe on copy paste if your intention really to learn.

[@bugraotken]

If he (tutor) is creating the whole project with you, there is no point on sharing the code with you. If you want to add a repo to your portfolio like pretending you have completed the video with him, go and complete the video with him, otherwise sit and cry man.
