Erase all data from Expo React Native App

Yes, you can programmatically delete data from your React Native app using Expo by utilizing the AsyncStorage API. However, it’s important to note that the AsyncStorage API is asynchronous, so you need to handle the promises appropriately.

To delete all the data stored in AsyncStorage, you can use the multiRemove method. Try to use that:

import AsyncStorage from '@react-native-async-storage/async-storage';

// Function to delete all data from AsyncStorage
const deleteAllData = async () => {
  try {
    const allKeys = await AsyncStorage.getAllKeys(); // Get all keys from AsyncStorage
    await AsyncStorage.multiRemove(allKeys); // Remove all keys

    // Display a success message or perform any other actions
    console.log('All data deleted successfully!');
  } catch (error) {
    // Handle error
    console.log('Error deleting data:', error);
  }
};

// Usage example
deleteAllData();

Remember to install the @react-native-async-storage/async-storage package in your project.

expo install @react-native-async-storage/async-storage

When you remove an item from AsyncStorage using the removeItem method, it should delete the specific key-value pair from storage, and the value associated with that key should no longer be accessible.

If you are observing that the amount of storage allocated to your application remains the same after removing items from AsyncStorage, it could be due to a few reasons:

• Data is stored elsewhere: AsyncStorage may be using a different storage mechanism or location on the device than what is visible in the application’s allocated storage.

• Caching or temporary storage: It’s possible that the storage you’re seeing allocated to the application is being used for caching or temporary storage purposes by the operating system or other components of your app.

• Other data sources: Your application may be using additional data sources or storage mechanisms apart from AsyncStorage.
