Topic preferences

The Batch Flutter Plugin allows you to:

• Add or remove topic preferences from a user profile (the profile is created automatically if it doesn’t already exist).

• Partially update topic preferences within a user profile.

Requires Batch-Flutter-Plugin 3.1+

Here’s how to update topic preferences:

BatchProfile.instance.newEditor()
  .setTopicPreferences([("technology", "finance"]) // Null to erase.
  // Alternatively, partially update them with:
  .addToTopicPreferences(["investing"])
  .removeFromTopicPreferences(["travel"])
  .save();

Note: Topics must be a valid List of String not longer than 25 items. String should be made of letters, numbers or underscores ([a-z0-9_]) and can't be longer than 300 characters.
