FLUTTER DARK MODE SWITCH ANDROID
Ok, we know Android can give us some colors but how can we use them? Passing a list of colors is not that useful or easy to understand. See what it may look like on the m3 side ! In principle, Android can give us a set of colors that match phone wallpaper so your app can blend into the user’s device as part of it rather than a separate entity. Now that we understand what the theme is, we can tackle dynamic colors which is a new feature from Android 12.
You will probably use widgets like Scaffold or AlertDialog which use material themes, but try to not overly depend on it, define your own theme! Material You and dynamic colors It doesn’t mean that you shouldn’t use material themes at all. One of the biggest misconceptions around themes is that people tend to use material themes as the only one available solution, which is most probably not enough to describe the theme that your app needs.
But when you’re working with a designer, they will give you specific requirements on how the app needs to look, meaning theme. It’s just one of the possible implementations of the theme concept and it’s used by material components provided by the Flutter team. Let’s address the elephant in the room – Material Design and its latest version, Material You or Material Design 3.
Rebranding of the app is one possible situation when using theme comes in handy, but what is waaay more likely? Dark mode! When implementing dark mode, using themes is a must and it’s very simple once you understand the core concept.

How can we do better? Ok, you’ve guessed it – when using the theme you can define a single property buttonBackgroundColor and refer to this property instead of color, which means you need to update only buttonBackgroundColor when needed. What do you do in this situation? If you didn’t use themes before, you’ll need to go one by one and adjust them manually. Let’s say the app has like ~50 buttons in different places. Imagine a situation when a designer comes to you and says that every button now needs to be green instead of blue because the company went through a rebranding process. Theme can be understood as simple as a collection of properties, usually colors, text styles, shapes etc., that you can, and should, use across apps to style widgets.

What is the theme and how to fit in the Material?
FLUTTER DARK MODE SWITCH INSTALL
Add the dependency and install dependencies: In the Flutter, we can use the shared preferences library to save the current selected theme and check and set the theme when the application gets loaded. If you want to keep the current theme selection even the user close the application you need to save the currently selected theme in a persistent way. Theme: _light ? _lightTheme : _darkTheme,ĭarkTheme: _darkTheme) Keep the selected theme persistently In this case, switching from toggle does not work because we are forcefully changing the colour. Now when you switch your phone to dark mode app will turn into dark mode automatically without changing.
You can use the same dark Theme data object which we created previously. If you have enabled the dark appearance of your phone you can set the default dark theme by specifying darkTheme property in MaterialApp widget. Also if you want more control of the button to change disable colour, height, padding etc. You can set the default button color by setting buttonColor property. Because some of the hard corded colours may not be properly shown in dark or light theme. In because we are changing the theme it is better to not hardcoding some elements like text and button colours.
