Overview
The contextualactionbar package provides a workaround for implementing a Contextual Action Bar (CAB) in Flutter, enabling a dynamic top app bar that replaces the standard app bar to display context-specific actions when items are selected. Designed for use across multiple platforms including Android, iOS, Web, macOS, Windows, and Linux, it enhances user interaction by offering targeted controls during selection modes. The package integrates seamlessly with existing Flutter apps and supports custom styling and behavior. It is particularly useful in list or grid interfaces where users need to perform batch operations.
