currently try

 import { polyfillGlobal } from "react-native/Libraries/Utilities/PolyfillFunctions"

const applyGlobalPolyfills = () => {
  const { TextEncoder, TextDecoder } = require("text-encoding")

  polyfillGlobal("TextEncoder", () => TextEncoder)
  polyfillGlobal("TextDecoder", () => TextDecoder)
}

export default applyGlobalPolyfills

 import { polyfillGlobal } from "react-native/Libraries/Utilities/PolyfillFunctions"

const applyGlobalPolyfills = () => {
  const { TextEncoder, TextDecoder } = require("text-encoding")

  polyfillGlobal("TextEncoder", () => TextEncoder)
  polyfillGlobal("TextDecoder", () => TextDecoder)
}

export default applyGlobalPolyfills

in my_layout.tsx

// calling this 
applyGlobalPolyfills()

// calling this 
applyGlobalPolyfills()
