Widgets Spacing Library

The widgets_spacing library provides utility functions and extensions for adding consistent spacing between widgets in a Flutter application. This library uses the gap package to insert gaps between widgets.

Features

• Custom Spacing: Easily define spacing between widgets with a configurable multiplier.
• List Extension: Add spacing to a list of widgets using an extension method.
• Flexible Spacing: Specify different sizes for gaps between widgets.

Usage

Import the Library

import 'package:widgets_spacing/widgets_spacing.dart';

Basic Usage

The spacing function returns the default spacing (8.0) multiplied by the given size.

final double defaultSpacing = spacing(); // 4.0
final double doubleSpacing = spacing(2); // 8.0

Constant values

kSmallSpacing: 8.0
kMediumSpacing: 16.0
kLargeSpacing: 32.0

Adding Spacing Between Widgets

Use the widgetsSpacing function to add gaps between widgets.

final widgets = [
  Text('First'),
  Text('Second'),
  Text('Third'),
];

final spacedWidgets = widgetsSpacing(widgets, size: 2);

// Use the spacedWidgets in your widget tree
Column(
  children: spacedWidgets,
);

Extension Method

Use the withSpace extension method on a list of widgets to add gaps.

final widgets = [
  Text('First'),
  Text('Second'),
  Text('Third'),
];

final spacedWidgets = widgets.withSpace(2);

// Use the spacedWidgets in your widget tree
Column(
  children: spacedWidgets,
);

Row(
  children: spacedWidgets,
);

Number extensions, use .toSpacing

2.toSpacing: 8.0
4.toSpacing: 16.0
8.toSpacing: 32.0

Example

Here's a complete example demonstrating how to use the widgets_spacing library:

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

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Widgets Spacing Example')),
        body: Padding(
          padding: EdgeInsets.all(spacing(4)),
          child: Column(
            children: [
              Text('First'),
              Text('Second'),
              Text('Third')
            ].withSpace(2),
          ),
        ),
      ),
    );
  }
}
