Theming is styling an application so that its look and feel matches your personal design aesthetic or that of an existing enterprise design. You theme your application by controlling its look and feel globally i.e you add the text styles, the icon styles, the primary color, etc. at one place and then propagate them to the. In this article I will present a method of implementing dynamic Dark Mode on Flutter using ThemeMode and the plugin provider.. There are many ways to apply the dynamic theme to Flutter, but the plugin provider is one of the best and most efficient ways I am using in FluCast.. The plugin provider is a mix between Dependency Injection (DI) and state management, built with widgets for widgets

Flutter Switch. A switch is a two-state user interface element used to toggle between ON (Checked) or OFF (Unchecked) states. Typically, it is a button with a thumb slider where the user can drag back and forth to choose an option in the form of ON or OFF. Its working is similar to the house electricity switches ChangeNotifier is a simple class included in the Flutter SDK which provides change notification to its listeners. In other words, if something is a ChangeNotifier, you can subscribe to its changes. You can know more about mixins here. Next we have defined our light and dark theme variables with theme data, you can specify your own colors as you. Since in Flutter everything is widget, the custom theme also belongs to the same concept. To change the theme, we need to reflect it and display the new look on the screen. With reference to that , we've already written about the route and navigation before. We've also shown how we can pass data from one class to another without changing. It's time to change the theme manually. We use DayNightSwitch to do this — it works just like the normal switch widget in Flutter. Inside the onChanged callback of DayNightSwitch, we call theonThemeChanged method, which uses themeNotifier to set the theme and notify the whole app.. void main() => runApp(ChangeNotifierProvider<ThemeNotifier>(builder: (_) => ThemeNotifier(darkTheme), child.

Following is the console output when user switches the Switch widget between on and off states Update: although this widget does work as described it's an anti-pattern. The better approach would be to define the state and let Flutter handle it. Thanks to Pascal Welsch for pointing this out and Iiro Krankka for providing a working example. Settings which are defined in the MaterialApp widget, such as the theme or locale

Flutter has built-in support to light and dark themes. The MaterialApp widget has a property called themeMode.If we specify the darkTheme and theme properties, we can use themeMode to control it. The property defaults to ThemeMode.system, which will use the correct theme based on the device's settings..

With Flutter UI Component app you will be able to obtain a feature-loaded app, worth the user's choice and time.

If you need to change a color for any reason, instead of going through your entire codebase and changing each individual value, you can open CustomColors.
