Theme Kit

Create themes you'll enjoy using 🎨.

Features

• ✅ Easy to set dark and light themes.
• ✅ Use your own custom theme tokens on top of Material Design.
• ✅ Easy to use, just import the theme and use it in your Material components + autocompletion available for every theme token + custom documentation file automatically generated for your theme.
• ✅ Fully customizable, the generated code is editable and yours!
• ✅ Includes definition of colors, text styles, font families and font weights.
• ✅ Reusable. The theme is generated in a separate package that can be shared across multiple projects.
• ✅ No dependencies required.
• ✅ No build runner needed 😉.

Getting Started 🚀

To use theme kit follow these steps:

1. Install mason: https://docs.brickhub.dev/installing

2. Install the theme_kit brick

mason add theme_kit

3. Generate your theme in the desired directory (p.e. /packages) It is recomended to create a packages folder in the root of your Flutter project, create a package with the name of the theme (e.g. packages/my_theme) by running inside the packages folder the following command with the name of the theme (e.g. my_theme):

flutter create --template=package my_theme

4. Then, inside the package folder (e.g. /packages), run mason make theme_kit to replace and generate the necessary files for the theme.

mason make theme_kit

5. Follow the instructions to complete the installation. Make sure the name of the theme is the same as the package name. For example, in this case we use my theme as the theme name and mt as the prefix.

What is the name of the theme? (theme kit) my theme
What is the prefix you want to use in your theme classes? use lowercase, no spaces. Recommended to be 2-3 characters long. (tk) mt

After creating the theme package, go to the pubspec.yaml of the app (root project) and import it in the dependencies section. For example if the theme package name is my_theme it should look like this:

dependencies:
  my_theme:
    path: packages/my_theme

6. To use the fonts defined in the theme, you can define the fonts you want to use in the pubspec.yaml file of your app (root project). Here's an example of how you can define the fonts:

fonts:
  - family: Poppins
    fonts:
      - asset: packages/my_theme/fonts/Poppins-Regular.ttf
        weight: 400
      - asset: packages/my_theme/fonts/Poppins-Medium.ttf
        weight: 500
      - asset: packages/my_theme/fonts/Poppins-SemiBold.ttf
        weight: 600
      - asset: packages/my_theme/fonts/Poppins-Bold.ttf
        weight: 700

7. Now, you can use the theme like this (this example uses my theme as the theme name and mt as the prefix):

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


void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  static final _lightTheme = MtTheme(
    primary: Colors.blue,
    secondary: Colors.blueGrey[200],
    success: Colors.green,
    warning: Colors.yellow,
    error: Colors.red,
    info: Colors.blue,
    background: Colors.white,
    surface100: Colors.white,
    surface200: Colors.grey[100],
    textPrimary: Colors.black,
    textSecondary: Colors.grey,
    divider: Colors.grey[300],
    border: Colors.grey[300],
  );

  static final _darkTheme = MtTheme(
    primary: Colors.blue,
    secondary: Colors.blueGrey[700],
    success: Colors.green,
    warning: Colors.yellow,
    error: Colors.red,
    info: Colors.blue,
    background: Colors.black,
    surface100: Colors.grey[900],
    surface200: Colors.grey[800],
    textPrimary: Colors.white,
    textSecondary: Colors.grey,
    divider: Colors.grey[700],
    border: Colors.grey[700],
  );

  @override
  Widget build(BuildContext context) {
    return MyTheme(
      lightTheme: _lightTheme,
      darkTheme: _darkTheme,
      child: MaterialApp(
        title: 'Example',
        theme: ThemeData(primarySwatch: Colors.blue),
        home: const Home(),
      ),
    );
  }
}

class Home extends StatelessWidget {
  const Home({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: MtColor.background,
      body: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          const ThemeSettings(),
          MtText.displayXL("Display XL").styles(
            color: MtColor.secondary,
            fontWeight: MtFontWeight.bold,
          ),
          MtText.displayL("Display L").styles(
            color: MtColor.error,
            fontFamily: MtFontFamily.inter,
          ),
        ],
      ),
    );
  }
}

class ThemeSettings extends StatelessWidget {
  const ThemeSettings({super.key});

  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        MtText.displayXL("Theme Settings").styles(
          color: MtColor.textPrimary,
        ),
        Row(
          children: [
            ElevatedButton(
              child: MtText.bodyM("Light Theme"),
              onPressed: () {
                MyTheme.setLightTheme();
              },
            ),
            ElevatedButton(
              child: MtText.bodyM("Dark Theme"),
              onPressed: () {
                MyTheme.setDarkTheme();
              },
            ),
          ],
        ),
      ],
    );
  }
}
