auto_input_box 0.0.2

A Flutter package for dynamic input boxes with auto-suggestions and overlay-based UI components.

AutoInputBox Plugin

The AutoInputBox Plugin is a Flutter widget that provides an enhanced text input experience with auto-completion functionality. It dynamically filters suggestions as users type and displays them in a dropdown list, making it ideal for search fields, forms, or any text input where suggestions improve the user experience.

Features

• Debounced Input Filtering: Ensures efficient suggestion filtering with customizable debounce time.

• Dynamic Dropdown: Displays suggestions in an overlay that updates in real time.

• Customizable: Fully customizable styles, input decorations, and callback options.

• Type-Safe: Supports any object type with a display string conversion function.

Add the following dependency to your pubspec.yaml file:
