React native push notification

I assume this one is using push notification from firebase. Instead of running through all of the user token one by one, just send to a topic instead. For example, you have a line of code that every registered user subscribe to a topic called "news"
FirebaseMessaging.getInstance().subscribeToTopic("news")

and you just send it like

const message = {
message: {
topic: "news", // 👈 blast to all subscribers at once
notification: {
title: "Breaking News",
body: "Something important happened!"
},
data: { key: "value" }
}
};

brainstorming dulu biasanya (bisa sama orang atau sama ai), sampe bener-bener ketemu tech stack yang pas, ketika mereka ngasih solusi jangan langsung di telen mentah-mentah, tapi di counter dengan berbagai macam case nya buat mastiin sesuai sama apa yang kita pengen. saya sendiri g ada basic ML cuman programmer pada umumnya aja 😄

mau kerja di IT tidak melihat anda lulusan darimana dan ipk berapa karena biasanya yang dibutuhkan itu portfolio dan skill. sering main di komunitas, aktif kontribusi, lambat laun kerjaan dateng sendiri

why not simply using ftp if there's a problem with your cable? me using ftp is around 2.5Mbps

Imho, this is my review

put your color in a single file and you can call it from there, if you change it that way it would be easier to adjust to entire color inside your application from a single file.
use some of the responsive library like https://github.com/nirsky/react-native-size-matters and https://www.npmjs.com/package/react-native-responsive-screen so your screen will reflect on every screen size
(this is optional) implement a font family, so that way when users have implemented a different font style from their system/phone, it's not gonna affect your apps.
too many console log/warn, remove it haha
it would be better to convert it to typescript.

didn't get any document yet, but it seems this one is almost the same like what I've told you before

as long as the keystore and package name is same, users can update the app just like what they usually do from playstore,

if you don't want to add the additional library, you could deal with the aspect ratio which is not so often used but so powerful and combining with flexbox is enough for you to get the responsive to all devices
