flutter_lists 0.0.2

A user-friendly Flutter package designed to make the process of creating unordered lists in Flutter applications easy and straightforward.

Introduction

The "flutter_lists" package offers a "UnorderedList" widget that simplifies the creation of unordered lists in Flutter applications. The widget allows developers to define a list of items and customize various aspects of the list, such as the bullet icon, bullet color, physics, and item builders.

Features

1. Customization: Users can customize the appearance of the list by specifying the bullet icon and its color. Additionally, they can set the scroll physics to control the list's scrolling behavior.

2. Flexible Item Builders: Developers have the option to provide a custom item builder or a title builder for the list. The item builder allows users to create custom list items, while the title builder is used to determine the title string from each item.

3. Default Bullet Icon: If no bullet icon is provided, the widget uses a default bullet icon from the predefined list of icons.

4. Item Tap Functionality: The widget supports an onTap function that allows users to define actions when a list item is tapped. The onTap function can be provided globally for the entire list or individually for each item, depending on whether an item builder is used.

5. Error Handling: The package handles common errors effectively, such as checking if both the item builder and title builder properties are set simultaneously, and ensuring that a title builder is provided when the item type is not a String.

Getting started

Step 1: Add the Package to pubspec.yaml To begin, open your project's pubspec.yaml file and add the flutter_lists package as a dependency:

dependencies:
  flutter:
    sdk: flutter
  flutter_lists: ^1.0.0

Step 2: Install the Dependencies After adding the dependency to your pubspec.yaml, save the file, and run the following command in your terminal to fetch and install the package:

flutter pub get

Step 3: Import the flutter_lists Package In the Dart file where you want to use the unordered lists, import the flutter_lists package:

import 'package:flutter/material.dart';
import 'package:flutter_lists/flutter_lists.dart';

Usage

Basic Unordered List of Strings

List<String> groceries = ['Apples', 'Bananas', 'Milk', 'Bread'];

UnorderedList<String>(
  items: groceries,
);

Custom Bullet Icon and Color

List<String> tasks = ['Read a book', 'Exercise', 'Cook a meal'];

UnorderedList<String>(
  items: tasks,
  bulletIcon: Icons.check_circle, // Custom bullet icon
  iconColor: Colors.green, // Custom bullet icon color
);

#Handling Item Taps

List<String> countries = ['USA', 'Canada', 'India', 'Australia'];

UnorderedList<String>(
  items: countries,
  onTap: (item) {
    print('Selected country: $item');
    // Implement your logic here when an item is tapped
  },
);

Providing a Title Builder

List<String> fruits = ['Apple', 'Banana', 'Orange'];

UnorderedList<String>(
  items: fruits,
  titleBuilder: (fruit) => 'Fruit: $fruit',
);

Custom Item Builder

List<int> numbers = [1, 2, 3, 4, 5];

UnorderedList<int>(
  items: numbers,
  itemBuilder: (number) {
    return ListTile(
      title: Text('Number: $number'),
    );
  },
);

Usage with User defined datatypes

class Task {
  String title;
  String description;
  bool isCompleted;

  Task({
    required this.title,
    required this.description,
    this.isCompleted = false,
  });
}

List<Task> tasks = [
  Task(
    title: 'Buy groceries',
    description: 'Milk, Eggs, Bread',
  ),
  Task(
    title: 'Read a book',
    description: 'Science fiction novel',
    isCompleted: true,
  ),
  Task(
    title: 'Complete Flutter project',
    description: 'Add finishing touches',
  ),
];

UnorderedList<Task>(
  items: tasks,
  itemBuilder: (task) {
    return ListTile(
      title: Text(task.title),
      subtitle: Text(task.description),
      leading: task.isCompleted
          ? Icon(Icons.check_circle, color: Colors.green)
          : Icon(Icons.circle, color: Colors.grey),
      onTap: () {
        // Perform actions when a task is tapped
        print('Tapped task: ${task.title}');
      },
    );
  },
);
