Neat is a collection of small opinionated utilities designed to helps writing short and clean Flutter code.

Summary #

BuildContext extensions #

Neat provides a set of BuildContext extensions designed to reduce the amount of boilerplate code needed to achieve basic tasks in Flutter.

Text helpers #

A collection of methods to create Text widgets with pre-filled corresponding style from the context's textTheme.

before

Text(
  "Clean code is simple and direct.",
  style: Theme.of(context).textTheme.titleMedium,
);

after

context.titleMedium("Clean code is simple and direct.");

Theses helpers give you access to every Text properties so you can use them like regular text widgets.

context.titleMedium(
  String text, {
  Key? key,
  TextStyle? style,
  StrutStyle? strutStyle,
  TextAlign? textAlign,
  TextDirection? textDirection,
  Locale? locale,
  bool? softWrap,
  TextOverflow? overflow,
  double? textScaleFactor,
  int? maxLines,
  String? semanticsLabel,
  TextWidthBasis? textWidthBasis,
  TextHeightBehavior? textHeightBehavior,
});

Neat provides a text helper method for each text theme style:

// Material 3
context.displayLarge('displayLarge');
context.displayMedium('displayMedium');
context.displaySmall('displaySmall');
context.headlineLarge('headlineLarge');
context.headlineMedium('headlineMedium');
context.headlineSmall('headlineSmall');
context.titleLarge('titleLarge');
context.titleMedium('titleMedium');
context.titleSmall('titleSmall');
context.bodyLarge('bodyLarge');
context.bodyMedium('bodyMedium');
context.bodySmall('bodySmall');
context.labelLarge('labelLarge');
context.labelMedium('labelMedium');
context.labelSmall('labelSmall');

// Material 2
context.headline1('headline1');
context.headline2('headline2');
context.headline3('headline3');
context.headline4('headline4');
context.headline5('headline5');
context.headline6('headline6');
context.subtitle1('subtitle1');
context.subtitle2('subtitle2');
context.bodyText1('bodyText1');
context.bodyText2('bodyText2');
context.caption('caption');
context.buttonText('button');
context.overline('overline');

Text's theme override #

Neat also provides a simple way to override the base text theme's TextStyle. Any TextStyle object passed through the style property of a text helper will be automatically merged with the corresponding text theme's base style using TextStyle.merge method.

before

Text(
  "Clean code reads like well-written prose.",
  style: Theme.of(context).textTheme.titleMedium?.copyWith(
    color: Colors.blue,
  ),
);

after

context.titleMedium(
  "Clean code reads like well-written prose.",
  style: TextStyle(color: Colors.blue),
);

Theme accessors #

A collection of helpers to facilitate the theme access.

before

Theme.of(context);
Theme.of(context).textTheme;
Theme.of(context).colorScheme;

after

context.theme;
context.textTheme;
context.colorScheme;

Generated widgets and helpers #

A collection of code generators designed to generate project-specific convenience widgets and helpers.

🚨 Make sure you have correctly installed neat_generator and build_runner as dev dependencies to use this part of the package.

🔧 This part of the package is optional. If you don't like it, just don't install neat_generator.

Setup the generator #

If you want to use the Neat's code generator, you will need neat_generator package and and a typical build_runner/code-generator setup. Run the following command to add neat_generator and build_runner packages to your dev dependencies:

flutter pub add neat_generator --dev
flutter pub add build_runner --dev

These commands will add the following dependencies to your pubspec.yaml file:

dependencies:
  neat:

dev_dependencies:
  neat_generator:
  build_runner:

To run neat's generator, use the following command. You can find more infos on build_runner's pub page.

flutter pub run build_runner build --delete-conflicting-outputs

Ignore lint warnings on generated files #

Depending on your lint options, Neat Generator may cause your linter to report warnings.

The solution to this problem is to tell the linter to ignore generated files, by modifying your analysis_options.yaml:

analyzer:
  exclude:
    - "**/*.nt.dart"

Dimensions class based generated widgets #

A good practice is to keep all constants inside a dedicated data class so all your widget can share same values:

class Dimensions {
  // Blank Spaces
  static const double spaceSmall = 8;
  static const double spaceMedium = 13;
  static const double spaceLarge = 21;

  // Paddings
  static const double paddingSmall = 3;
  static const double paddingMedium = 5;
  static const double paddingLarge = 8;
}

Then you can access theses values inside your widget tree:

SizedBox(
  width: Dimensions.spaceSmall
  height: Dimensions.spaceSmall
);
Container(
  padding: EdgeInsets.all(Dimensions.paddingSmall),
  child: ...
)

Neat provides a set of generators that can parse such data classes and generate useful widgets with pre-filled values. To use a generator, annotate your data class with @Neat.generate and run the flutter pub run build_runner build.

dimensions.dart

import 'package:neat/generator.dart';

part 'dimensions.nt.dart';

@Neat.generate
class Dimensions {
  static const double spaceSmall = 21;
  static const double spaceMedium = 34;
  static const double spaceLarge = 55;
}

Space widgets #

Generate a set of SizedBox with pre-filled width and height, based on the data class you've provided.

By default, the space widget generator will use generate a Space widget for each constant of the class starting with space. You can customize this behavior by using the @NeatGenerate() annotation. See generator options for advanced usage.

before

SizedBox(height: Dimensions.spaceSmall, width: Dimensions.spaceSmall);
SizedBox(height: 0, width: Dimensions.spaceMedium);
SizedBox(height: Dimensions.spaceLarge, width: 0);

after

const SpaceSmall();   
const SpaceMedium.w();
const SpaceLarge.h();

Padding helpers #

Generate a set of classes that inherit from EdgeInsets with pre-filled padding values, based on the data class you've provided.

By default, the space widget generator will use generate a Padding widget for each constant of the class starting with padding. You can customize this behavior by using the @NeatGenerate() annotation. See generator options for advanced usage.

before

EdgeInsets.all(Dimensions.paddingSmall),

EdgeInsets.symmetric(horizontal: Dimensions.paddingMedium),
EdgeInsets.symmetric(vertical: Dimensions.paddingMedium),

EdgeInsets.only(right: Dimensions.paddingLarge),

EdgeInsets.only(
  right: Dimensions.paddingLarge,
  left: Dimensions.paddingLarge,
  bottom: Dimensions.paddingLarge,
),

after

PaddingSmall(),

PaddingMedium.horizontal(),
PaddingMedium.vertical(),

PaddingLarge.right(),

// only available if generateBinaryFlagConstructor is true
PaddingLarge(right | left | bottom),
