spacing_generator 0.1.0

Code generation for spacings in Flutter. Automatically generate SizedBoxes and Paddings from defined sizes.

Spacing Generator

Installation

spacing_generator depends on these packages to work:

• build_runner
• spacing_generator_annotation

In your pubspec.yaml add the following dependencies:

dependencies:
  spacing_generator_annotations: ^0.0.2

dev_dependencies:
  spacing_generator: ^0.0.2
  build_runner: any

Usage

This package allows to simply generate spacings from a file like

import 'package:flutter/material.dart'; // don't forget to import material

@Spacing()
class SpaceValues {
  
  static const tiny = 2.0;
  static const small = 4.0;
  
}

Run the build_runner to generate code:

dart run build_runner build

It creates an extension that allows to use spacings and paddings like:

Widget build(BuildContext context) {
  return Padding(
      padding: context.paddings.allTiny,
      child: Column(
          children: [
            const Text('Hello'),
            context.spacings.horizontalSmall,
            const Text('World'),
          ]
      )
  );
}
