Alerter - An Android Alerter Library, now in Kotlin!
This library aims to overcome the limitations of Toasts and Snackbars, while reducing the complexity of your layouts.
General
With simplicity in mind, the Alerter employs the builder pattern to facilitate easy integration into any app. A customisable Alert view is dynamically added to the Decor View of the Window, overlaying all content.
