dynamic_theme #

Dynamically changing your theme without hassle #

This packages manages changing your theme during runtime and persiting that theme.

I wrote a medium post about this, check it out here! #

Include in your project #

  dynamic_theme: ^1.0.0

run packages get and import it

import 'package:dynamic_theme/dynamic_theme.dart';

if you want the dialog:

import 'package:dynamic_theme/theme_switcher_widgets.dart';

Usage #

Wrap your material app like this:

class MyApp extends StatelessWidget {
  Widget build(BuildContext context) {
    return new DynamicTheme(
      defaultBrightness: Brightness.light,
      data: (brightness) => new ThemeData(
        primarySwatch: Colors.indigo,
        brightness: brightness,
      themedWidgetBuilder: (context, theme) {
        return new MaterialApp(
          title: 'Flutter Demo',
          theme: theme,
          home: new MyHomePage(title: 'Flutter Demo Home Page'),

Change the theme like this:

  void changeBrightness() {
    DynamicTheme.of(context).setBrightness(Theme.of(context).brightness == Brightness.dark? Brightness.light: Brightness.dark);
  void changeColor() {
    DynamicTheme.of(context).setThemeData(new ThemeData(
        primaryColor: Theme.of(context).primaryColor == Colors.indigo? Colors.red: Colors.indigo

When changing the brightness with setBrightness, it is additionally stored in the shared preferences.
