Getting Started

Installation

Add the package to your pubspec.yaml:

dependencies:
  littlefish_theming_m3:
    path: ../littlefish_theming_m3

Then run:

flutter pub get

Usage

Import the theming service:

import 'package:littlefish_theming_m3/littlefish_theming_m3.dart';

Initialize and use the theme manager in your app:

You can update the theme mode dynamically:
