Frigade has introduced a new feature that allows users to dynamically inject content from their applications directly into their flows, enabling the setting of variables dynamically within the flows. This capability is particularly useful for personalizing content, such as setting a user's name or loading localized strings. Users can now define custom variables anywhere in the data specified through the Frigade dashboard, which can be implemented in React by setting a map of custom variables either directly on the flow. This enhancement is demonstrated with an example where a title in a flow-data.yml file is dynamically set to greet a user by their first name.
