In today’s digital world, user interface (UI) design plays a crucial role in application usability. If you wish to create a Flutter app with a stylish light-dark toggle feature, you’re in the right place! In this guide, we’ll walk you through the simple yet effective design inspired by Matthieu Souteyrand.
Understanding the Concept
Think of the light-dark toggle like a light switch in your room. Just as you can switch between light and dark modes depending on the time of day or mood, this toggle enables users to customize their app experience effortlessly. The goal is to provide a hybrid control that merges functionality with visual appeal.
App Design Overview
The design is straightforward and utilizes animations to provide a smooth transition between modes. The light theme provides a bright, engaging interface, while the dark theme reduces eye strain and provides a modern aesthetic.

How to Download the App
Before getting started, you’ll want to download the app. Keep in mind that the uploaded APK is a fat APK, meaning it works on various architectures including:
- armeabi-v7a (ARM 32-bit)
- arm64-v8a (ARM 64-bit)
- x86-64 (x86 64-bit)
If you prefer a smaller APK size, consider cloning the repository and generating one through Android Studio or Visual Studio Code.

- App Crashing: Ensure you have the correct version of Flutter and dependencies installed.
- Toggle Not Working: Double-check your widget tree to ensure the toggle state is properly managed and updated.
- APK Issues: If the APK doesn’t install, try clearing your device’s cache or ensuring it’s compatible with your device architecture.
