Inspired by Panache, a Flutter material theme editor for you to configure the overall visual theme of your material app.

Using the Generated Theme

Flutter Theme allows you to export your generated theme as a json file using json_theme. To use this theme in your app, follow the steps below:

  1. Add json_theme as a dependency in your pubspec.yaml file.
dependencies:
  json_theme: ^2.1.0+2

2. Copy the generated json file to your app project and place it under the assets/ folder.

3. Update your pubspec.yaml file to include your asset.

flutter:
  assets:
    - assets/flutter_theme.json

4. Update your main function to load your theme.

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  final themeStr = await rootBundle.loadString('assets/flutter_theme.json');
  final themeJson = jsonDecode(themeStr);
  final theme = ThemeDecoder.decodeThemeData(themeJson)!;
}

5. You can then pass in theme to your MaterialApp widget to use it.

MaterialApp(
  theme: theme,
  title: 'Flutter Theme',
  home: HomePage(),
);

For a complete example app using the generated json theme file, see the app under the example/ folder.
