If you are facing an issue where the FlatList component is not scrolling inside a BottomSheetModal in React Native, you are not alone. This can be a common problem, but fortunately, there are multiple solutions to resolve it. Let’s explore them below:

Solution 1: Use react-native-gesture-handler

The first solution is to use the react-native-gesture-handler library. This library provides a more performant touch handling system for React Native applications.
First, install the library by running the following command:

npm install react-native-gesture-handler

Next, you need to link the library to your project. Run the following command:

react-native link react-native-gesture-handler

After linking the library, you need to configure it. Open your project’s main file, usually named index.js or App.js, and add the following code:

import 'react-native-gesture-handler';

Finally, import the gestureHandlerRootHOC function from the library and wrap your app’s root component with it. This will enable the gesture handling system:

import { gestureHandlerRootHOC } from 'react-native-gesture-handler';

const App = () => {
  // Your app's code here
};

export default gestureHandlerRootHOC(App);

Solution 2: Set the height of the BottomSheetModal

If Solution 1 didn’t work for you, another approach is to explicitly set the height of the BottomSheetModal component. Sometimes, the FlatList may not scroll if the BottomSheetModal’s height is not properly defined.
Here’s an example of how you can set the height of the BottomSheetModal:

import { BottomSheetModal } from 'react-native-bottom-sheet';

const MyComponent = () => {
  return (
    
      
    
  );
};

Solution 3: Use a ScrollView instead of FlatList

If neither of the above solutions work for you, you can try using a ScrollView instead of a FlatList. The ScrollView component is a generic scrolling container that can be used to render a list of items.
Here’s an example of how you can replace the FlatList with a ScrollView:

import { ScrollView } from 'react-native';

const MyComponent = () => {
  return (
    
      
        {/* Render your items here */}
      
    
  );
};

With these solutions, you should be able to resolve the issue of the FlatList not scrolling inside a BottomSheetModal in React Native. Try them out and see which one works best for your specific use case.

Happy coding!
