API documentation

• Documentation for the latest stable release

Installation in managed Expo projects

For managed Expo projects, please follow the installation instructions in the API documentation for the latest stable release. If you follow the link and there is no documentation available then this library is not yet usable within managed projects — it is likely to be included in an upcoming Expo SDK release.

Installation in bare React Native projects

For bare React Native projects, you must ensure that you have installed and configured the expo package before continuing.

Add the package to your npm dependencies

yarn add expo-drag-drop-content-view

Configure for iOS

Run npx pod-install after installing the npm package.

Web blob URI cleanup

On web, dropped file assets carry a blob URI (asset.uri) created with URL.createObjectURL. Blob URIs hold memory until explicitly revoked — the recommended way to handle this is the useDropAssets hook, which revokes all URIs automatically on unmount and exposes a clear() method for manual flushing:

import { DragDropContentView, useDropAssets } from "expo-drag-drop-content-view";

export function DropZone() {
  const { assets, onDrop, clear } = useDropAssets();

  return (
    <>
      <DragDropContentView onDrop={onDrop} />
      <button onClick={clear}>Clear</button>
    </>
  );
}

If you manage assets yourself, call asset.release?.() when you're done with each one:

onDrop({ assets }) {
  // use assets ...
  assets.forEach((a) => a.release?.());
}
