for react native, the reason is as a result of the "react-native-gesture-handler" version is higher than the javascript version. You can reduce the version to lower version

"react-native-gesture-handler": "^1.10.3",

Please ensure that the following dependencies and their respective versions are accurately specified in your package.json file:

"react-native": "0.73.4",
"react-native-gesture-handler": "~2.14.0",
"react-native-reanimated": "3.6.2"

Update the dependencies in your project. this way,

for npm,

npm install @react-navigation/native@latest
npm install react-native-gesture-handler@latest
npm install react-native-reanimated@latest

for yarn,

yarn add @react-navigation/native@latest
yarn add react-native-gesture-handler@latest
yarn add react-native-reanimated@latest

For me was different version of this package installed on the project, so be aware in case you getting such error you probably will also get this warnings in logs:

Next solution is to check if you have this package installed. A good advice for me was to follow instructions presented in errors, 90% responses is there.

npx expo install react-native-gesture-handler

npx expo start --clear

I had the same issue. I had old codebase which I wanted to update with the latest versions. I was able to mitigate the issue following the below expo documentation. https://docs.expo.dev/tutorial/gestures/#install-and-configure-libraries

As previous answers suggest installing react-native-gesture-handler resolves the issue.

But in the codebase react-native-gesture-handler is not used anywhere, I don't get it, what is the purpose of installing the library that you don't use. Does it have something to do with expo?

I was able to install react-native-gesture-handler with

npx expo install react-native-gesture-handler

but I am still getting this error as well: ERROR TypeError: _RNGestureHandlerModule.default.flushOperations is not a function (it is undefined), js engine: hermes

I have been importing it like so

import { GestureHandlerRootView} from 'react-native-gesture-handler'

I am also only experiencing this issue on Android, but not on iOS

In Expo go everything is working amazing, but development build crashing : https://forums.expo.dev/t/in-expo-go-everything-is-working-amazing-but-development-build-crashing/74480
Troubleshooting : https://reactnavigation.org/docs/4.x/troubleshooting/
Problem with the version of react-native-gesture-handler that you have installed. The error message indicates that the flushOperations method is undefined, which suggests that the method is not being exposed properly by the library.
```
npx expo install react-native-gesture-handler 
```
