Java – realm: change the name of the migrated field

I want to change the field name during the real DB migration

Is it correct? It takes a lot of time

The following code is my trial version, which changes the field value to summary by copying and deleting

RealmSchema schema = realm.getSchema();
schema.get("Invoice")
.transform(new RealmObjectSchema.Function() {
    @Override
    public void apply(DynamicRealmObject obj) {
        obj.set("summary",obj.getString("value"));
    }
})
.removeField("value");

Solution

Maybe what you need is a method: renamefield

Example:

RealmSchema schema = realm.getSchema();
schema.get("Invoice").renameField("value","summary");
