# Flutter Dark Theme Demo

![Flutter Dark Theme Demo](flutter-dark-theme.png)

This demo will show us how to implement dark theme in flutter projects.

## Setup

Use latest versions of below mentioned plugins in `pubspec.yaml`.

| Plugin | Pub | Explanation |

|--------|-----|-------------|

| [shared_preferences](https://github.com/flutter/plugins) | [![pub package](https://img.shields.io/pub/v/shared_preferences.svg)](https://pub.dev/packages/shared_preferences) | Used to store data locally in key-value pairs.

| [provider](https://github.com/PonnamKarthik/provider) | [![pub package](https://img.shields.io/pub/v/provider.svg)](https://pub.dev/packages/provider) | A wrapper around InheritedWidget to make them easier to use and more reusable.

And then

    flutter pub get

    

### DarkThemePreference

This will save current selected theme locally.

    class DarkThemePreference {

        static const THEME_STATUS = "THEMESTATUS";

        setDarkTheme(bool value) async {

            SharedPreferences prefs = await SharedPreferences.getInstance();

            prefs.setBool(THEME_STATUS, value);

        }

        Future getTheme() async {

            SharedPreferences prefs = await SharedPreferences.getInstance();

            return prefs.getBool(THEME_STATUS) ?? false;

        }

    }

### DarkThemeProvider

This changenotifier will help us to check whether current theme is dark or not.

    class DarkThemeProvider with ChangeNotifier {

        DarkThemePreference darkThemePreference = DarkThemePreference();

        bool _darkTheme = false;

        bool get darkTheme => _darkTheme;

        set darkTheme(bool value) {

            _darkTheme = value;

            darkThemePreference.setDarkTheme(value);

            notifyListeners();

        }

    }

### DarkThemeStyle

We need to define what colors to use when having dark and light theme.

### Check Dark Theme

    Provider.of(context).darkTheme

Finally

    flutter run
