easy_dynamic_theme 0.0.1

A new flutter plugin project.

Easy Dynamic Theme

This is a new and easy approach on Flutter Themes.

Automatically you will get your OS defined Theme (Dynamic) or just force one of your preference (Light / Dark) and of course, persist this choice in your device.

Easy peasy, don't you think? ;)

Getting Started

For help getting started with Flutter, view our
online documentation, which offers tutorials,
samples, guidance on mobile development, and a full API reference.

Minimum Requirements

• Dart SDK: >=2.7.0 <3.0.0
• Flutter: >= 1.17.0

Installation and Usage

Once you're familiar with Flutter you may install this package adding easy_dynamic_theme to the dependencies list
of the pubspec.yaml file as follow:

dependencies:  
 flutter: sdk: flutter  
 easy_dynamic_theme: ^0.0.1

Then run the command flutter packages get on the console.

Examples of use

All magic occurs in your main.dart file

The following code shows code commented as optional with which you can avoid "flickering" when switching from light to dark mode when the application loads.

void main() async { 
  WidgetsFlutterBinding.ensureInitialized();  

  ThemeMode initialThemeMode;
  
  // [OPTIONAL - BEGIN]
  SharedPreferences sp = await SharedPreferences.getInstance();
  bool isDark = sp.getBool('is_dark'); 
  if (isDark != null) { 
    initialThemeMode = isDark ? ThemeMode.dark : ThemeMode.light;
  }
  // [OPTIONAL - END]
  
  runApp( 
    EasyDynamicThemeWidget( 
      initialThemeMode: initialThemeMode, 
      child: MyApp(), 
    ), 
  );
}  
  
class MyApp extends StatelessWidget {  
  final String title = 'Dynamic Theme'; 
   
  @override 
  Widget build(BuildContext context) { 
    return MaterialApp( 
      title: title, 
      theme: lightThemeData, 
      darkTheme: darkThemeData, 
      themeMode: EasyDynamicThemeWidget.of(context).themeMode, 
      home: new MyHomePage(title: title,) 
    ); 
  }
}  

How to toggle from dynamic/light/dark in your app

  EasyDynamicTheme.of(context).switchTheme();

How to get your app current theme

ThemeMode themeMode = EasyDynamicTheme.of(context).themeMode;  

The above example will return a value of the enum used by MaterialApp ThemeMode with one of the following values:

ThemeMode values:

Use either the light or dark theme based on what the user has selected in the system settings.

system

Always use the light mode regardless of system preference.

light

Always use the dark mode (if available) regardless of system preference.

dark

What about some widgets?

Right now we have the EasyDynamicThemeBtn widget, which is a flat icon that displays the icon according to the current theme of your app and allows you to switch between them.
