Guide:

First run the initialization which is asynchronous so you will need to change the return type of your main() method from void to Future<void>:

Future<void> main() async {
  /// ensure widgets are initialized
  WidgetsFlutterBinding.ensureInitialized();

  /// initialize theme mode builder
  await ThemeModeBuilderConfig.ensureInitialized();

  /// Runs the app :)
  runApp(MyCoolApp());
}

Then just wrap your MaterialApp widget with the ThemeModeBuilder and return the MaterialApp widget from the builder. The builder gives you two arguments, builder: (BuildContext context, ThemeMode themeMode) {}. Pass the themeMode to themeMode on your MaterialApp.

Now this code below explains better than I do 🙈🚀😂:

import "package:flutter/material.dart";
import "package:theme_mode_builder/theme_mode_builder.dart";

class MyCoolApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ThemeModeBuilder(
      builder: (BuildContext context, ThemeMode themeMode) {
        return MaterialApp(
          title: "My Cool App",

          /// here is the `themeMode` passed form the `builder`
          themeMode: themeMode,
          theme: ThemeData(
            colorScheme: ColorScheme.fromSeed(
              brightness: Brightness.light,
              seedColor: Colors.red,
            ),

            /// put your light theme data here
          ),
          darkTheme: ThemeData(
            colorScheme: ColorScheme.fromSeed(
              brightness: Brightness.dark,
              seedColor: Colors.deepPurple,
            ),

            /// put your dark theme data here
          ),
          home: Home(),
        );
      },
    );
  }
}

If you want to change the themeMode you just call:

await ThemeModeBuilderConfig.toggleTheme();

And the theme will change instantly given you followed the steps above correctly 🎉.

Want more customization?

To change to dark mode:

await ThemeModeBuilderConfig.setDark();

To change to light mode:

await ThemeModeBuilderConfig.setLight();

To change to system mode:

await ThemeModeBuilderConfig.setSystem();

To get the theme mode you can run:

final ThemeMode themeMode = ThemeModeBuilderConfig.getThemeMode();

Finally, To check if the current theme is dark or not, you use this simple call:

final bool isDarkTheme = ThemeModeBuilderConfig.isDarkTheme();
