How do I update data in Realm using React Native?

To update data in Realm, you first need to fetch the object you want to update, then modify its properties and save the changes.

Can you show me a code example for that?

Sure! Here's a simple example:

const realm = await Realm.open({ schema: [YourSchema] });
const item = realm.objectForPrimaryKey('YourSchema', itemId);

realm.write(() => {
  item.propertyName = 'newValue';
});

What if I want to update multiple properties?

You can update multiple properties within the same realm.write block like this:

realm.write(() => {
  item.property1 = 'newValue1';
  item.property2 = 'newValue2';
});

Is there a way to handle errors during the update?

Yes, you can use a try-catch block around your write operation to handle any errors that may occur.
