I am using react native and expo 4.4.4 and
"react-native-material-dropdown": "^0.11.1",
This library was picked from this Npm link and Github Link
Just copy pasted the example usage code you have given...
Its showing below error :
TypeError: undefined is not an object (evaluating '_reactNative.Animated.Text.propTypes.style')

I don't think react-native-material-dropdown is supported in Expo.
Use #react-native-community/picker instead.

i have upgraded my project to ExpoSDK 46. On the web everything works well, but when trying to run the project on iOS or Android using the ExpoGo App, i’m getting the following error:

When I try to run the app, it crashes with the error below? I tried several methods for clearing the cashes, including uninstalling the resent package I installed on the app, but I couldn't figure out what was causing the error or how to fix it.

I want to generate seed phrase in react native using react-native-bip39.
But I have some problems using this module.
//
import bip39 from 'react-native-bip39'
const seed = async () => {
const seeds = await bip39.generateMnemonic(256)
console.log(seed)
}
//
After compile this I can see these errors below

I tried to generate seed phrase but it doesn't work actually
problem to connect the application to the backend.
I use React Native with EXPO
The error occurs on a login screen when trying to validate a user on a DB in the sql-server
I believe the error is in this: async function sendForm () {
let response = await fetch ('http://myip:3000/login'
however, I don't know what could be wrong ... suddenly some Node module is missing.
1 - already redone the project
2 - deleted node_modules and yarn install to remake
3 - already test the Controller.js routes and they are working.
4 - images: https://ibb.co/B354qky https://ibb.co/ZRjKRnn https://ibb.co/pyDyM70
