Include in your project

dependencies:
  theme_provider: ^0.0.1

run packages get and import it

import 'package:theme_provider/theme_provider.dart';

Usage

Wrap your material app like this:

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ThemeProvider(
      builder: (context, theme) => MaterialApp(
        home: HomePage(),
        theme: theme,
      ),
    );
  }
}

To change the theme:

 ThemeProvider.controllerOf(context).nextTheme();

Access current AppTheme

 ThemeProvider.themeOf(context)

Access theme data:

 ThemeProvider.themeOf(context).data
 // or
 Theme.of(context)

Passing Additional Options

This can also be used to pass additional data associated with the theme. Use options to pass additional data that should be associated with the theme.
eg: If font color on a specific button changes create a class to encapsulate the value.

  class ThemeOptions{
    final Color specificButtonColor;
    ThemeOptions(this.specificButtonColor);
  }

Then provide the options with the theme.

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
  return ThemeProvider(
    themes: themes: [
        AppTheme<ThemeOptions>(
            data: ThemeData.light(),
            options: ThemeOptions(Colors.blue),
        ),
        AppTheme<ThemeOptions>(
            data: ThemeData.dark(),
            options: ThemeOptions(Colors.red),
        ),
      ],
      builder: (context, theme) => MaterialApp(
        home: HomePage(),
        theme: theme,
      ),
  );
}
}

Then the option can be retrieved as,

ThemeProvider.optionsOf<ThemeOptions>(context).specificButtonColor
