There are often discrepancies between the functionality offered by a platform and the desired behavior in the end-user experience. The platform surfaces capabilities from the underlying device as building blocks towards larger features. On the other hand, developers require higher level affordances built on-top of these features, such as persistence and update publishing. In isolation, implementing such functionality reinvents the wheel and increases maintenance. When multiple parties are involved, coordination across experiences quickly becomes an involved effort.

Settings bridges this divide by interacting with the platform in a manner amenable to end-user experiences. Part of the Fuchsia SDK, it provides a uniform model for accessing and controlling various aspects of the platform. Supported features benefit from additional functionality commonly needed by applications. As the source of truth, Settings ensures consistency across its consumers. Finally, Settings is built for configurability; The manifest and behavior of features can be tailored to the product’s need at both build and runtime.
