theme_provider

Easy to use, customizable and pluggable Theme Provider.

This is still a work in progress.

Include in your project

dependencies:
  theme_provider: ^0.0.1

run packages get and import it

import 'package:theme_provider/theme_provider.dart';

if you want the dialog:

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(
      themes: <AppTheme>[
        AppTheme(data: ThemeData.light()),
        AppTheme(data: ThemeData.dark()),
      ],
      builder: (context, theme) => MaterialApp(
        home: HomePage(),
        theme: theme,
      ),
    );
  }
}

To change the theme:

 ThemeCommand.of(context).nextTheme();

Access theme data using default method:

 Theme.of(context).data

TODO

• Add next theme command
• Add theme cycling widget
• Add theme selection by theme id
• Add theme select and preview widget
• Persist current selected theme
• Add unit tests and example

API Plan

This is what the API is supposed to look like after publishing

import 'package:flutter/material.dart';

class DataOptions{
	final Color textColorOnPrimaryColor;
	final Color textColorOnAccentColor;

	DataOptions({this.textColorOnPrimaryColor, this.textColorOnAccentColor});
}


class MyApp extends StatelessWidget{
	@override
	Widget build(BuildContext context){
		return ThemeProvider(
			loadFromDeviceIfPossible: true,
			saveThemeChangesToDevice: true,
			defaultThemeId: "dark_theme",
			themeSwitchErrorHandler: ThemeSwitchErrorHandler.SILENTLY_DEFAULT,
			themes: [
				DefaultTheme.pinkAppTheme(
					options: DataOptions(
							textColorOnPrimaryColor: Colors.black,
							textColorOnAccentColor: Colors.black,
						),
					),
				AppTheme(
					id: "dark_theme",
					description: "Dark theme - white combined with black",
					data: ThemeData(
							primaryColor: Colors.black,
							accentColor: Colors.white,
							brightness: Brightness.dark,
						),
					options: DataOptions(
							textColorOnPrimaryColor: Colors.white,
							textColorOnAccentColor: Colors.black,
						),
				),
				AppTheme(
					id: "light_theme",
					description: "Light theme - only white",
					data: ThemeData(

						),
				),
			],
			builder: (theme) => MaterialApp(
				theme: theme,
				home: HomePage(),
			),
		);
	}
}


class HomePage extends StatelessWidget{
	@override
	Widget build(BuildContext context){
		return Scaffold(
				appBar: AppBar(title: Text("Example"), actions: CycleThemeIconButton()),
				body: Builder(
					builder: (context) => Center(
						child: FlatButton(
							child: Text("Press ME",
									style: TextStyle(color: AppThemeOptions.of(context).textColorOnAccentColor)
								),
							onPressed(){
								ThemeController.of(context).nextTheme();
								ThemeController.of(context).prevTheme();

								if (Theme.of(context).brightness == Brightness.light){
									ThemeController.of(context).setTheme('dark_theme');
								}

								showDialog(context: context, ThemeSelectorDialog());
							}
						),
					),
				),
			);
	}
}
