Selectify is a versatile Flutter library that simplifies the creation of selection components, supporting both single and multiple selections similar to radio buttons and checkboxes. Designed for high customizability, it provides a range of layout options, like grid, list, and wrap views, along with extensive styling and behavior configurations. This makes it ideal for crafting responsive, visually consistent, and intuitive selection UIs across various app themes and user scenarios.

Features

-	Single and Multiple Selection Support: Offers flexible configurations for single or multiple selection modes.
-	Highly Customizable: Control the layout, style, and interaction of each selection item.
-	Multiple Layouts: Display items in grid or wrap formats with cross-axis count and direction options.
-	Customizable Selection Model: Use the provided SelectionModel class or define your own for tailored control.
-	Works with Custom Widgets: Extend functionality using custom item builders to create unique selection experiences.

Getting Started

To get started, add selectify to your project by including it in your pubspec.yaml file:

dependencies:
  selectify: ^1.0.1

Then, import the library:

import 'package:selectify/selectify.dart';

Usage

Single Selection Example

Wrap Layout

Display items in a wrap layout that adjusts based on available screen width.

SingleSelection<String>.wrap(
    initialValue: items.last,
    items: items,
    onChanged: (item) {},
),

Grid Layout

Organize items in a grid with a defined number of items per row.

SingleSelection<String>.grid(
    crossAxisCount: 2, // Number of items per row
    initialValue: items.last,
    items: items,
    onChanged: (item) {},
),

Multiple Selection Example

MultipleSelection<String>.wrap(
    initialValue: items.last,
    items: items,
    onChanged: (item) {},
    // Enable multiple selection in a single row layout.
    direction: Axis.horizontal,
),

Customization

Grid Layout with custom SelectionModel

MultipleSelection<SelectionModel<String>>.grid(
    ...
    // Signature for a function that creates a widget for a given index,
    itemBuilder: (context, item, index, selected) {
        return Opacity(
            opacity: item.enable ? 1.0 : 0.5,
            child: Container(
                padding: EdgeInsets.all(8),
                decoration: BoxDecoration(
                border: Border.all(
                  color: selected ? Colors.blueAccent : Colors.black54,
                ),
                borderRadius: BorderRadius.circular(10),
            ),
            child: Row(
                mainAxisSize: MainAxisSize.min,
                children: [
                    Icon(
                      selected ? Icons.check_box : Icons.check_box_outline_blank_outlined,
                      color: selected ? Colors.blueAccent : Colors.black54,
                    ),
                    SizedBox(width: 8),
                    Expanded(
                      child: Text(item.valueShow ?? item.code),
                    ),
                  ],
                ),
            ),
        );
    },
),
