FlorisBoard

FlorisBoard is a beta keyboard for Android 7.0 and later, with themes, clipboard and emoji interfaces. For a reusable appearance, its extension guide describes creating a theme extension, basing a stylesheet on an existing theme, editing it in the app and packaging it for reuse. That guide applies from v0.4.0-beta03 and limits dynamically created extensions to themes; language and keyboard extensions are described as partially functional and built-in only. The permissions guide lists vibration and notifications as optional functions, so those permissions are distinct from the basic typing workflow.
