i have the same problem did you manage to fix it ? or find a solution ?

[ramyjaber1]

i solve this
npm i buffer
then add this at the top of you file under all the imports
window.Buffer = window.Buffer || require("buffer").Buffer;

@Ayomikuolatunji you can add the line in the root of your project. Eg. App.js, just after the imports.

./App.js

// your app imports here
window.Buffer = window.Buffer || require("buffer").Buffer;

const App = () => {
    return (
        ....your app code etc

Or if you use TypeScript:

./App.tsx

// your app imports here
// @ts-ignore
window.Buffer = window.Buffer || require("buffer").Buffer;

const App = () => {
    return (
        ....your app code etc
