Dosty Theme Management

---

Dosty Theme Management is a powerful Flutter package designed to simplify theme management within your applications. It provides an intuitive way to define and switch between light and dark modes while allowing you to add your own custom colors.

Features

• Easy Theme Management: Effortlessly manage themes for your Flutter application.
• Custom Color Support: Add your own colors with defined light and dark variations.
• Theme Mode Toggling: Easily toggle between different theme modes, including System, Light, and Dark.
• Streamlined Integration: Quickly integrate with your existing Flutter projects.

Installation

To install the Dosty Theme package, use the following command in your terminal:

run flutter pub add dosty_theme

then run flutter pub add dosty_theme_annotation

and run dart pub add dosty_theme_generator

Usage

1. Create a Theme Class
   Define a class for your theme that extends from the generated class. The class name should match the desired theme name.

import 'file_name.g.dart';

@DostyTheme
class MyTheme extends _$MyTheme {
}

after run dart run build_runner build or dart run build_runner watch

2. Define Your Colors Create a list of colors using the DostyColor class, specifying the light and dark variants.

List<DostyColor> data = [
  DostyColor(name: 'color1', light: Colors.white, dark: Colors.black),
  DostyColor(name: 'color2', light: Colors.black, dark: Colors.white),
  DostyColor(name: 'color3', light: Colors.amber, dark: Colors.red),
  DostyColor(name: 'color4', light: Colors.amber, dark: Colors.red),
  DostyColor(name: 'grey2', light: Colors.grey, dark: Colors.blueGrey),
  DostyColor(name: 'grey3', light: Colors.grey, dark: Colors.blueGrey),
];

3. Annotate Your Theme Class Use the @DostyTheme annotation to define the variables for your theme.

@DostyTheme(vars: [
  'color1',
  'color2',
  'color3',
  'color4',
  'grey2',
  'grey3',
])
class MyTheme extends _$MyTheme {
  MyTheme() : super(myColors: data, mode: ThemeMode.dark);
}

Full code

// ignore_for_file: unused_field, prefer_typing_uninitialized_variables, prefer_final_fields

import 'package:dosty_theme/dosty_theme.dart';
import 'package:dosty_theme_annotation/dosty_theme_annotation.dart';
import 'package:flutter/material.dart';
part 'my_theme.g.dart';

List<DostyColor> data = [
  DostyColor(name: 'color1', light: Colors.white, dark: Colors.black),
  DostyColor(name: 'color2', light: Colors.black, dark: Colors.white),
  DostyColor(name: 'color3', light: Colors.amber, dark: Colors.red),
  DostyColor(name: 'color4', light: Colors.amber, dark: Colors.red),
  DostyColor(name: 'grey2', light: Colors.grey, dark: Colors.blueGrey),
  DostyColor(name: 'grey3', light: Colors.grey, dark: Colors.blueGrey),
];

@DostyTheme(vars: [
  'color1',
  'color2',
  'color3',
  'color4',
  'grey2',
  'grey3',
])
class MyTheme extends _$MyTheme {
  MyTheme() : super(myColors: data, mode: ThemeMode.dark);
}

4. Create an object in main file

MyTheme myTheme = MyTheme();
void main() {
  runApp(const MyApp());
}

5. Wrap your child of MyApp with DostyTheme you can use myTheme.DostyTheme():

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

  @override
  Widget build(BuildContext context) {
    return myTheme.DostyTheme(
      context: context,
      materialApp: MaterialApp(
        title: 'Flutter Demo',
        theme: ThemeData(
          colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
          useMaterial3: true,
        ),
        home: const MyHomePage(title: 'Flutter Demo Home Page'),
      ),
    );
  }
}

6. Using Your Theme Colors You can now use your defined colors throughout your app:

Container(
  width: 100,
  height: 100,
  decoration: BoxDecoration(color: myTheme.color3),
  child: Text('Example'),
);

For a shorter method of accessing some colors within ThemeData:

Container(
  width: 100,
  height: 100,
  decoration: BoxDecoration(color: myTheme.primary(context)),
  child: Text('Example'),
);

7. Toggle Theme You can easily toggle the theme mode using a switch:

Switch(
  value: myTheme.isDark,
  onChanged: (value) {
    myTheme.toggle();
  },
);
